2013-01-21Now that the inline cost analysis is a pass, we can easily have itChandler Carruth
depend on and use other analyses (as long as they're either immutable passes or CGSCC passes of course -- nothing in the pass manager has been fixed here). Leverage this to thread TargetTransformInfo down through the inline cost analysis. No functionality changed here, this just threads things through. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173031 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-21Make the inline cost a proper analysis pass. This remains essentiallyChandler Carruth
a dynamic analysis done on each call to the routine. However, now it can use the standard pass infrastructure to reference other analyses, instead of a silly setter method. This will become more interesting as I teach it about more analysis passes. This updates the two inliner passes to use the inline cost analysis. Doing so highlights how utterly redundant these two passes are. Either we should find a cheaper way to do always inlining, or we should merge the two and just fiddle with the thresholds to get the desired behavior. I'm leaning increasingly toward the latter as it would also remove the Inliner sub-class split. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173030 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21Introduce a generic interface for querying an operation's expectedChandler Carruth
lowered cost. Currently, this is a direct port of the logic implementing isInstructionFree in CodeMetrics. The hope is that the interface can be improved (f.ex. supporting un-formed instruction queries) and the implementation abstracted so that as we have test cases and target knowledge we can expose increasingly accurate heuristics to clients. I'll start switching existing consumers over and kill off the routine in CodeMetrics in subsequent commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172998 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-18This is a resubmittal. For some reason it broke the bots yesterdayJack Carter
but I cannot reproduce the problem and have scrubed my sources and even tested with llvm-lit -v --vg. Support for Mips register information sections. Mips ELF object files have a section that is dedicated to register use info. Some of this information such as the assumed Global Pointer value is used by the linker in relocation resolution. The register info file is .reginfo in o32 and .MIPS.options in 64 and n32 abi files. This patch contains the changes needed to create the sections, but leaves the actual register accounting for a future patch.

2013-01-17Reverting r171325 & r172363. This was causing a mis-compile on the ↵Bill Wendling
self-hosted LTO build bots. Okay, here's how to reproduce the problem: 1) Build a Release (or Release+Asserts) version of clang in the normal way. 2) Using the clang & clang++ binaries from (1), build a Release (or Release+Asserts) version of the same sources, but this time enable LTO --- specify the `-flto' flag on the command line. 3) Run the ARC migrator tests: $ arcmt-test --args -triple x86_64-apple-darwin10 -fsyntax-only -x objective-c++ ./src/tools/clang/test/ARCMT/cxx-rewrite.mm You'll see that the output isn't correct (the whitespace is off). The mis-compile is in the function `RewriteBuffer::RemoveText' in the clang/lib/Rewrite/Core/Rewriter.cpp file. When that function and RewriteRope.cpp are compiled with LTO and the `arcmt-test' executable is regenerated, you'll see the error. When those files are not LTO'ed, then the output of the `arcmt-test' is fine. It is *really* hard to get a testcase out of this. I'll file a PR with what I have currently. --- Reverse-merging r172363 into '.': U include/llvm/Analysis/MemoryBuiltins.h U lib/Analysis/MemoryBuiltins.cpp --- Reverse-merging r171325 into '.': U test/Transforms/InstCombine/objsize.ll G include/llvm/Analysis/MemoryBuiltins.h G lib/Analysis/MemoryBuiltins.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172756 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-17Skeleton for pass-based bitcode ABI verifierDerek Schuff
This is the skeleton for a verifier for the portion of the PNaCl bitcode ABI that can be verified after the bitcode has been read into a Module object. There is a ModulePass for module-level rules (e.g. GV linkage types) and a FunctionPass for rules that apply to function bodies (e.g. legal instructions). They are separated this way to keep the verifier streaming-friendly. For now, the passes are registered but not hooked up, so they can only be run manually via opt. There are 2 bits of actual functionality, just so each pass has something to do: The ModulePass checks the linkage types of GVs, and the FunctionPass checks instruction opcodes. For now only the terminator instructions are checked, but the idea is to add the rest of the allowed instructions to the whitelist, and possibly call operand checks from the switch statement as well. For now we just print messagees to stderr, but we will probably want a better way to plumb the errors in the browser in the future.
