2008-08-26Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy ↵Owen Anderson
requested was inserted or not. This allows bitcast in fast isel to properly handle the case where an appropriate reg-to-reg copy is not available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55375 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-23Move the point at which FastISel taps into the SelectionDAGISelDan Gohman
process up to a higher level. This allows FastISel to leverage more of SelectionDAGISel's infastructure, such as updating Machine PHI nodes. Also, implement transitioning from SDISel back to FastISel in the middle of a block, so it's now possible to go back and forth. This allows FastISel to hand individual CallInsts and other complicated things off to SDISel to handle, while handling the rest of the block itself. To help support this, reorganize the SelectionDAG class so that it is allocated once and reused throughout a function, instead of being completely reallocated for each block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55219 91177308-0d34-0410-b5e6-96231b3b80d8

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

2008-07-24Fix a catastrophic PPC64 ABI bug: i32 operands which are passed in memory ↵Evan Cheng
(all of the parameter registers are used) are loaded from sp offsets that were off by 4. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53979 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21Add VerifyNode, a place to put sanity checks onDuncan Sands
generic SDNode's (nodes with their own constructors should do sanity checking in the constructor). Add sanity checks for BUILD_VECTOR and fix all the places that were producing bogus BUILD_VECTORs, as found by "make check". My favorite is the BUILD_VECTOR with only two operands that was being used to build a vector with four elements! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53850 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-19Unbreak build: 'DarwinTargetAsmInfo' was already taken as PPC TAI flavour.Anton Korobeynikov

2008-07-19Make sure custom lowering for LegalizeTypesDuncan Sands
returns a node with the right number of return values. This fixes codegen of Generic/cast-fp.ll, Generic/fp_to_int.ll and PowerPC/multiple-return-values.ll when using -march=ppc32 -mattr=+64bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53794 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17Add a new function, ReplaceAllUsesOfValuesWith, which handles bulkDan Gohman
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

2008-07-08Make debug info come out in data-only files.Dale Johannesen
This is a question of the debugging setup code not being called at the right time, and it's called from target-dependent code for some reason. I have only attempted to fix Darwin, but I'm pretty sure it's broken elsewhere; I'll leave that to people who can test it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53254 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-07Pool-allocation for MachineInstrs, MachineBasicBlocks, andDan Gohman
MachineMemOperands. The pools are owned by MachineFunctions. This drastically reduces the number of calls to malloc/free made during the "Emit" phase of scheduling, as well as later phases in CodeGen. Combined with other changes, this speeds up the "instruction selection" phase of CodeGen by 10% in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53212 91177308-0d34-0410-b5e6-96231b3b80d8
