[PATCH v10 0/7] MR7111: Draft: support building Wine with LTO
work is still in progress. todo: - ensure that all affected sources (i.e. C sources with any kind of assembly) are listed in either way for all architectures - test Wine built with LTO relevant bug reports: - https://bugs.winehq.org/show_bug.cgi?id=41712 - https://bugs.winehq.org/show_bug.cgi?id=51051 -- v10: LTO quirks configure: enable building Wine with LTO makedep: support skipping/disabling LTO makedep: support LTO builds winegcc: support LTO builds winebuild: support LTO builds tools: helper functions for LTO builds https://gitlab.winehq.org/wine/wine/-/merge_requests/7111
