* Speed up INT_MULTIPLY_WRAPV on macOSPaul Eggert2019-08-272-5/+19
| | | | | | | | | | Assume that __builtin_mul_overflow works OK with Clang on macOS. Mattias Engdegård says it’s safe to assume the relevant library is always available there. * lib/intprops.h (_GL_HAS___builtin_mul_overflow): New temporary internal macro. (_GL_HAS_BUILTIN_MUL_OVERFLOW): No need to work around the Clang bug on macOS.
* intprops.h, verify.h: port better to clangPaul Eggert2019-08-253-42/+103
| | | | | | | | | | | | | | | | | | | | | | | Improve code generated by INT_ADD_WRAPV and INT_SUBTRACT_WRAPV with Clang. Problem reported privately by Mattias Engdegård. Also, insulate intprops.h and verify.h better against each other’s definitions of __has_builtin on non-Clang hosts. * lib/intprops.h (__has_builtin): Define a temporary substitute if __has_builtin is not already defined. (_GL_HAS___builtin_add_overflow, _GL_TEMPDEF___has_builtin): New temporary internal macros. (_GL_HAS_BUILTIN_ADD_OVERFLOW, _GL_HAS_BUILTIN_MUL_OVERFLOW): Now two separate macros, replacing the old _GL_HAS_BUILTIN_OVERFLOW, since we no longer assume that __builtin_mul_overflow is like the rest. All uses changed. (INT_ADD_WRAPV, INT_SUBTRACT_WRAPV, INT_MULTIPLY_WRAPV): Adjust to above changes. (_GL_INT_OP_WRAPV): Remove ‘builtin’ arg, since it’s no longer relevant. All uses changed. * lib/verify.h (__has_builtin): Treat like intprops.h, so that the two .h files do not collide with each other. (_GL_HAS___builtin_unreachable, _GL_HAS___builtin_trap) (_GL_TEMPDEF___has_builtin): New temporary internal macros.
