2012-04-24Expand #include_next in float.h from mingw to _msc_ver.Nico Weber
A test for this is checking if this compiles: #include <float.h> inline bool IsFinite(const double& number) { return _finite(number) != 0; } That depends however on either mingw or msvc being installed, and chapuni tells me there might be issues with float.h on mingw, so no automated test is added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155507 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-20Add 3dNOW intrinsic header to x86intrin.h, conditioned on __3dNOW__ toChandler Carruth
match the behavior of GCC. Also add a test for these intrinsics, which apparently have *zero* tests. =[ Not surprisingly, Clang crashed when compiling these. Fix the bug in CodeGen where we failed to bitcast the argument type to x86mmx prior to calling the LLVM intrinsic. This fixes an assert on the new 3dnow-builtins.c test. This is one issue impacting the efforts to get Clang to emulate the Microsoft intrinsics headers -- 3dnow intrinsics are implictitly made available there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150948 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
2012-01-31Split 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

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.
