When we're building a precompiled header or module against an SDK on Darwin, there will be a file SDKSettings.plist in the sysroot. Since stat()'ing every system header on which a module or PCH file depends is performance suicide, we instead stat() just SDKSettings.plist. This hack works well on Darwin; it's unclear how we want to handle this on other platforms. If there is a canonical file, we should use it; if not, we either have to take the performance hit of stat()'ing system headers repeatedly or roll the dice by not checking anything. llvm-svn: 177194 |
