* uselistorder: Update for LLVM API change in r234959Duncan P. N. Exon Smith2015-04-151-1/+3
| | | | | | | | Now that `addBitcodeWriterPass()` requires an explicit bit to preserve use-list order, send it in from `clang`. It looks like I'll be able to push this up to the `-cc1` options. llvm-svn: 234960
* Reland r234613 (and follow-ups 234614, 234616, 234618)Reid Kleckner2015-04-146-135/+194
| | | | | | | The frameescape intrinsic cannot be inlined, so I fixed the inliner in r234937. This should address PR23216. llvm-svn: 234942
* IR: Change clang to set -preserve-bc-uselistorderDuncan P. N. Exon Smith2015-04-141-0/+9
| | | | | | | | | | | | Change `clang` to set `-preserve-bc-uselistorder` for the driver options `-emit-llvm` and `-save-temps`. The former is useful for reproducing results from `clang` in `opt` or `llc`, while the latter prevents `-save-temps` from affecting the output. This is part of PR5680. `-preserve-bc-uselistorder=true` is currently on by default, but a follow-up commit in LLVM will reverse it. llvm-svn: 234920

* Add new warning -Wrange-loop-analysis to warn on copies during loops.Richard Trieu2015-04-131-0/+152
| | | | | | | | | | | | -Wrange-loop-analysis is a subgroup of -Wloop-analysis and will warn when a range-based for-loop makes copies of the elements in the range. If possible, suggest the proper type to prevent copies, or the non-reference to help distinguish copy versus non-copy forms. Existing warnings in -Wloop-analysis are moved to -Wfor-loop-analysis, also a subgroup of -Wloop-analysis. Differential Revision: http://reviews.llvm.org/D4169 llvm-svn: 234804

* NaCl ARM: fix assembler float abi flagsDerek Schuff2015-04-101-1/+2
| | | | | | | | | | | | | | | | | | Summary: tools::arm::getARMFloatABI() was falling back to guessing soft-float because it wasn't seeing the GNUEABIHF environment from ComputeEffectivClangTriple when it was called from gnutools::Assemble::ConstructJob. Fix by using the effective clang triple in gnutools::Assemble, which now matches the -triple flag used by cc1 and ClangAs jobs.

* Workaround a performance issue with modules + PCHBen Langmuir2015-04-101-1/+4
| | | | | | | | | | | | More fallout from r228234; when looking up an identifier in a PCH that imports the Cocoa module on Darwin, it was taking 2 to 5 seconds because we were hammering the MapVector::erase() function, which is O(n). For now, just clear() the contained SmallVector to get back to 0.25 - 0.5 seconds. This is probably not the long-term fix, because without modules or without PCH the performance is more like 0.02 seconds. llvm-svn: 234655

* [Frontend] Close open file handles before renaming output filesReid Kleckner2015-04-101-10/+12
| | | | | | | | | | | | The placement of the 'delete' call that was removed in the unique_ptr migration in r234597 was not an accident. The raw_ostream has to be destroyed before you do the rename on Windows, otherwise you get ERROR_ACCESS_DENIED. We can still use unique_ptr, we just need to do a manual reset().

* Remove threshold for inserting lifetime markers for named temporariesArnaud A. de Grandmaison2015-04-107-34/+100
| | | | | | | | | | | | | | | | | | | Now that TailRecursionElimination has been fixed with r222354, the threshold on size for lifetime marker insertion can be removed. This only affects named temporary though, as the patch for unnamed temporaries is still in progress. My previous commit (r222993) was not handling debuginfo correctly, but this could only be seen with some asan tests. Basically, lifetime markers are just instrumentation for the compiler's usage and should not affect debug information; however, the cleanup infrastructure was assuming it contained only destructors, i.e. actual code to be executed, and was setting the breakpoint for the end of the function to the closing '}', and not the return statement, in order to show some destructors have been called when leaving the function. This is wrong when the cleanups are only lifetime markers, and this is now fixed. llvm-svn: 234581
