2004-08-29Revise the design of the Path concept per peer review. Too many changes toReid Spencer
note individually but these essence of it is to not derive from std::string, clarify the interface, and provide better documentation. There is now also (untested) implementations for AIX, Darwin, and SunOS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16078 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-26Add the CompactionTableIsEmpty function so that we can determine if aReid Spencer
CompactionTable really needs to be emitted. This is not a straight forward computation, hence the need for a member function here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16062 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

2004-08-24This code is dodgy, but the guaranteed assertion failure doesn't help anything.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16014 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

2004-08-21Initial checkin of a pass to lower packed operations to scalars operations.Reid Spencer
This also registers the pass with opt with a -lower-packed command line option. Patch contributed by Brad Jones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15987 91177308-0d34-0410-b5e6-96231b3b80d8
2004-08-21Bytecode Analyzer Cleanup:Reid Spencer
- Rearrange output order to make more sense - Make only the function level output count as "detailed" - Output dump output directly to stream, don't buffer it. - Fix counting of block sizes - Implement new handlers for number of types, dependent libs, target triple - Compute the size of block headers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15985 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-21Two Changes:Reid Spencer
- Pass the output stream to the analyzer so it can write its output there directly instead of buffering it. - Don't pass a boolean to ParseBytecode because its not needed any more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15983 91177308-0d34-0410-b5e6-96231b3b80d8
