2010-04-04fix an ugly wart in the MCInstPrinter api where theChris Lattner
raw_ostream to print an instruction to had to be specified at MCInstPrinter construction time instead of being able to pick at each call to printInstruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100307 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-04change a ton of code to not implicitly use the "O" raw_ostreamChris Lattner
member of AsmPrinter. Instead, pass it in explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100306 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-04Reapply address space patch after fixing an issue in MemCopyOptimizer.Mon P Wang
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset, e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100304 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-03asmstreamerize the .size directive for function bodies, force clientsChris Lattner
of printOffset to pass in a stream to print to. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100296 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-03add a twine form of MCStreamer::EmitRawText, and mc'izeChris Lattner
a few more things in AsmPrinter.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100294 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-03start moving towards emitting inline asm statements with Chris Lattner
EmitInlineAsm. However, this attempt is foiled by operands being emitted directly to "O" so I'll have to do some surgery and finish MCizing the world. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100291 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-03add a new EmitInlineAsm function to asmprinter to handle inline asm.Chris Lattner
If we have an MCAsmStreamer, we continue to emit asm textually, otherwise we (currently) emit an error to errs and ignore it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100289 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02Ok, third time's the charm. No changes from last time except the CMakeDavid Greene
source addition. Apparently the buildbots were wrong about failures. --- 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@100249 91177308-0d34-0410-b5e6-96231b3b80d8

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

2010-04-02Revert 100204. It broke a bunch of tests and apparently changed what passes ↵Evan Cheng

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.

2010-04-01Fix sdisel memcpy, memset, memmove lowering:Evan Cheng
1. Makes it possible to lower with floating point loads and stores. 2. Avoid unaligned loads / stores unless it's fast. 3. Fix some memcpy lowering logic bug related to when to optimize a load from constant string into a constant. 4. Adjust x86 memcpy lowering threshold to make it more sane. 5. Fix x86 target hook so it uses vector and floating point memory ops more effectively. rdar://7774704 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100090 91177308-0d34-0410-b5e6-96231b3b80d8
