![]() builtin macros This patch implements the __is_target_arch, __is_target_vendor, __is_target_os, and __is_target_environment Clang preprocessor extensions that were proposed by @compnerd in Bob's cfe-dev post: http://lists.llvm.org/pipermail/cfe-dev/2017-November/056166.html. These macros can be used to examine the components of the target triple at compile time. A has_builtin(is_target_???) preprocessor check can be used to check for their availability. __is_target_arch allows you to check if an arch is specified without worring about a specific subarch, e.g. __is_target_arch(arm) returns 1 for the target arch "armv7" __is_target_arch(armv7) returns 1 for the target arch "armv7" __is_target_arch(armv6) returns 0 for the target arch "armv7" __is_target_vendor and __is_target_environment match the specific vendor or environment. __is_target_os matches the specific OS, but __is_target_os(darwin) will match any Darwin-based OS. "Unknown" can be used to test if the triple's component is specified. rdar://35753116 Differential Revision: https://reviews.llvm.org/D41087 llvm-svn: 320734 |
