2008-08-07Re-enable elimination of unnecessary SUBREG_TO_REG instructions inDan Gohman
LowerSubregs, and fix an x86-64 isel bug that this exposed. SUBREG_TO_REG for x86-64 implicit zero extension is only safe for isel to generate when the source is known to always have zeros in the high 32 bits. The EXTRACT_SUBREG instruction does not clear the high 32 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54444 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-06Re-introduce the 8-bit subreg zext-inreg patterns for x86-32,Dan Gohman
this time using MOV32to32_ and MOV16to16_. Thanks to Evan for suggesting this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54418 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-06Added support for fp callee saved registers.Bruno Cardoso Lopes
Added fp register clobbering during calls. Added AsmPrinter support for "fmask", a bitmask that indicates where on the stack the fp callee saved registers are. Fixed the stack frame layout for Mips, now the callee saved regs are in the right stack location (a little documentation about how this stack frame must look like is present in MipsRegisterInfo.cpp). This was done using the method MipsRegisterInfo::adjustMipsStackFrame To be more clear, these are examples of what is solves : 1) FP and RA are also callee saved, and despite they aren't in CSI they must be saved before the fp callee saved registers. 2) The ABI requires that local varibles are allocated before the callee saved register area, the opposite behavior from the default allocation. 3) CPU and FPU saved register area must be aligned independent of each other. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54403 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-04- Fix SelectionDAG to generate correct CFGs.Owen Anderson
- Add a basic machine-level dead block eliminator. These two have to go together, since many other parts of the code generator are unable to handle the unreachable blocks otherwise created. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54333 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-31Add a flag to disable jump table generation (allDale Johannesen
switches use the binary search algorithm) for environments that don't support it. PPC64 JIT is such an environment; turn the flag on for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54248 91177308-0d34-0410-b5e6-96231b3b80d8

access). Added pattern to match bitconvert node. Fixed MTC1 asm string bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54229 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-30Reapply r54147 with a constraint to only use the 8-bitDan Gohman
subreg form on x86-64, to avoid the problem with x86-32 having GPRs that don't have 8-bit subregs. Also, change several 16-bit instructions to use equivalent 32-bit instructions. These have a smaller encoding and avoid partial-register updates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54223 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-28Add x86 isel patterns to match what would be a ZERO_EXTEND_INREG operation,Dan Gohman
