* Adapt the x86 build_vector dagcombine to the current state of the legalizer.Nate Begeman2009-06-055-59/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | build vectors with i64 elements will only appear on 32b x86 before legalize. Since vector widening occurs during legalize, and produces i64 build_vector elements, the dag combiner is never run on these before legalize splits them into 32b elements. Teach the build_vector dag combine in x86 back end to recognize consecutive loads producing the low part of the vector. Convert the two uses of TLI's consecutive load recognizer to pass LoadSDNodes since that was required implicitly. Add a testcase for the transform.

* The DWARF unwind info was incorrect. While compiling withBill Wendling2009-06-041-15/+16
| | | | | | | | | | | | | | | | | `-fomit-frame-pointer', we would lack the DW_CFA_advance_loc information for a lot of function, and then they would be `0'. The linker (at least on Darwin) needs to encode the stack size. In some cases, the stack size is too large to directly encode. So the linker checks to see if there is a "subl $xxx,%esp" instruction at the point where the `DW_CFA_def_cfa_offset' says the pc was. If so, the compact encoding records the offset in the function to where the stack size is embedded. But because the `DW_CFA_advance_loc' instructions are missing, it looks before the function and dies. So, instead of emitting the EH debug label before the stack adjustment operations, emit it afterwards, right before the frame move stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72898 91177308-0d34-0410-b5e6-96231b3b80d8
* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-04265-1925/+2375
| | | | | | | | | | | | | | | | integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately.

* Fix FP_TO_UINT->i32 on ppc32 -mcpu=g5. This wasDale Johannesen2009-06-043-16/+17
| | | | | | | | | | | | | | | | using Promote which won't work because i64 isn't a legal type. It's easy enough to use Custom, but then we have the problem that when the type legalizer is promoting FP_TO_UINT->i16, it has no way of telling it should prefer FP_TO_SINT->i32 to FP_TO_UINT->i32. I have uncomfortably hacked this by making the type legalizer choose FP_TO_SINT when both are Custom. This fixes several regressions in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72891 91177308-0d34-0410-b5e6-96231b3b80d8
