| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | does. Enhance the X86 asmparser to produce ranges in the one case that was annoying me, for example: test.s:10:15: error: invalid operand for instruction movl 0(%rax), 0(%edx) ^~~~~~~ It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use ranges where appropriate if someone is interested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142106 91177308-0d34-0410-b5e6-96231b3b80d8
| * Add a bad char heuristic to StringRef::find.Benjamin Kramer2011-10-151-3/+26
| | | | | | | | | | | | | | | | | | Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways. The worst case is still O(n*m) but we do a lot better on the average case now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142061 91177308-0d34-0410-b5e6-96231b3b80d8

| * One more patch towards JIT support for Mips.Bruno Cardoso Lopes2011-09-141-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add TSFlags for the instruction formats. The idea here is to use as much encoding as possible from getBinaryCodeForInstr, and having TSFLags formats for that would make it easier to encode most part of the instructions (since Mips encodings are pretty straightforward) - Improve the mips mechanism for compilation callback - Add Mips specific code for invalidating the instruction cache - Next patch will address wrong tablegen encoding Commit msg added by my own but the patch is from Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139688 91177308-0d34-0410-b5e6-96231b3b80d8
