2007-12-11- Improved v8i16 shuffle lowering. It now uses pshuflw and pshufhw as much asEvan Cheng
possible before resorting to pextrw and pinsrw. - Better codegen for v4i32 shuffles masquerading as v8i16 or v16i8 shuffles. - Improves (i16 extract_vector_element 0) codegen by recognizing (i32 extract_vector_element 0) does not require a pextrw. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44836 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-11Move TargetData::hostIsLittleEndian out of line, which means we Chris Lattner
don't have to #include config.h in it. #including config.h breaks other projects that have their own autoconf stuff and try to #include the llvm headers. One obscure example is llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44825 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44819 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Provide convenient way to disable CFI stuff for old/broken assemblers.Anton Korobeynikov
Use it for Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44818 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Disable cfi directives for now, darwin does't support them.Chris Lattner
These should probably be something like: CFI(".cfi_def_cfa_offset 16\n") where CFI is defined to a noop on darwin and other platforms that don't support those directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44803 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10And finally annotate X86-64 version of callback. Anton Korobeynikov
All bad stuff from SSE version is implicitely inherited :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44794 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-10Annotate JIT callback function with call frame infromation. Anton Korobeynikov
This will allow us (theoretically) to unwind through JITer. The code wasn't verified, so I'm pretty sure offsets are wrong :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44792 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-08Fix a significant code quality regression I introduced on PPC64 quite Chris Lattner
a while ago. We now produce: _foo: mflr r0 std r0, 16(r1) ld r2, 16(r1) std r2, 0(r3) ld r0, 16(r1) mtlr r0 blr instead of: _foo: mflr r0 std r0, 16(r1) lis r0, 0 ori r0, r0, 16 ldx r2, r1, r0 std r2, 0(r3) ld r0, 16(r1) mtlr r0 blr for: void foo(void **X) { *X = __builtin_return_address(0); } on ppc64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44701 91177308-0d34-0410-b5e6-96231b3b80d8

different places to mean different things. Document what the one in PPCFunctionInfo means and when it is valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44699 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-03Rather than having special rules like "intrinsics cannotDuncan Sands
