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
-- v9: 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
