2009-08-07Improve disabling of X86 AsmMatcher.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78381 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-07Disable X86 AsmMatcher for now, it is causing gcc-4.0 to run out of memory onDaniel Dunbar
i386-apple-darwin9. This presumably will get fixed once the generated code improves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-07llvm-mc/AsmMatcher: Move to a slightly more sane matching design.Daniel Dunbar
- Still not very sane, but a least its not 60k lines on X86. :) - In terms of correctness, currently some things are hard wired for X86, and we still don't properly resolve ambiguities (this is ignoring the instructions we don't even match due to funny .td stuff or other corner cases). The high level changes: 1. Represent tokens which are significant for matching explicitly as separate operands. This uniformly handles not only the instruction mnemonic, but also 'signficiant' syntax like the '*' in "call * ...". 2. Separate the matching of operands to an instruction from the construction of the MCInst. In theory this can be done during matching, but since the number of variations is small I think it makes sense to decompose the problems. 3. Improved a few of the mechanisms to at least successfully flatten / tokenize the assembly strings for PowerPC and ARM. 4. The comment at the top of AsmMatcherEmitter.cpp explains the approach I'm moving towards for handling ambiguous instructions. The high-bit is to infer a partial ordering of the operand classes (and force the user to specify one if we can't) and use that to resolve ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78378 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-31llvm-mc: A few more parsing / match tweaks.Daniel Dunbar
- Operands which are just a label should be parsed as immediates, not memory operands (from the assembler perspective). - Match a few more flavors of immediates. - Distinguish match functions for memory operands which don't take a segment register. - We match the .s for "hello world" now! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77745 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-31llvm-mc: Match a few X86 instructions.Daniel Dunbar
- This is "experimental" code, I am feeling my way around and working out the best way to do things (and learning tblgen in the process). Comments welcome, but keep in mind this stuff will change radically. - This is enough to match "subb" and friends, but not much else. The next step is to automatically generate the matchers for individual operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77657 91177308-0d34-0410-b5e6-96231b3b80d8
