2004-09-02We don't need to sort the added vector as unhandled intervals areAlkis Evlogimenos
stored in a binary heap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16143 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-01Changes For Bug 352Reid Spencer
Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-01Be a bit more efficient when processing the active and inactiveAlkis Evlogimenos
lists. Instead of scanning the vector backwards, scan it forward and swap each element we want to erase. Then at the end erase all removed intervals at once. This doesn't save much: 0.08s out of 4s when compiling 176.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16136 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-24Fix a bug in a previous checkin of mine, correctingChris Lattner
Regression.CodeGen.Generic.2004-04-09-SameValueCoalescing.llx and the code size problem. This bug prevented us from doing most register coallesces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16031 91177308-0d34-0410-b5e6-96231b3b80d8
2004-08-24Do not use .xword and friends to emit zeros on V9. Apparently there are issuesChris Lattner
with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the same as 8 .byte 0's). Because we do not know when or when we are not aligned, just emit bytes like the old V9 asmprinter did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16006 91177308-0d34-0410-b5e6-96231b3b80d8
