2013-03-16Exploit this-return of a callsite in a this-return function.Manman Ren
For constructors/desctructors that return 'this', if there exists a callsite that returns 'this' and is immediately before the return instruction, make sure we are using the return value from the callsite. We don't need to keep 'this' alive through the callsite. It also enables optimizations in the backend, such as tail call optimization. rdar://12818789 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177211 91177308-0d34-0410-b5e6-96231b3b80d8

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. I'm working on a larger patch and wanted to pull these changes out, but it would have be annoying to detangle them from each other. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176656 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-28Use the actual ABI-determined C calling convention for runtimeJohn McCall
calls and declarations. LLVM has a default CC determined by the target triple. This is not always the actual default CC for the ABI we've been asked to target, and so we sometimes find ourselves annotating all user functions with an explicit calling convention. Since these calling conventions usually agree for the simple set of argument types passed to most runtime functions, using the LLVM-default CC in principle has no effect. However, the LLVM optimizer goes into histrionics if it sees this kind of formal CC mismatch, since it has no concept of CC compatibility. Therefore, if this module happens to define the "runtime" function, or got LTO'ed with such a definition, we can miscompile; so it's quite important to get this right. Defining runtime functions locally is quite common in embedded applications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176286 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-17Re-apply r174919 - smarter copy/move assignment/construction, with fixes forLang Hames
bitfield related issues. The original commit broke Takumi's builder. The bug was caused by bitfield sizes being determined by their underlying type, rather than the field info. A similar issue with bitfield alignments showed up on closer testing. Both have been fixed in this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175389 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-11When generating IR for default copy-constructors, copy-assignment operators,Lang Hames
move-constructors and move-assignment operators, use memcpy to copy adjacent POD members. Previously, classes with one or more Non-POD members would fall back on element-wise copies for all members, including POD members. This often generated a lot of IR. Without padding metadata, it wasn't often possible for the LLVM optimizers to turn the element-wise copies into a memcpy. This code hasn't yet received any serious tuning. I didn't see any serious regressions on a self-hosted clang build, or any of the nightly tests, but I think it's important to get this out in the wild to get more testing. Insights, feedback and comments welcome. Many thanks to David Blaikie, Richard Smith, and especially John McCall for their help and feedback on this work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174919 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Fix exception handling line table problems introduced by r173593David Blaikie
r173593 made us a little too eager to associate all code at the end of a function with the user-written 'return' line. This caused problems with breakpoints as they'd be set in exception handling code preceeding the actual non-exception return handling code, leading to the breakpoint never being hit in non-exceptional execution. This change restores the pre-r173593 exception handling line information where the cleanup code is associated with the '}' not the return line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174206 91177308-0d34-0410-b5e6-96231b3b80d8
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
