// This test verifies that the correct macros are predefined.

Updated the test so that it checks for ms-compatibility in addition to ms-extensions. llvm-svn: 152516

No longer defining GNUC mode when compiling for Microsoft compatibility. This allows people's cross-platform compiler-specific macros to work properly. llvm-svn: 152512

Define __FINITE_MATH_ONLY__ based on -ffast-math and -ffinite-math-only. This macro was being unconditionally set to zero, preceded by a FIXME comment. This fixes <rdar://problem/11845441>. Patch by Michael Gottesman! llvm-svn: 160491
