Douglas Gregor 3ec6663be0 Back out my heinous hack that tricked the module generation mechanism 
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.

Douglas Gregor 232e3431e2 Split compiler builtin module into "stdlib" builtins and "intrinsic" 
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.

 2012-01-31 21:57:50 +00:00
Douglas Gregor 56435b49e0 Remove tgmath.h from the module map for now, because it currently causes a 
cyclic module dependency due to its inclusion of math.h and
complex.h. I'll take another shot at it later.

Craig Topper d6d3a05b4f Cleanup 3dnow builtin handling. Most of them were already handled by LLVM connecting intrinsics and builtins in IntrinsicsX86.td.

Douglas Gregor 0070c0bfbe Introduce TargetInfo::hasFeature() to query various feature names in 
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>.

Douglas Gregor 3f09de6442 Introduce a module map for (some of) the compiler-supplied 
headers. The remaining headers require more sophisticated
requirements; they'll be handled separately. Part of
<rdar://problem/10710060>.

Douglas Gregor 38f3981a99 On Darwin, use the system's <unwind.h> whenever it is 
available. Clang's <unwind.h> isn't ready for prime time. Fixes
