2013-04-19Avoid names like __in that conflict with SAL in builtin headersReid Kleckner
Microsoft's Source Annotation Language (SAL) defines a bunch of keywords for annotating the inputs and outputs of functions. Empty definitions for the keywords are provided by <stdlib.h> -> <crtdefs.h> -> <sal.h>. This makes it basically impossible to include MSVC's stdlib.h and Clang's *mmintrin.h headers at the same time if they have variables named __in. As a workaround, I've renamed those variables. This fixes the Modules/compiler_builtins.m test which was XFAILed, presumably due to this conflict. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179860 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-11Use @import rather than @__experimental_modules_import, since theDouglas Gregor
latter is rather a mess to type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169919 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-05Make cpuid.h actually work with -std=c99 <rdar://problem/12552716>.Douglas Gregor
While we're here, extend the module map to cover most of the newly-added instrinsic headers. Only wmmintrin.h is missing, because it needs to be split into AES/PCLMUL subheaders (as a separate commit). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167398 91177308-0d34-0410-b5e6-96231b3b80d8

commit to a particular syntax for modules, and don't have time to push it forward in the near future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151841 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-02Back out my heinous hack that tricked the module generation mechanismDouglas Gregor
into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149611 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01test/Modules/compiler_builtins.m: Appease Cygwin to add -D__need_wint_t.NAKAMURA Takumi
On Cygwin, at first, <stddef.h> is included without __need_wint_t. Next, <stddef.h> is included with __need_wint_t, though Modules feature would not process <stddef.h> twice. Then, wint_t is not found in system headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149500 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-31Split compiler builtin module into "stdlib" builtins and "intrinsic"Douglas Gregor
builds, and bring mm_alloc.h into the fold. Start playing some tricks with these builtin modules to mirror the include_next tricks that the headers already perform. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149434 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-30Remove tgmath.h from the module map for now, because it currently causes aDouglas Gregor
cyclic module dependency due to its inclusion of math.h and complex.h. I'll take another shot at it later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149283 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-30Introduce TargetInfo::hasFeature() to query various feature names inDouglas Gregor
each of the targets. Use this for module requirements, so that we can pin the availability of certain modules to certain target features, e.g., provide a module for xmmintrin.h only when SSE support is available. Use these feature names to provide a nearly-complete module map for Clang's built-in headers. Only mm_alloc.h and unwind.h are missing, and those two are fairly specialized at the moment. Finishes <rdar://problem/10710060>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149227 91177308-0d34-0410-b5e6-96231b3b80d8
