* Add backend dignostic printer for unsupported featuresOliver Stannard2016-01-271-11/+64
| | | | | | | | | | | | | | The related LLVM patch adds a backend diagnostic type for reporting unsupported features, this adds a printer for them to clang. In the case where debug location information is not available, I've changed the printer to report the location as the first line of the function, rather than the closing brace, as the latter does not give the user any information. This also affects optimisation remarks. Differential Revision: http://reviews.llvm.org/D16591 llvm-svn: 258950
* [MS ABI] Allow a member pointers' converted type to changeDavid Majnemer2016-01-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Member pointers in the MS ABI are tricky for a variety of reasons. The size of a member pointer is indeterminate until the program reaches a point where the representation is required to be known. However, *pointers* to member pointers may exist without knowing the pointee type's representation. In these cases, we synthesize an opaque LLVM type for the pointee type. However, we can be in a situation where the underlying member pointer's representation became known mid-way through the program. To account for this, we attempted to manicure CodeGen's type-cache so that we can replace the opaque member pointer type with the real deal while leaving the pointer types unperturbed. This, unfortunately, is a problematic approach to take as we will violate CodeGen's invariants. These violations are mostly harmless but let's do the right thing instead: invalidate the type-cache if a member pointer's LLVM representation changes. This fixes PR26313. llvm-svn: 258839

* [ThinLTO] Leverage new in-place renaming supportTeresa Johnson2016-01-081-35/+1
| | | | | | | | | | | | Due to the new in-place renaming support added in r257174, we no longer need to invoke ThinLTO global renaming from clang. It will be invoked on the module in the FunctionImport pass (by an immediately following llvm commit). As a result, we don't need to load the FunctionInfoIndex as early, so that is moved down into EmitAssemblyHelper::EmitAssembly. llvm-svn: 257179

* [ThinLTO] Option to invoke ThinLTO backend passes and importingTeresa Johnson2015-12-071-21/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Adds new option -fthinlto-index=<file> to invoke the LTO pipeline along with function importing via clang using the supplied function summary index file. This supports invoking the parallel ThinLTO backend processes in a distributed build environment via clang. Additionally, this causes the module linker to be invoked on the bitcode file being compiled to perform any necessary promotion and renaming of locals that are exported via the function summary index file. Add a couple tests that confirm we get expected errors when we try to use the new option on a file that isn't bitcode, or specify an invalid index file. The tests also confirm that we trigger the expected function import pass.

* Allow linking multiple bitcode files.Artem Belevich2015-10-271-53/+61
| | | | | | | | | | | | | | | | | | Linking options for particular file depend on the option that specifies the file. Currently there are two: * -mlink-bitcode-file links in complete content of the specified file. * -mlink-cuda-bitcode links in only the symbols needed by current TU. Linked symbols are internalized. This bitcode linking mode is used to link device-specific bitcode provided by CUDA. Files are linked in order they are specified on command line. -mlink-cuda-bitcode replaces -fcuda-uses-libdevice flag. Differential Revision: http://reviews.llvm.org/D13913 llvm-svn: 251427

* Print vectorization analysis when loop hint is specified.Tyler Nowicki2015-08-111-15/+21
| | | | | | This patche and a related llvm patch solve the problem of having to explicitly enable analysis when specifying a loop hint pragma to get the diagnostics. Passing AlwasyPrint as the pass name (see below) causes the front-end to print the diagnostic if the user has specified '-Rpass-analysis' without an '=<target-pass>’. Users of loop hints can pass that compiler option without having to specify the pass and they will get diagnostics for only those loops with loop hints. llvm-svn: 244556
* Append options for vectorization when pointer checking threshold is exceeded.Tyler Nowicki2015-08-101-0/+19
| | | | | | Following one of the appended options will allow the loop to be vectorized. We do not include a command line option for modifying the pointer checking threshold because there is no clang-level interface for this currently. llvm-svn: 244526

* Fixed double-free in case of module loading error.Artem Belevich2015-05-121-2/+2
| | | | | | | | | | | | | GetOutputStream() owns the stream it returns pointer to and the pointer should never be freed by us. When we fail to load and exit early, unique_ptr still holds the pointer and frees it which leads to compiler crash when CompilerInstance attempts to free it again.
