* Re-enable elimination of unnecessary SUBREG_TO_REG instructions inDan Gohman2008-08-075-12/+46
| | | | | | | | | | | | 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

I didn't introduce this and I'm not attempting to fix it here, but it is more likely to be hit now since we're putting more stuff in the buffer.

* Added support for fp callee saved registers.Bruno Cardoso Lopes2008-08-066-152/+225
| | | | | | | | | | | | | | | | | | | | | | 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
