* [x86] Additional small fix for MCU psABI supportAndrey Bokhanko2015-11-051-2/+6
| | | | | | | | This patch fixes one more thing in MCU psABI support: LongDoubleWidth should be set to 64. Differential Revision: http://reviews.llvm.org/D14285 llvm-svn: 252156
* [modules] If we're given a module file, via -fmodule-file=, for a module, butRichard Smith2015-11-051-5/+6
| | | | | | | | | we can't load that file due to a configuration mismatch, and implicit module building is disabled, and the user turns off the error-by-default warning for that situation, then fall back to textual inclusion for the module rather than giving an error if any of its headers are included. llvm-svn: 252114
* [x86] Front-end part of MCU psABI supportAndrey Bokhanko2015-11-021-1/+7
| | | | | | | | | | | This patch implements two things in front-end for MCU psABI support: 1) "long double type is the same as double." 2) "New predefined C/C++ pre-processor symbols: iamcu and iamcu__. Differential Revision: http://reviews.llvm.org/D14205 llvm-svn: 251786

* Watch and TV OS: wire up basic ABI choicesTim Northover2015-10-302-1/+7

* Fix the calling convention of Mingw64 long double valuesReid Kleckner2015-10-281-1/+7
| | | | | | | | | | GCC uses the x87DoubleExtended model for long doubles, and passes them indirectly by address through function calls. Also replace the existing mingw-long-double assembly emitting test with an IR-level test. llvm-svn: 251567

* Define weak and __weak to mean ARC-style weak references, even in MRC.John McCall2015-10-221-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, __weak was silently accepted and ignored in MRC mode. That makes this a potentially source-breaking change that we have to roll out cautiously. Accordingly, for the time being, actual support for __weak references in MRC is experimental, and the compiler will reject attempts to actually form such references. The intent is to eventually enable the feature by default in all non-GC modes. (It is, of course, incompatible with ObjC GC's interpretation of __weak.) If you like, you can enable this feature with -Xclang -fobjc-weak but like any -Xclang option, this option may be removed at any point, e.g. if/when it is eventually enabled by default. This patch also enables the use of the ARC __unsafe_unretained qualifier in MRC. Unlike __weak, this is being enabled immediately. Since variables are essentially __unsafe_unretained by default in MRC, the only practical uses are (1) communication and (2) changing the default behavior of by-value block capture. As an implementation matter, this means that the ObjC ownership qualifiers may appear in any ObjC language mode, and so this patch removes a number of checks for getLangOpts().ObjCAutoRefCount that were guarding the processing of these qualifiers. I don't expect this to be a significant drain on performance; it may even be faster to just check for these qualifiers directly on a type (since it's probably in a register anyway) than to do N dependent loads to grab the LangOptions. rdar://9674298 llvm-svn: 251041
* [coroutines] Add lexer support for co_await, co_yield, and co_return keywords.Richard Smith2015-10-221-1/+3
| | | | | | | Add -fcoroutines flag (just for -cc1 for now) to enable the feature. Early indications are that this will be part of -std=c++1z. llvm-svn: 250980

* Fix __ARM_FP value for sp-only FPUs with Half-precisionRichard Barton2015-10-211-1/+1
| | | | | | | | | The logic for parsing FP capabilities to set __ARM_FP was mistakenly removing the Half-Precision capability when handling fp-only-sp resulting in a value of 0x4. Section 6.5.1 of ACLE states that for such FP architectures the value should be 0x6 llvm-svn: 250888

* Further increase helfulness of assert messageRichard Barton2015-10-161-4/+1
| | | | | | | | | If you increase the number of diags of a particular type by one more than the number available you get the nice assert message. If you do it by two more than available you get the old non-helpful message. Combining the two makes sense I think. llvm-svn: 250546

* [VFS] Let the user decide if they want path normalization.Benjamin Kramer2015-10-121-16/+30
| | | | | | | | | | | | | | This is a more principled version of what I did earlier. Path normalization is generally a good thing, but may break users in strange environments, e. g. using lots of symlinks. Let the user choose and default it to on. This also changes adding a duplicated file into returning an error if the file contents are different instead of an assertion failure.

* [VFS] Don't try to be heroic with '.' in paths.Benjamin Kramer2015-10-121-8/+11
| | | | | | | Actually the only special path we have to handle is ./foo, the rest is tricky to get right so do the same thing as the existing YAML vfs here. llvm-svn: 250036
* [VFS] remove handling of '..' for now.Benjamin Kramer2015-10-121-2/+2
| | | | | | | | | This can fail badly if we're overlaying a real file system and there are symlinks there. Just keep the path as-is for now. This essentially reverts r249830. llvm-svn: 250021

* Handle sse turning on mmx, but no -mmx not turning off SSE.Eric Christopher2015-10-081-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rationale : // sse3 __m128d test_mm_addsub_pd(__m128d A, __m128d B) { return _mm_addsub_pd(A, B); } // mmx void shift(__m64 a, __m64 b, int c) { _mm_slli_pi16(a, c); _mm_slli_pi32(a, c); _mm_slli_si64(a, c); _mm_srli_pi16(a, c); _mm_srli_pi32(a, c); _mm_srli_si64(a, c); _mm_srai_pi16(a, c); _mm_srai_pi32(a, c); } clang -msse3 -mno-mmx file.c -c For this code we should be able to explicitly turn off MMX without affecting the compilation of the SSE3 function and then diagnose and error on compiling the MMX function. This is a preparatory patch to the actual diagnosis code which is coming in a future patch. This sets us up to have the correct information where we need it and verifies that it's being emitted for the backend to handle. llvm-svn: 249733

* Simplify DefaultCPU in ARMTargetInfoRenato Golin2015-10-081-19/+11
| | | | | | | | | | | | | | | | | | Simplifying the convoluted CPU handling in ARMTargetInfo. The default base CPU on ARM is ARM7TDMI, arch ARMv4T, and ARMTargetInfo had a different one. This wasn't visible from Clang because the driver selects the defaults and sets the Arch/CPU features directly, but the constructor depended on the CPU, which was never used. This patch corrects the mistake and greatly simplifies how CPU is dealt with (essentially by removing the duplicated DefaultCPU field). Tests updated. llvm-svn: 249699
