a38c737e85 When a function takes a variable number of pointer arguments, with a zero
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

9619965bcc Speed up isBytecodeLPath from 20s to .01s in common cases. This makes -native
not completely painful to use.  Once we decide a directory has a bytecode
library, we know it this function returns true, no need to scan entire directories.

e20b536b12 1. Do not use .c_str() to keep a persistent handle on a temporary string.
2. Concatenate -lfoo and -L/bar options into a single option instead of
   passing "-L /bar" (for example) which doesn't work on Darwin.
3. Send -v output to stderr instead of stdout

46a7fdeb66 Implement PR614:
These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.

eb6bad32e9 Fix PR576.
Instead of emitting a JIT stub that looks like this:

internal void %l1_main_entry_2E_ce_wrapper(int) {
header:
        %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) )           ; <sbyte*> [#uses=1]
        %resolverCast = cast sbyte* %resolver to void (int)*            ; <void (int)*> [#uses=1]
        call void %resolverCast( int %0 )
        ret void
}

Emit one that looks like this:

internal void %l1_main_entry_2E_ce_wrapper(int) {
Entry:
	%fpcache = load void (int)** %l1_main_entry_2E_ce.fpcache               ; <void (int)*> [#uses=2]
        %isNull = seteq void (int)* %fpcache, null              ; <bool> [#uses=1]
        br bool %isNull, label %lookupfp, label %usecache

usecache:               ; preds = %lookupfp, %Entry
        %fp = phi void (int)* [ %resolverCast, %lookupfp ], [ %fpcache, %Entry ]            ; <void (int)*> [#uses=1]
        call void %fp( int %0 )
        ret void

lookupfp:               ; preds = %Entry
        %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) )           ; <sbyte*> [#uses=1]
        %resolverCast = cast sbyte* %resolver to void (int)*            ; <void (int)*> [#uses=2]
        store void (int)* %resolverCast, void (int)** %l1_main_entry_2E_ce.fpcache
        br label %usecache
}


This makes the JIT debugger *MUCH* faster on large programs, as
getPointerToNamedFunction takes time linear with the size of the program, and
before we would call it every time a function in the text module was called from
the safe module (ouch!).

04d734c2f6 Final Changes For PR495:
This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:

makeReadable        -> makeReadableOnDisk
makeWriteable       -> makeWriteableOnDisk
makeExecutable      -> makeExecutableOnDisk
setStatusInfo       -> setStatusInfoOnDisk
createDirectory     -> createDirectoryOnDisk
createFile          -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy             -> eraseFromDisk
rename              -> renamePathOnDisk

These changes pass the Linux Deja Gnu tests.

5534b2d505 For PR495:
Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:

appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

Changes pass Dejagnu and llvm-test/SingleSource tests.

ec6c11679f Make the CBackend actually get included in llc by using USEDLIBS instead of
USEDLIB as the variable to which "CBackend" is appended. The surrounding
if clause is safe because currently the configure script ensures that the
CBackend target is always added to TARGETS_TO_BUILD. By using a non-hard
coded construct in the makefile, we gain uniformity and the ability to
change the default set of targets by only changing the configure script.

868f3fb2e0 Implement the --enable-targets= feature of the configure script. The make
variable TARGETS_TO_BUILD is used to determine which targets in lib/Target

test suite.

1. Get rid of TOOLLINKOPTS as it is a hold over from llvm-test and only
   used to communicate additional libraries to the linker. The *standard*
   way to do that is with the LIBS variable which this change supports.

2. Allow the TARGETS_TO_BUILD variable to be set from the configuration
   substitution. This is the result of the --enable-target= parameter to
   the configure script.

fb233f641d Prevent output of bytecode to std::cout unless the --force flag is given.
This prevents bytecode splats with usage like: cat file.ll | llvm-as -

298f85282c For PR351:
* Place a try/catch block around the entire tool to Make sure std::string
  exceptions are caught and printed before exiting the tool.
* Make sure we catch unhandled exceptions at the top level so that we don't
  abort with a useless message but indicate than an unhandled exception was
  generated.

a0e66891ae Fix the build on PowerPC/Darwin - it thought we were declaring a new
function or something. Since FileRemover takes a const reference to
sys::Path, we need to pass an actual sys::Path variable.
