2011-12-02When we're passing a vector with an illegal type through memory on x86-64, ↵Eli Friedman
use byval so we're sure the backend does the right thing. Fixes va_arg with illegal vectors and an obscure ABI mismatch with __m64 vectors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145652 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-10Constant expression evaluation refactoring:Richard Smith
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions, and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert behaviour. - Factor out evaluation of bitfield bit widths. - Fix a few places which would evaluate an expression twice: once to determine whether it is a constant expression, then again to get the value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141561 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-21ANSI C requires that a call to an unprototyped function type succeedJohn McCall
if the definition has a non-variadic prototype with compatible parameters. Therefore, the default rule for such calls must be to use a non-variadic convention. Achieve this by casting the callee to the function type with which it is required to be compatible, unless the target specifically opts out and insists that unprototyped calls should use the variadic rules. The only case of that I'm aware of is the x86-64 convention, which passes arguments the same way in both cases but also sets a small amount of extra information; here we seek to maintain compatibility with GCC, which does set this when calling an unprototyped function. Addresses PR10810 and PR10713. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140241 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.Bob Wilson
A homogeneous aggregate is an aggregate data structure where after flattening any nesting there are 1 to 4 elements of the same base type that is either a float, double, or Neon vector. All Neon vectors of the same size, either 64 or 128 bits, are treated as equivalent for this purpose. When using the AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by expanding them into a sequence of their base types. This requires extending the existing support for expanded arguments to handle not only structs, but also constant arrays and complex types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136767 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-01Revert "Re-enable byval for ARM in clang. rdar://problem/7662569"Bob Wilson
This reverts commit 67d097e1232b7d66f58989c16a45b8a11721f76e. We found a miscompile with ARM byval, which is still being investigated. In the meantime, this works around the problem by disabling ARM byval.

2011-08-01Implement MipsABIInfo::EmitVAArg. This fix enables clang to complete compilationAkira Hatanaka
without bailing out when va_arg is an aggregate expression. However, alignment checking needs to be added in isSafeToEliminateVarargsCast in InstCombineCalls.cpp in order to produce correct mips code (see link below). http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-July/042047.html git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136647 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx ↵Eli Friedman
should not imply -mno-sse. Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__. clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much. <rdar://problem/9694837> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134770 91177308-0d34-0410-b5e6-96231b3b80d8
