Akira Hatanaka f1412e4d2f Remove MipsTargetLowering::LowerFP_TO_SINT. Patterns for fp_to_sint have already 
been defined in MipsInstrFPU.td.

Akira Hatanaka 92a26d4e18 Change initial value of MaxCallFrameSize. MipsFI::getMaxCallFrameSize() should 
return 0 if there are no function calls made.

Francois Pichet f83114dceb Fix 3 MSVC warnings: 
'void (__cdecl *)()' differs in parameter lists from 'void (__cdecl *)(void)'

atexit really expects a "void f(void)" function.

Francois Pichet 58b09c9366 Fix MSVC warning: "is out of range for enum constant" 
MSVC doesn't support 64 bit enum. 
OpcodeMask is not used anywhere in the code base.

Rafael Espindola 33dacdfe66 Fix some issues Duncan found in the previous commit. 
I kept the reference to the ABI since that is the common case. The
-fno-asynchronous-unwind-tables option is a user controlled way of breaking
the ABI.

Frits van Bommel 308a534431 Fix warning in the CMake build about redefining LLVM_PATH_XDOT_PY by making sure both definitions are identical. This used to produce warnings like

Argyrios Kyrtzidis 0246d63715 [tablegen] A couple of changes to ClangDiagnosticEmmitter. 
-Emit an empty warning option as string ("") instead of 0.
-For diagnostic names also emit the size of the string.

Cameron Zwarich 3088e0a179 Make tTAILJMPr/tTAILJMPrND emit a tBX without a preceding MOV of PC to LR. This 
fixes <rdar://problem/9495913>

llvm-svn: 132042
 2011-05-25 04:45:27 +00:00
Cameron Zwarich 310b3472ec Change the order of tBX's operands so that the predicate operands come after the 
target register, matching BX. I filed this bug because I was confused at first:

PR10007 - ARM branch instructions have inconsistent predicate operand placement

Charles Davis b0c4f39173 Add a test for .seh_pushframe parsing. Fix the bug exposed by it (and another 
one I found by inspection).

 2011-05-25 04:08:15 +00:00
Rafael Espindola fc9bae6f8b Replace the -unwind-tables option with a per function flag. This is more 
LTO friendly as we can now correctly merge files compiled with or without
-fasynchronous-unwind-tables.

Charles Davis fc1e7ce850 Add a test for the .seh_handler directive. Fix problems with the parsing 
method exposed by the test. While we're at it, simplify the .seh_proc
parsing method.

Evan Cheng 1b55f56b01 Fix LoopUnswitch bug. RewriteLoopBodyWithConditionConstant can delete a dead 
case of a switch instruction. Back off this optimization when this would
eliminate all of the predecessors to the latch.

Sorry, I am unable to reduce a reasonably sized test case.

Eli Friedman bacb17906a Change condition for determining whether a function is small for inlining metrics so that very long functions 
with few basic blocks are not re-analyzed.

Charles Davis 7f6176c3f9 Implement the rest of the SEH directive-parsing methods in the COFFAsmParser. 
Add a size alignment check to the .seh_stackalloc directive parser. Add a
more descriptive error message to the .seh_handler directive parser.

Add methods to the TargetAsmInfo struct in support of all this.

Akira Hatanaka 5e16c6a9b2 Implement byval structure argument passing. The following limitations or 
deficiencies exist:

- Works only if ABI is o32.
- Zero-sized structures cannot be passed.
- There is a lot of redundancy in generated code.

Dan Gohman 0573b55c2b Make DecomposeGEPExpression check SimplifyInstruction only 
after checking for a GEP, so that it matches what GetUnderlyingObject
does. This fixes an obscure bug turned up by bugpoint in the testcase
for PR9931.

Charles Davis 97019c709d Add a method to TargetRegisterInfo to get the register number that the Win64 EH 
scheme uses internally. Implement it for x86 (the only architecture that LLVM
supports for which this matters right now).
