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
-- v6: 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

Thanks. I'm still not a fan of the environment variables like `WINE_AR`, is there a reason you aren't just unconditionally using `gcc-ar` if available? It is a superset of `ar` anyway. I think you should split the last patch, yeah. In particular, you disable too many files. For example, why are you disabling `d3d9/device.c` from having LTO? A lot of those files can also be "fixed" by fixing just the actual cause of the issue (for example, marking functions with `used` attribute) instead of disabling LTO completely. The only problematic ones are those **exporting** asm functions. I think it would be great for Wine to have LTO. But well, it's not really up to me. Alexandre hasn't really commented on any of the LTO MRs. :/
I don't want to hardcode toolchain-based tool names because Wine is buildable with Clang or GCC and if both are present in environment this may lead to unforeseen consequences. Both winebuild and winegcc have similar tool/binary lookup functions so I'd write unified implementation.
Last patch is merely quirk so it may disable LTO for more sources than is actually required.

I don't want to hardcode toolchain-based tool names because Wine is buildable with Clang or GCC and if both are present in environment this may lead to unforeseen consequences. Both winebuild and winegcc have similar tool/binary lookup functions so I'd write unified implementation. Last patch is merely quirk so it may disable LTO for more sources than is actually required.
I'm pretty sure it already uses heuristics and such to detect build system in use, so "hardcoding" is fine as long as it has fallbacks.
Having an option like --enable-lto and requiring env vars for it to work is not good design IMO.

This is second variant of common LTO functions (they were in `tools/tools.h` before). If I remove "used" attribute from function definition then compiler emits warning (`-Wunused-function`) and with `-Werror` it produces build error - that's because not all of them are used in affected tools. Both variants - "used" attribute or "inline" - are looking not so good as it should be but I've chosen first one. However I'll apply your suggestions if there're any.
If you want it to act like a "macro" in a header just use `static inline`, it's used all over the place in wine.
