* Convert uses of std::vector in TargetInstrInfo to SmallVector. This change ↵Owen Anderson2008-08-142-8/+8
| | | | | | had to be propoagated down into all the targets and up into all clients of this API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54802 91177308-0d34-0410-b5e6-96231b3b80d8
* Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT nodeBruno Cardoso Lopes2008-08-135-76/+127
| | | | | | | | | | | | | | | | | 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

* 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

* Add a new function, ReplaceAllUsesOfValuesWith, which handles bulkDan Gohman2008-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | replacement of multiple values. This is slightly more efficient than doing multiple ReplaceAllUsesOfValueWith calls, and theoretically could be optimized even further. However, an important property of this new function is that it handles the case where the source value set and destination value set overlap. This makes it feasible for isel to use SelectNodeTo in many very common cases, which is advantageous because SelectNodeTo avoids a temporary node and it doesn't require CSEMap updates for users of values that don't change position. Revamp MorphNodeTo, which is what does all the work of SelectNodeTo, to handle operand lists more efficiently, and to correctly handle a number of corner cases to which its new wider use exposes it. This commit also includes a change to the encoding of post-isel opcodes in SDNodes; now instead of being sandwiched between the target-independent pre-isel opcodes and the target-dependent pre-isel opcodes, post-isel opcodes are now represented as negative values. This makes it possible to test if an opcode is pre-isel or post-isel without having to know the size of the current target's post-isel instruction set. These changes speed up llc overall by 3% and reduce memory usage by 10% on the InstructionCombining.cpp testcase with -fast and -regalloc=local. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53728 91177308-0d34-0410-b5e6-96231b3b80d8
