2013-08-07Treat __sync_synchronize and asm("":::"memory") as stronger fences.JF Bastien
This is a companion patch to: https://codereview.chromium.org/22240002/ https://codereview.chromium.org/22474008/ and deals with the Clang-side of things. The above patch will handle the fallouts of this Clang patch, including some changes to un-duplicate work that RewriteAsmDirectives.cpp does. The goal of this patch is to force some extra ordering on non-atomics for le32 which LLVM doesn't necessarily provide.

Un-break the gdb buildbot. - Use the debug location of the return expression for the cleanup code if the return expression is trivially evaluatable, regardless of the number of stop points in the function. - Ensure that any EH code in the cleanup still gets the line number of the closing } of the lexical scope. - Added a testcase with EH in the cleanup. rdar://problem/13442648 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181056 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-03Move parsing of identifiers in MS-style inline assembly intoJohn McCall
the actual parser and support arbitrary id-expressions. We're actually basically set up to do arbitrary expressions here if we wanted to. Assembly operands permit things like A::x to be written regardless of language mode, which forces us to embellish the evaluation context logic somewhat. The logic here under template instantiation is incorrect; we need to preserve the fact that an expression was unevaluated. Of course, template instantiation in general is fishy here because we have no way of delaying semantic analysis in the MC parser. It's all just fishy. I've also fixed the serialization of MS asm statements. This commit depends on an LLVM commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180976 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-02Ensure that the line table for functions with cleanups is sequential.Adrian Prantl
If there is cleanup code, the cleanup code gets the debug location of the closing '}'. The subsequent ret IR-instruction does not get a debug location. The return _expression_ will get the debug location of the return statement. If the function contains only a single, simple return statement, the cleanup code may become the first breakpoint in the function. In this case we set the debug location for the cleanup code to the location of the return statement. rdar://problem/13442648 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180932 91177308-0d34-0410-b5e6-96231b3b80d8

CapturedStmt can be used to implement generic function outlining as described in http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-January/027540.html. CapturedStmt is not exposed to the C api.

2013-03-07Change hasAggregateLLVMType, which conflates complex andJohn McCall
aggregate types in a profoundly wrong way that has to be worked around in every call site, to getEvaluationKind, which classifies and distinguishes between all of these cases. Also, normalize the API for loading and storing complexes.

2013-01-26PR14566: Debug Info: avoid top level lexical blocks in functionsDavid Blaikie
One of the gotchas (see changes to CodeGenFunction) was due to the fix in r139416 (for PR10829). This only worked previously because the top level lexical block would set the location to the end of the function, the debug location would be updated (as per r139416), the location would be set to the end of the function again (but that would no-op, since it was the same as the previous location), then the return instruction would be emitted using the debug location. Once the top level lexical block was no longer emitted, the end-of-function location change was causing the debug loc to be updated, regressing that bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173593 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25During jump-scope checking, build an ExprWithCleanups immediatelyJohn McCall
into the enclosing scope; this is a more accurate model but is (I believe) unnecessary in my test case due to other flaws. However, one of those flaws is now intentional: blocks which appear in return statements can be trivially observed to not extend in lifetime past the return, and so we can allow a jump past them. Do the necessary magic in IR-generation to make this work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164589 91177308-0d34-0410-b5e6-96231b3b80d8
