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.

2013-01-17Provide a place for targets to insert ILP optimization passes.Jakob Stoklund Olesen
Move the early if-conversion pass into this group. ILP optimizations usually need to find the right balance between register pressure and ILP using the MachineTraceMetrics analysis to identify critical paths and estimate other costs. Such passes should run together so they can share dominator tree and loop info analyses. Besides if-conversion, future passes to run here here could include expression height reduction and ARM's MLxExpansion pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172687 91177308-0d34-0410-b5e6-96231b3b80d8
