2001-11-12When allocating space on stack for writing a register,Vikram S. Adve
use the size of the register, not the size of the Value type, to get the right alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1284 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-12Bug fix in offset alignment computations: don't subtract the paddingVikram S. Adve
value from size *before* subtracting size from offset! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1283 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-12For phi elimination, now we are generating only one instructionRuchira Sasanka
using cpValue2Value instead of passing vector to createCopyInstructionByType. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1272 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-12Eliminate most uses of the machine instruction vector for each LLVM instr,Vikram S. Adve
since some m. instr. may be generated by LLVM instrs. in other blocks. Handle non-SSA (anti and output) edges and true edges uniformly by working with machine instructions alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1269 91177308-0d34-0410-b5e6-96231b3b80d8

2001-11-11Only add true dep. edges from an earlier to a later instruction.Vikram S. Adve
This wasn't a problem until we started putting copies for Phi values that produced cycles in the SchedGraph! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1254 91177308-0d34-0410-b5e6-96231b3b80d8
