2006-03-18Change the structure of lowering vector stuff. Note: This breaks someChris Lattner
things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26840 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-17Remove BRTWOWAY*Nate Begeman
Make the PPC backend not dependent on BRTWOWAY_CC and make the branch selector smarter about the code it generates, fixing a case in the readme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26814 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-10Added a parameter to control whether Constant::getStringValue() would chopEvan Cheng
off the result string at the first null terminator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26704 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-10Simplify the interface to the schedulers, to not pass the selected heuristicin.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26692 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-09remove dbg_declare, it's not used yet.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26659 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-08Get rid of the multiple copies of getStringValue. Now a Constant:: method.Jim Laskey
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26616 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-08Change the interface for getting a target HazardRecognizer to be more clean.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26608 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-06Hoist the HazardRecognizer out of the ScheduleDAGList.cpp file to whereChris Lattner
targets can implement them. Make the top-down scheduler non-g5-specific. Remove the old testing hazard recognizer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26569 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-05Split the list scheduler into top-down and bottom-up pieces. The priorityChris Lattner
function of the top-down scheduler are completely bogus currently, and having (future) PPC specific in this file is also wrong, but this is a small incremental step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26552 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-03Split memcpy/memset/memmove intrinsics into i32/i64 versions, resolvingChris Lattner
PR709, and paving the way for future progress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26476 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-23Fix an endianness problem on big-endian targets with expanded operandsChris Lattner
to inline asms. Mark some methods const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26334 91177308-0d34-0410-b5e6-96231b3b80d8

several bugs in inline asm expanded operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26332 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-22This fixes a couple of problems with expansionChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26318 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-22Change a whole bunch of code to be built around RegsForValue instead ofChris Lattner
a single register number. This fully implements promotion for inline asms, expand is close but not quite right yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26316 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-16Dumb bug. Code sees a memcpy from X+c so it increments src offset. But itEvan Cheng
turns out not to point to a constant string but it forgot change the offset back. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26242 91177308-0d34-0410-b5e6-96231b3b80d8
2006-02-16If the false case is the current basic block, then this is a self loop.Evan Cheng
We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra instruction in the loop. Instead, invert the condition and emit "Loop: ... br!cond Loop; br Out. Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26231 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-02Implement matching constraints. We can now say things like this:Chris Lattner
%C = call int asm "xyz $0, $1, $2, $3", "=r,r,r,0"(int %A, int %B, int 4) and get: xyz r2, r3, r4, r2 note that the r2's are pinned together.

2006-02-01Implement simple register assignment for inline asms. This allows us to ↵Chris Lattner
