2010-04-02Second try of initial ARM/Thumb disassembler check-in. It consists of a tablgenJohnny Chen
backend (ARMDecoderEmitter) which emits the decoder functions for ARM and Thumb, and the disassembler core which invokes the decoder function and builds up the MCInst based on the decoded Opcode. Reviewed by Chris Latter and Bob Wilson. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100233 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02Separate out the AES-NI instructions from the SSE4.2 instructions. AddEric Christopher

2010-04-02Switch the code generator (except the JIT) onto the new DebugLocChris Lattner
representation. This eliminates the 'DILocation' MDNodes for file/line/col tuples from -O0 -g codegen. This remove the old DebugLoc class, making it a typedef for DebugLoc, I'll rename NewDebugLoc next. I didn't update the JIT to use the new apis, so it will continue to work, but be as slow as before. Someone should eventually do this or, better yet, rip out the JIT debug info stuff and build the JIT on top of MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100209 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02Let's try this again. Re-apply 100143 including an apparent missingDavid Greene
<string> include. For some reason the buildbot choked on this while my builds did not. It's probably due to a difference in system headers. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100204 91177308-0d34-0410-b5e6-96231b3b80d8
