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

(clang r149497 / llvm r149498) Also include the config.h header after all other headers, per the LLVM coding standards.

2012-02-01constexpr: check for overflow in pointer subtraction.Richard Smith
This is a mess. According to the C++11 standard, pointer subtraction only has undefined behavior if the difference of the array indices does not fit into a ptrdiff_t. However, common implementations effectively perform a char* subtraction first, and then divide the result by the element size, which can cause overflows in some cases. Those cases are not considered to be undefined behavior by this change; perhaps they should be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149490 91177308-0d34-0410-b5e6-96231b3b80d8
