* Support the assume_aligned function attributeHal Finkel2014-09-264-63/+177
| | | | | | | | | In addition to __builtin_assume_aligned, GCC also supports an assume_aligned attribute which specifies the alignment (and optional offset) of a function's return value. Here we implement support for the assume_aligned attribute by making use of the @llvm.assume intrinsic. llvm-svn: 218500

* MS ABI: Avoid hashing back reference keys in manglerDavid Majnemer2014-09-251-17/+8
| | | | | | | | | | | | | | | | | | | | This patch replaces the back reference StringMap from the MS mangler with a SmallVector of strings. My previous patches reduced the number of hashes involved in back reference lookups, this one removes them completely. The back reference map contains at most 10 entries, which are likely to be of varying sizes and different initial subsequences, and which can easily became huge (due to templates and namespaces). The solution presented is the simplest possible one. Nevertheless, it's enough to reduce compilation times for a particular test case from 11.1s to 9s, versus 8.58s for the Itanium ABI. Possible further improvements include using a sorted vector (carefully to not introduce an extra comparison), storing the string contents in a common arena, and/or keep the string storage in the context for reuse.

* Fix handling of preincrement on bit-fields. This gives a bit-field in C++, butRichard Smith2014-09-242-7/+27
| | | | | | | | | | | we were failing to find that bit-field when performing integer promotions. This brings us closer to following the standard, and closer to GCC. In C, this change is technically a regression: we get bit-field promotions completely wrong in C, promoting cases that are categorically not bit-field designators. This change makes us do so slightly more consistently, though. llvm-svn: 218428
* clang-format: Don't let -style=Chromium imply c++03 template formatting.Nico Weber2014-09-241-1/+0
| | | | | | | Chromium's now using some c++11 language features, so it's now fine that clang-format produces vector<vector<int>>. llvm-svn: 218392
* Include debug info for types referenced only via explicit cast expressions.David Blaikie2014-09-243-0/+15
| | | | | | | | | | | | | | | | | | | | | | | Most of the debug info emission is powered essentially from function definitions - if we emit the definition of a function, we emit the types of its parameters, the members of those types, and so on and so forth. For types that aren't referenced even indirectly due to this - because they only appear in temporary expressions, not in any named variable, we need to explicitly emit/add them as is done here. This is not the only case of such code, and we might want to consider handling "void func(void*); ... func(new T());" (currently debug info for T is not emitted) at some point, though GCC doesn't. There's a much broader solution to these issues, but it's a lot of work for possibly marginal gain (but might help us improve the default -fno-standalone-debug behavior to be even more aggressive in some places). See the original review thread for more details. Patch by jyoti allur (jyoti.yalamanchili@gmail.com)! Differential Revision: http://reviews.llvm.org/D2498 llvm-svn: 218390

* MS ABI: Pure virtual functions don't contribute to vtordispsDavid Majnemer2014-09-231-14/+13
| | | | | | | | | | | Usually, overriding a virtual function defined in a virtual base required emission of a vtordisp slot in the record.

| | | | | | | | | | | | | | | | | | | Summary: Vectors are normally 16-byte aligned, however the O32 ABI enforces a maximum alignment of 8-bytes since the base of the stack is 8-byte aligned. Previously, this was enforced on the caller side, but not on the callee side. This fixes the output of OpenCL's printf when given vectors.

* Fix bugs in cpuid.h.Akira Hatanaka2014-09-201-15/+13
| | | | | | | | | | | | | | | This commit makes two changes: - Remove the push and pop instructions that were saving and restoring %ebx before and after cpuid in 32-bit pic mode. We were doing this to ensure we don't lose the GOT address in pic register %ebx, but this isn't necessary because the GOT address is kept in a virtual register. - In 64-bit mode, preserve base register %rbx around cpuid. This fixes PR20311 and rdar://problem/17686779. llvm-svn: 218173

System headers use prototype-less __stdcall functions, so make that a warning that's DefaultError -- then it fires on regular code but is suppressed in system headers. Since it's used in system headers, we have codegen tests for this; massage them slightly so that they still compile. llvm-svn: 218166
