2012-03-02Fix an ABI problem with ptrdiff_t and intptr_t on PPC32Hal Finkel
ptrdiff_t on PPC32 on Linux, etc. should be int not long. This does not matter for C, but it does matter for C++ because of name mangling. The preprocessor test has been changed accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151935 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-30Introduce TargetInfo::hasFeature() to query various feature names inDouglas Gregor
each of the targets. Use this for module requirements, so that we can pin the availability of certain modules to certain target features, e.g., provide a module for xmmintrin.h only when SSE support is available. Use these feature names to provide a nearly-complete module map for Clang's built-in headers. Only mm_alloc.h and unwind.h are missing, and those two are fairly specialized at the moment.

2012-01-28Use defined-at-zero behavior for CLZ/CTZ builtins on PowerPC.Bob Wilson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149181 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-26Make clz/ctz builtins defined for zero on ARM targets. rdar://10732455Bob Wilson
ARM supports clz and ctz directly and both operations have well-defined results for zero. There is no disadvantage in performance to using the defined-at-zero versions of llvm.ctlz/cttz intrinsics. We're running into ARM-specific code written with the assumption that __builtin_clz(0) == 32, even though that value is technically undefined. The code is failing now because of llvm optimizations that are taking advantage of the undef behavior (specifically svn r147255). There's nothing wrong with that optimization on x86 where any incorrect assumptions about __builtin_clz(0) will quickly be exposed. For ARM, though, optimizations based on that undef behavior are likely to cause subtle bugs. Other targets with defined-at-zero clz/ctz support may want to override the default behavior as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149086 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-13remove assertions in the Hexagon backend specific clang driverSebastian Pop
Patch from Jyotsna Verma: I have made the changes to remove assertions in the Hexagon backend specific clang driver. Instead of asserting on invalid arch name, it has been modified to use the default value. I have changed the implementation of the CPU flag validation for the Hexagon backend. Earlier, the clang driver performed the check and asserted on invalid inputs. In the new implementation, the driver passes the last CPU flag (or sets to "v4" if not specified) to the compiler (and also to the assembler and linker which perform their own check) instead of asserting on incorrect values. This patch changes the setCPU function for the Hexagon backend in clang/lib/Basic/Targets.cpp which causes the compiler to error out on incorrect CPU flag values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148139 91177308-0d34-0410-b5e6-96231b3b80d8
