FileCheck [1/12]: Move variable table in new object
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds a new class to hold
pattern matching global state.
The table holding the values of FileCheck variable constitutes some sort
of global state for the matching phase, yet is passed as parameters of
all functions using it. This commit create a new FileCheckPatternContext
class pointed at from FileCheckPattern. While it increases the line
count, it separates local data from global state. Later commits build
on that to add numeric expression global state to that class.

FileCheck [2/12]: Stricter parsing of -D option
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.
Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

FileCheck: Improve FileCheck variable terminology
Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.

FileCheck [3/12]: Stricter parsing of @LINE expressions
Summary:
This patch is part of a patch series to add support for FileCheck

diagnostics for the @LINE expressions.
Rather than detect parsing errors at matching time, this commit adds
enhance parsing to detect issues with @LINE expressions at parse time
and diagnose them more accurately.

FileCheck [4/12]: Introduce @LINE numeric expressions
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces the @LINE numeric
expressions.
This commit introduces a new syntax to express a relation a numeric
value in the input text must have with the line number of a given CHECK
pattern: [[#<@LINE numeric expression>]]. Further commits build on that
to express relations between several numeric values in the input text.
To help with naming, regular variables are renamed into pattern
variables and old @LINE expression syntax is referred to as legacy
numeric expression.
Compared to existing @LINE expressions, this new syntax allow arbitrary
spacing between the component of the expression. It offers otherwise the
same functionality but the commit serves to introduce some of the data
structure needed to support more general numeric expressions.

FileCheck: Improve FileCheck variable terminology
Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.

FileCheck [4/12]: Introduce @LINE numeric expressions
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces the @LINE numeric
expressions.
This commit introduces a new syntax to express a relation a numeric
value in the input text must have with the line number of a given CHECK
pattern: [[#<@LINE numeric expression>]]. Further commits build on that
to express relations between several numeric values in the input text.
To help with naming, regular variables are renamed into pattern
variables and old @LINE expression syntax is referred to as legacy
numeric expression.
Compared to existing @LINE expressions, this new syntax allow arbitrary
spacing between the component of the expression. It offers otherwise the
same functionality but the commit serves to introduce some of the data
structure needed to support more general numeric expressions.

FileCheck: Improve FileCheck variable terminology
Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.

FileCheck [5/12]: Introduce regular numeric variables
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces regular numeric
variables which can be set on the command-line.
This commit introduces regular numeric variable that can be set on the
command-line with the -D option to a numeric value. They can then be
used in CHECK patterns in numeric expression with the same shape as
@LINE numeric expression, ie. VAR, VAR+offset or VAR-offset where offset
is an integer literal.
The commit also enable strict whitespace in the verbose.txt testcase to
check that the position or the location diagnostics. It fixes one of the
existing CHECK in the process which was not accurately testing a
location diagnostic (ie. the diagnostic was correct, not the CHECK).

FileCheck [1/12]: Move variable table in new object
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds a new class to hold
pattern matching global state.
The table holding the values of FileCheck variable constitutes some sort
of global state for the matching phase, yet is passed as parameters of
all functions using it. This commit create a new FileCheckPatternContext
class pointed at from FileCheckPattern. While it increases the line
count, it separates local data from global state. Later commits build
on that to add numeric expression global state to that class.

FileCheck [2/12]: Stricter parsing of -D option
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.
Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

FileCheck [2/12]: Stricter parsing of -D option
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.
Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

FileCheck [1/12]: Move variable table in new object
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds a new class to hold
pattern matching global state.
The table holding the values of FileCheck variable constitutes some sort
of global state for the matching phase, yet is passed as parameters of
all functions using it. This commit create a new FileCheckPatternContext
class pointed at from FileCheckPattern. While it increases the line
count, it separates local data from global state. Later commits build
on that to add numeric expression global state to that class.

FileCheck [2/12]: Stricter parsing of -D option
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.
Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

Summary:
This patch is part of a patch series to add support for FileCheck

The table holding the values of FileCheck variable constitutes some sort

class pointed at from FileCheckPattern. While it increases the line
count, it separates local data from global state. Later commits build
on that to add numeric expression global state to that class.

