* Fixed Bug 2751Bruno Cardoso Lopes2008-09-151-3/+3
| | | | | | | | | | | | | http://llvm.org/bugs/show_bug.cgi?id=2751 Abicall was enabled even when static code model was provided in the command line. The correct behavior is to disable abicall when static is specified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56228 91177308-0d34-0410-b5e6-96231b3b80d8
* Make option variables static, so they won't cause nameclashAnton Korobeynikov2008-08-221-7/+10

* Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT nodeBruno Cardoso Lopes2008-08-131-0/+2
| | | | | | | | | | | | | | | | | is lowered properly and covers everything LowerSELECT_CC did. Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This avoid the ugly instruction by instruction checking in printOperand. Added a swap instruction present in the allegrex core. Added two conditional instructions present in the allegrex core : MOVZ and MOVN. They both allow a more efficient SELECT operation for integers. Also added SELECT patterns to optimize MOVZ and MOVN usage. The brcond and setcc patterns were cleaned: redundant and suboptimal patterns were removed. The suboptimals were replaced by more efficient ones. Fixed some instructions that were using immZExt16 instead of immSExt16. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54724 91177308-0d34-0410-b5e6-96231b3b80d8
* Support added for ctlz intrinsic, test case added.Bruno Cardoso Lopes2008-08-081-0/+1

* Match raw "psp" triple target, as done by the homebrew toolchain.Bruno Cardoso Lopes2008-08-081-1/+2

* Added initial support for small sections on Mips.Bruno Cardoso Lopes2008-07-211-0/+6
| | | | | | | | Added gp_rel relocations to support addressing small section contents. Added command line to specify small section threshold in bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53869 91177308-0d34-0410-b5e6-96231b3b80d8
* Added Subtarget support into RegisterInfoBruno Cardoso Lopes2008-07-141-2/+22
| | | | | | | | | | | | | | Added HasABICall and HasAbsoluteCall (equivalent to gcc -mabicall and -mno-shared). HasAbsoluteCall is not implemented but HasABICall is the default for o32 ABI. Now, both should help into a more accurate relocation types implementation. Added IsLinux is needed to choose between asm directives. Instruction name strings cleanup. AsmPrinter improved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53551 91177308-0d34-0410-b5e6-96231b3b80d8

* Several changes to Mips backend, experimental fp support being the mostBruno Cardoso Lopes2008-07-051-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | important. - Cleanup in the Subtarget info with addition of new features, not all support yet, but they allow the future inclusion of features easier. Among new features, we have : Arch family info (mips1, mips2, ...), ABI info (o32, eabi), 64-bit integer and float registers, allegrex vector FPU (VFPU), single float only support. - TargetMachine now detects allegrex core. - Added allegrex (Mips32r2) sext_inreg instructions. - *Added Float Point Instructions*, handling single float only, and aliased accesses for 32-bit FPUs. - Some cleanup in FP instruction formats and FP register classes. - Calling conventions improved to support mips 32-bit EABI. - Added Asm Printer support for fp cond codes. - Added support for sret copy to a return register. - EABI support added into LowerCALL and FORMAL_ARGS. - MipsFunctionInfo now keeps a virtual register per function to track the sret on function entry until function ret. - MipsInstrInfo FP support into methods (isMoveInstr, isLoadFromStackSlot, ...), FP cond codes mapping and initial FP Branch Analysis. - Two new Mips SDNode to handle fp branch and compare instructions : FPBrcond, FPCmp - MipsTargetLowering : handling different FP classes, Allegrex support, sret return copy, no homing location within EABI, non 32-bit stack objects arguments, and asm constraint for float. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53146 91177308-0d34-0410-b5e6-96231b3b80d8

- Modifications from the last patch included (issues pointed by Evan Cheng are now fixed). - Added more MipsI instructions. - Added more patterns to match branch instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37461 91177308-0d34-0410-b5e6-96231b3b80d8
