Bruno Cardoso Lopes	d738f1e6c7	Several changes to Mips backend, experimental fp support being the most ... 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. llvm-svn: 53146	2008-07-05 19:05:21 +00:00
Bruno Cardoso Lopes	5a4d1d0fd3	Some Mips minor fixes ... Added support for mips little endian arch => mipsel llvm-svn: 51923	2008-06-04 01:45:25 +00:00
Dan Gohman	bab18cae46	Clean up the use of static and anonymous namespaces. This turned up ... several things that were neither in an anonymous namespace nor static but not intended to be global. llvm-svn: 51017	2008-05-13 00:00:25 +00:00
Dan Gohman	8e3c88c4e9	Use PassManagerBase instead of FunctionPassManager for functions ... that merely add passes. This allows them to be used with either FunctionPassManager or PassManager, or even with a custom new kind of pass manager. llvm-svn: 48256	2008-03-11 22:29:46 +00:00
Chris Lattner	ad9a6ccb83	Remove attribution from file headers, per discussion on llvmdev. ... llvm-svn: 45418	2007-12-29 20:36:04 +00:00
Bruno Cardoso Lopes	569b5512b0	Added support for PIC code with "explicit relocations" *only*. ... Removed all macro code for PIC (goodbye "la"). Support tested with shootout bench. llvm-svn: 43697	2007-11-05 03:02:32 +00:00
Bruno Cardoso Lopes	627ba10946	Position Independent Code (PIC) support [2] ... - Added a function to hold the stack location where GP must be stored during LowerCALL - AsmPrinter now emits directives based on relocation type - PIC_ set to default relocation type (same as GCC) llvm-svn: 42779	2007-10-09 03:01:19 +00:00
Bruno Cardoso Lopes	ff764398e6	Added method to get Mips register numbers ... Changed the stack frame layout, StackGrowsUp fits better to Mips strange stack. Stack offset calculation bug fixed! llvm-svn: 41529	2007-08-28 05:13:42 +00:00
Bruno Cardoso Lopes	ae01dc5e74	createMipsDelaySlotFillerPass added to mips codegen runtime ... llvm-svn: 41154	2007-08-18 01:58:15 +00:00
Bruno Cardoso Lopes	0ba66ea1dc	Now that stack is represented the right way, LOA starts at 0 ... llvm-svn: 39761	2007-07-11 23:17:41 +00:00
Chris Lattner	4810c53b05	The various "getModuleMatchQuality" implementations should return ... zero if they see a target triple they don't understand. llvm-svn: 38463	2007-07-09 17:25:29 +00:00
Bruno Cardoso Lopes	709699b8d3	Initial Mips support, here we go! =) ... - 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. llvm-svn: 37461	2007-06-06 07:42:06 +00:00
