83df3058ed UpdatePHINodes in BasicBlockUtils should not crash on duplicate predecessors
UpdatePHINodes has an optimization to reuse an existing PHI node, where it
first deletes all of its entries and then replaces them. Unfortunately, in the
case where we had duplicate predecessors (which are allowed so long as the
associated PHI entries have the same value), the loop removing the existing PHI
entries from the to-be-reused PHI would assert (if that PHI was not the one
which had the duplicates).

7d2e2df7f2 Fix DAGCombiner::visitFP_EXTEND to ignore indexed loads
DAGCombiner::visitFP_EXTEND will apply the following transformation:

  fold (fpext (load x)) -> (fpext (fptrunc (extload x)))

but the implementation does not handle indexed loads (pre/post inc.), but did
not specifically ignore them either (unlike for extending loads, which it
already ignored), causing an assert when the transformation was applied to an
indexed load. This is the minimal fix for correctness (causing the
transformation to be skipped for indexed loads).

Unfortunately, I don't have an in-tree test case.

70c25749d2 [MC][AsmParser] Hook for post assembly file processing
This patch handles LLVM standalone assembler (llvm-mc) ELF flag setting based on input file
directive processing.

Mips assembly requires processing inline directives that directly and
indirectly affect the output ELF header flags. This patch handles one
".abicalls".

To process these directives we are following the model the code generator
uses by storing state in a container as we go through processing and when
we detect the end of input file processing, AsmParser is notified and we
update the ELF header flags through a MipsELFStreamer method with a call from
MCTargetAsmParser::emitEndOfAsmFile(MCStreamer &OutStreamer).

This patch will allow other targets the same functionality.

6fab174840 SLPVectorizer: Sort inputs to commutative binary operations
Sort the operands of the other entries in the current vectorization root
according to the first entry's operands opcodes.

%conv0 = uitofp ...
%load0 = load float ...

= fmul %conv0, %load0
= fmul %load0, %conv1
= fmul %load0, %conv2

Make sure that we recursively vectorize <%conv0, %conv1, %conv2> and <%load0,
%load0, %load0>.

This makes it more likely to obtain vectorizable trees. We have to be careful
when we sort that we don't destroy 'good' existing ordering implied by source
order.

ca9c6bd8ed DebugInfo: Fix ordering of members after r191928
In the case (shown in the attached test) where a member function
definition was emitted into debug info the following could occur:

1) build the debug info for the member function definition
2) in (1), build the debug info for the member function declaration
3) construct and add the member function declaration DIE
4) add it to its context
5) build its context (the type it is a member of)
6) construct the members and add them to the type
7) except don't add member functions because "getOrCreateSubprogram"
adds the function to its parent anyway
8) except we're only partway through building this subprogram
declaration so it hasn't been added yet - but we returned the partially
constructed DIE (since it's already in the MDNode->DIE mapping to avoid
infinitely recursing trying to create the member function DIE)
9) once the type is constructed, add the member function to it
10) now the members are out of order (the member function being defined
is listed as the last member, even though it was declared as the first)

To avoid this, construct the context of the subprogram DIE before we
query to see if it exists. That way we never end up creating it before
creating its context and ending up in this situation.

Alternatively, the type construction that visits/builds all the members
could call something like getOrCreateSubprogram, but that doesn't ever
do the "add to context" step. Then the type building code would always
be responsible for adding members (and the subprogram "addToContextDIE"
would no-op because the context building would have added the subprogram
declaration to the type/context DIE already).

(the test cases updated were overly-sensitive to offsets or abbreviation
numbers. We don't have a nice way to make these tests more robust as yet
- multiline FileCheck matches would be required)

476b8f3036 Fixed a bug with section names containing special characters.
Changed the dwarf aranges code to not use getLabelEndName, as it turns out it's not reliable to call that given user-defined section names. Section names can have characters in that aren't representable as symbol names.

The dwarf-aranges test case has been updated to include a special character, to check this.

This fixes pr17416.

5e2eba8c18 Pull fptrunc's upwards through selects when one of the select's selectands was a constant. This has a number of benefits, including producing small immediates (easier to materialize, smaller constant pools) as well as being more likely to allow the fptrunc to fuse with a preceding instruction (truncating selects are unusual).

957eba35f2 DebugInfo: Avoid redundantly adding child DIEs to parents.
DIE::addChild had a shortcircuit that silently no-op'd when a child was
readded to the same parent. This hid some quirky/redundant code in
DwarfDebug/CompileUnit. By removing that functionality and replacing it
with an assert I was able to find and cleanup those cases, mostly
centering around adding members to types in various circumstances.

1) The original oddity I noticed while working on type units (which
actually was helping me in the short term, by accident) was the
addToContextOwner call in constructTypeDIE. This call was completely
bogus (why was it only done for non-virtual types? what relevance does
that have at all) and redundant with the more uniform addToContextOwner
made in getOrCreateTypeDIE.

2) If a member function definition was visited (createSubprogramDIE), it
would attempt to build the member function declaration. The declaration
DIE would then be added to its context, but in building the context (the
type for which this function is a member) the members of the type would
be added to the type automatically, so by the time the context was
constructed, the member function was already associated with it.

3) The same as (2) but without the member function being constructed
first. Whenever a type was constructed, the members would be created and
member functions would be created by getOrCreateSubprogramDIE - this
would lead to the subprogram being added to the (incomplete) type
already, then the general member-construction code would add it again.

a88c415234 Optimize linkonce_odr unnamed_addr functions during LTO.
Generalize the API so we can distinguish symbols that are needed just for a DSO
symbol table from those that are used from some native .o.

The symbols that are only wanted for the dso symbol table can be dropped if
llvm can prove every other dso has a copy (linkonce_odr) and the address is not
important (unnamed_addr).
