Nico Weber cb4c7f4b18 Move a declaration closer to its use. No functionality change.

Jakob Stoklund Olesen 7bca670a8b Remove a special case that doesn't seem necessary any longer. 
Back when this exception was added, it was skipping a lot more code, but
now it just looks like a premature optimization.

Jakob Stoklund Olesen b089483993 Use getNumOperands() instead of Operands.size(). 
The representation of the Operands array is going to change soon so it
can be allocated from a BumpPtrAllocator.

Benjamin Kramer a296431357 Clean out release notes for clang 3.3

Benjamin Kramer 76268ac682 X86: Turn mul of <4 x i32> into pmuludq when no SSE4.1 is available. 
pmuludq is slow, but it turns out that all the unpacking and packing of the
scalarized mul is even slower. 10% speedup on loop-vectorized paq8p.

Benjamin Kramer b2f0a2bd4b X86: Emit vector sext as shuffle + sra if vpmovsx is not available. 
Also loosen the SSSE3 dependency a bit, expanded pshufb + psra is still better
than scalarized loads. Fixes PR14590.

Andy Gibbs d02bf1d232 Fix build issue when building lld against libstdc++ 4.7

Craig Topper c9dcbe6987 Use a negative value to represent INVALID_SIMPLE_VALUE_TYPE instead of 256. Its much cheaper for the isSimple() checks to look for values less than 0 rather than a value greater than 255. This shaves ~8k off the size of the llc binary on x86-64.

Argyrios Kyrtzidis 9fd1571e7a [libclang] Fix crash when code-completing a macro invocation that 
reached EOF and did not expand the argument into the source context.

 2012-12-22 04:48:10 +00:00
Argyrios Kyrtzidis 430a938fde [libclang] Don't try to translate diagnostics from the precompiled preamble to the 
code-completion results, the SourceManager state may be slightly
different when code-completing.

And we don't even care for diagnostics when code-completing, anyway.

llvm-svn: 170979
 2012-12-22 04:48:08 +00:00
Argyrios Kyrtzidis 9999f4f88b [libclang] Check for the 'LIBCLANG_NOTHREADS' environment variable before creating 
a separate thread for code-completion.

Craig Topper 8289b327ac Add vAny and Metadata to the switch in getSizeInBits for consistency since every other enum was listed.

Ted Kremenek 6cae9ec643 Add back -Wduplicate-enum which I mistakenly removed. 
This was removed with -Wunique-enum, which is still removed.  The
corresponding thread on cfe-comments for that warning is here:

  http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-September/024224.html

If we get specific user feedback for -Wduplicate-enum we can evaluate
whether or not to keep it.

Daniel Dunbar fa40268fb7 [utils] Tweak utils/clang-parse-diagnostics-file to ignore autoconf diagnostics. 
- Also, don't print headers if we aren't going to print any diagnostics.

Bill Wendling c79e42c5ce Change 'AttrVal' to 'AttrKind' to better reflect that it's a kind of attribute instead of the value of the attribute.

Ted Kremenek c632467e2b Fix typo: objc_no_direct_instance_variable_assignmemt => objc_no_direct_instance_variable_assignment.

uninitialized value against a default value. Found by -fsanitize=enum.

Nadav Rotem d5aae980cb In some cases, due to scheduling constraints we copy the EFLAGS. 
The only way to read the eflags is using push and pop. If we don't
adjust the stack then we run over the first frame index. This is
not something that we want to do, so we have to make sure that
our machine function does not copy the flags. If it does then
we have to emit the prolog that adjusts the stack.

hopefully making it less error prone.

Matt Beaumont-Gay cab0f3131e Insulate this test from the whims of the random number generator. 
Our internal buildbot just failed because the tempfile happened to be named
'nodefaultlib-lcGA7k.o', which contains the substring '-lc'.

Jim Ingham e2231ac783 Added an SBAPI to get the PythonPath (if the Host knows how to do that). And a -P option to the Driver 
to print it out.  Changed dotest.py to use that to find the PythonPath it should use given the lldb binary
it was told to run.

 2012-12-21 22:22:26 +00:00
Ted Kremenek 44c2a2a26e Change checkUnsafeAssignLiteral() to use the new Sema::CheckLiteralKind(). 
Along the way, fix a bug in CheckLiteralKind(), previously in diagnoseObjCLiteralComparison, where we didn't ignore parentheses
in boxed expressions for purpose of classification.

In other words, both @42 and @(42) should be classified as numeric
literals.