FileCheck [4/12]: Introduce @LINE numeric expressions
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces the @LINE numeric
expressions.
This commit introduces a new syntax to express a relation a numeric
value in the input text must have with the line number of a given CHECK
pattern: [[#<@LINE numeric expression>]]. Further commits build on that
to express relations between several numeric values in the input text.
To help with naming, regular variables are renamed into pattern
variables and old @LINE expression syntax is referred to as legacy
numeric expression.
Compared to existing @LINE expressions, this new syntax allow arbitrary
spacing between the component of the expression. It offers otherwise the
same functionality but the commit serves to introduce some of the data
structure needed to support more general numeric expressions.

FileCheck: Improve FileCheck variable terminology
Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.

FileCheck [2/12]: Stricter parsing of -D option
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch gives earlier and better
diagnostics for the -D option.
Prior to this change, parsing of -D option was very loose: it assumed
that there is an equal sign (which to be fair is now checked by the
FileCheck executable) and that the part on the left of the equal sign
was a valid variable name. This commit adds logic to ensure that this
is the case and gives diagnostic when it is not, making it clear that
the issue came from a command-line option error. This is achieved by
sharing the variable parsing code into a new function ParseVariable.

FileCheck [1/12]: Move variable table in new object
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds a new class to hold
pattern matching global state.
The table holding the values of FileCheck variable constitutes some sort
of global state for the matching phase, yet is passed as parameters of
all functions using it. This commit create a new FileCheckPatternContext
class pointed at from FileCheckPattern. While it increases the line
count, it separates local data from global state. Later commits build
on that to add numeric expression global state to that class.

FileCheck [4/12]: Introduce @LINE numeric expressions
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch introduces the @LINE numeric
expressions.
This commit introduces a new syntax to express a relation a numeric
value in the input text must have with the line number of a given CHECK
pattern: [[#<@LINE numeric expression>]]. Further commits build on that
to express relations between several numeric values in the input text.
To help with naming, regular variables are renamed into pattern
variables and old @LINE expression syntax is referred to as legacy
numeric expression.
Compared to existing @LINE expressions, this new syntax allow arbitrary
spacing between the component of the expression. It offers otherwise the
same functionality but the commit serves to introduce some of the data
structure needed to support more general numeric expressions.

FileCheck: Improve FileCheck variable terminology
Summary:
Terminology introduced by [[#]] blocks is confusing and does not
integrate well with existing terminology.
First, variables referred by [[]] blocks are called "pattern variables"
while the text a CHECK directive needs to match is called a "CHECK
pattern". This is inconsistent with variables in [[#]] blocks since
[[#]] blocks are also found in CHECK pattern yet those variables are
called "numeric variable".
Second, the replacing of both [[]] and [[#]] blocks by the value of the
variable or expression they contain is represented by a
FileCheckPatternSubstitution class. The naming refers to being a
substitution in a CHECK pattern but could be wrongly understood as being
a substitution of a pattern variable.
Third and lastly, comments use "numeric expression" to refer both to the
[[#]] blocks as well as to the numeric expressions these blocks contain
which get evaluated at match time.
This patch solves these confusions by
- calling variables in [[]] and [[#]] blocks as string and numeric
variables respectively;
- referring to [[]] and [[#]] as substitution *blocks*, with the former
being a string substitution block and the latter a numeric
substitution block;
- calling [[]] and [[#]] blocks to be replaced by the value of a
variable or expression they contain a substitution (as opposed to
definition when these blocks are used to defined a variable), with the
former being a string substitution and the latter a numeric
substitution;
- renaming the FileCheckPatternSubstitution as a FileCheckSubstitution
class with FileCheckStringSubstitution and
FileCheckNumericSubstitution subclasses;
- restricting the use of "numeric expression" to refer to the expression
that is evaluated in a numeric substitution.
While numeric substitution blocks only support numeric substitutions of
numeric expressions at the moment there are plans to augment numeric
substitution blocks to support numeric definitions as well as both a
numeric definition and numeric substitution in the same numeric
substitution block.
