Johnny Chen 13eb0eaea7 Patch from Stephen Wilson: 
Extend Swig's include search path.

   Cover both /usr/include and /usr/local/include.  This should allow Swig to find
   system headers such as stdint.h on all platforms we currently support.

NAKAMURA Takumi 2e071faed8 lib/Support/regexec.c: Let Regex LLP64-aware. 
On LLP64 Win64, 'states1' (for small version) was expanded to 'char *' for large version. Thus small version would be mischosen when nstates > 32 regardless of sizeof(long) on Win64.

Johnny Chen 6becf1c924 Add python_api/symbol-context to test getting the symbol context while stopped 
on a frame and to exercise the methods of SBSymbolContext.

Douglas Gregor 6ab34afc4e Fix a regression I caused in r121930. It turns out that 
DeclarationNameInfo instances don't always have a non-NULL
TypeSourceInfo?

Matt Beaumont-Gay e9afc740a8 Delete an extra "Imm5 = ", caught by GCC's -Wsequence-point but not by Clang 
(see PR4579).

Jakob Stoklund Olesen 6e47260a8b Add IntervalMapOverlaps - An iterator for overlapping intervals in two 
IntervalMaps.

The IntervalMaps can have different template parameters, but the KeyT and Traits
types must be the same.

Tests are forthcoming.

Bill Wendling 9613a09e5c Remove fixup_arm_thumb_ldst. The code was never calling the "fixup" stuff for 
it. I.e., it was always an immediate value.

llvm-svn: 121932
 2010-12-16 00:50:33 +00:00
Bill Wendling 637813a258 Add tSpill and tRestore to the opcodes to replace with tSTRi and tLDRi 
respectively.

It may be a bug that these opcodes are getting this far into machine code
generation.

llvm-svn: 121931
 2010-12-16 00:49:54 +00:00
Douglas Gregor c435653998 Check for unexpanded parameter packs in using declarations. As a 
drive-by, make sure to check for unexpanded parameter packs within the
name of a declaration.

llvm-svn: 121930
 2010-12-16 00:46:58 +00:00

Jakob Stoklund Olesen e7601e97e1 Start using SplitKit and MachineLoopRanges in RegAllocGreedy in preparation of 
live range splitting around loops guided by register pressure.

So far, trySplit() simply prints a lot of debug output.

llvm-svn: 121918
 2010-12-15 23:46:13 +00:00
Jakob Stoklund Olesen 5e97781386 Add MachineLoopRanges analysis. 
A MachineLoopRange contains the intervals of slot indexes covered by the blocks
in a loop. This representation of the loop blocks is more efficient to compare
against interfering registers during register coalescing.

Bob Wilson 63fbbc6ef8 Implement builtins for Neon half-precision float conversions. 
Also tweak the VCVT_F32_F16 entry in arm_neon.td to be more consistent with
the other floating-point conversion builtins.  Radar 8068427.

Bill Wendling 7d3bde98f1 If we're changing the frame register to a physical register other than SP, we 
need to use tLDRi and tSTRi instead of tLDRspi and tSTRspi respectively.

Douglas Gregor a02a72af8d Check for unexpanded parameter packs in various kinds of 
declarations. This is a work in progress, as I go through the C++
declaration grammar to identify where unexpanded parameter packs can
occur.

 2010-12-15 23:18:36 +00:00
Bob Wilson d7f8bd1c14 Teach the Neon intrinsic generator to widen half-precision float types. 
This isn't currently used for anything but I ran into it when experimenting
with some changes, and it might be useful in the future.

Johnny Chen 8e74416cd5 Fix one of the golden output of "frame variable -t *self" to be: 
"(MyString) *self"

llvm-svn: 121907

Rafael Espindola 50baf9d984 Typo. 
llvm-svn: 121906
 2010-12-15 22:33:06 +00:00
Owen Anderson 1cf8881299 Add an InstCombine transform to recognize instances of manual overflow-safe addition 
(performing the addition in a wider type and explicitly checking for overflow), and
fold them down to intrinsics.  This currently only supports signed-addition, but could
be generalized if someone works out the magic constant formulas for other operations.

Fixes <rdar://problem/8558713>.

 2010-12-15 22:16:21 +00:00
Bob Wilson fa27a8621c Add Neon VCVT instructions for f32 <-> f16 conversions. 
Clang is now providing intrinsics for these and so we need to support them
in the backend.  Radar 8068427.

llvm-svn: 121902

Douglas Gregor fe2c8bc327 Teach the RecursiveASTVisitor to traverse the type-location 
information for all of the explicit casts.

llvm-svn: 121900
 2010-12-15 22:07:31 +00:00
Douglas Gregor a8461bb439 Test that all of the relevant types properly compute the "contains 
unexpanded parameter pack" bit and that the recursive AST visitor can
then find those unexpanded parameter packs.

Johnny Chen 763d1a17a1 Fix typos in SBBreakpoint::GetThreadIndex()/GetThreadName(), and test sequences 
for the two API calls.

Greg Clayton e2956eeb87 Fix invalid conversion from "const char *" to "char *" for linux systems. strchr() on darwin returns "char *" so we weren't seeing this issue on MacOSX. 
llvm-svn: 121897
 2010-12-15 20:52:40 +00:00
Greg Clayton bdf4c6ac4f Fixed an error where the thread index was being returned as zero in "uint32_t SBBreakpoint::GetThreadIndex() const" even when it isn't specified. It should be UINT32_MAX to indicate there is no thread index set for the breakpoint (the breakpoint isn't thread specific). Also fixed the ThreadSpec.cpp to use UINT32_MAX instead of -1. Fixed the logging Printf statement in "uint32_t SBBreakpoint::GetThreadIndex() const" to not print the address of the "index" function from <string.h>!

Dan Gohman 05b18f143f Reapply r121886, and also update DecomposeGEPExpression to keep 
it in sync.

llvm-svn: 121895

Jim Ingham 5949cfe11b Added a test for finding the correct values for ivars when a property causes the ivar offsets 
in the DWARF to be incorrect.
