We were referring to hardcoded paths /bin/ls and /bin/cat. For
the purposes of this test, the actual value it's set to doesn't
matter, and it might as well be a non-existent path. All that
matters is that the before and after values have to match, and
that trailing whitespace is stripped. On Windows FileSpec
(correctly) converts /bin/ls to D:\bin\ls though, so the before
and after values won't match. So this patch just correctly builds
up a valid path in a platform-agnostic manner, and verifies that
it matches before and after the set.

This fixes PR22250, which exposed the bug where if there's more than one
TypoExpr in the arguments, once one failed to be corrected none of the
TypoExprs after it would be handled at all thanks to an early return.

Changed the AVX1 tests register spill tail call to return a xmm like the SSE42 version - makes doing diffs between them a lot easier without affecting the spills themselves.
llvm-svn: 226623
The SSE42 version of the AVX1 float stack folding tests will be added shortly, this renames the AVX1 file so that the files will be near each other in a directory listing to help ensure they are kept in sync.

This creates a small internal pass which runs the InstCombiner over
a function. This is the hard part of porting InstCombine to the new pass
manager, as at this point none of the code in InstCombine has access to
a Pass object any longer.
The resulting interface for the InstCombiner is pretty terrible. I'm not
planning on leaving it that way. The key thing missing is that we need
to separate the worklist from the combiner a touch more. Once that's
done, it should be possible for *any* part of LLVM to just create
a worklist with instructions, populate it, and then combine it until
empty. The pass will just be the (obvious and important) special case of
doing that for an entire function body.
For now, this is the first increment of factoring to make all of this
work.

At some point we will need to either provide a pexpect equivalent
on Windows, or provide some other method of doing out-of-process
tests.
Even with a pexpect replacement, it may be worth re-evaluating
some of these tests to see if they would be better served as
in-process tests. The larger issue of coming up with a pexpect
replacement on Windows is tracked in http://llvm.org/pr22274.

ELF linkers by default allow shared libraries to contain undefined references
and it is up to the dynamic linker to look for them.
On COFF and MachO, that is not the case.
This creates a situation where a .so might build on an ELF system, but the build
of the corresponding .dylib or .dll will fail.
This patch changes the cmake build to use -Wl,-z,defs when linking and updates
the dependencies so that -DBUILD_SHARED_LIBS=ON build still works.

don't get muddied up by formatting changes.
Some of these don't really seem like improvements to me, but they also

manually than I do about the particular formatting. =]

The test case is based on the reduction from PR21679 and has to be
freestanding to work correctly, since some of the expected errors (and
some of the problems that were fixed) only occur when the end of the

This addresses part of llvm.org/PR22262. Specifically, it prevents
considering the densities of sub-ranges that have fewer than
TLI.getMinimumJumpTableEntries() elements. Those densities won't help
jump tables.
This is not a complete solution but works around the most pressing
issue.

This reapplies r225379.
ChangeLog:
- The assertion that this commit previously ran into about the inability
to handle indirect variables has since been removed and the backend
can handle this now.
- Testcases were upgrade to the new MDLocation format.
- Instead of keeping a DebugDeclares map, we now use
llvm::FindAllocaDbgDeclare().
Original commit message follows.
Debug info: Teach SROA how to update debug info for fragmented variables.
This allows us to generate debug info for extremely advanced code such as
typedef struct { long int a; int b;} S;
int foo(S s) {
return s.b;
}
which at -O1 on x86_64 is codegen'd into
define i32 @foo(i64 %s.coerce0, i32 %s.coerce1) #0 {
ret i32 %s.coerce1, !dbg !24
}
with this patch we emit the following debug info for this
TAG_formal_parameter [3]
AT_location( 0x00000000
0x0000000000000000 - 0x0000000000000006: rdi, piece 0x00000008, rsi, piece 0x00000004

ConstantArrays constructed during linking can cause quadratic memory
explosion. An example is the ConstantArrays constructed when linking in
GlobalVariables with appending linkage.
Releasing all unused constants can cause a 20% LTO compile-time
slowdown for a large application. So this commit releases unused ConstantArrays
only.

The use of std::future introduces an implicit dependency on the PPL

This fixes file paths on Windows, as you can now write, for example,
file d:\foo\bar.txt, but does not break the case that this tokenization
logic was originally designed for, which is to allow escaping of things
like quotes and double quotes, so that all of the escapable characters
can appear in the same string together.
