Current internal option -static-func-full-module-prefix keeps all the directory path the profile counter names for static functions. The default of this option is false. This strips the directory names from the source filename which is problematic: (1) it creates linker errors for profile-generation compilation, exposed in our internal benchmarks. We are seeing messages like "warning: relocation refers to discarded section". This is due to the name conflicts after the stripping. (2) the stripping only applies to getPGOFuncName. Current Thin-LTO module importing for the indirect-calls assumes the source directory name not being stripped. Current default value for this option can potentially prevent some inter-module indirect-call-promotions. This patch turns the default value for -static-func-full-module-prefix to true. The second part of the patch is to have an alternative implementation under the internal option -static-func-strip-dirname-prefix=<value> This options specifies level of directories to be stripped from the source filename. Using a large value as the parameter has the same effect as -static-func-full-module-prefix. Differential Revision: http://reviews.llvm.org/D29512 llvm-svn: 296206 |
