According to this bug those options needed to be added for polly to work with Arch's clang.
EDIT:
Upon further reflection the better change is to add the necessary flags to the polly line and add check_buildoption "polly" "y" && to the beginning of the line.
In addition, the -freg-struct-return needs to be moved into the line check_buildoption "rice" "y" && because clang does not support it on x86_64 so should not be used I think with rice-clang.
@tjuh upx is more or less useless because most binaries are application/x-pie-executable and application/x-sharedlib, and this will fail with a NotCompressibleException or a CantPackException
Alright, thanks for clarifying. So does that mean that using upx to compress pkgs with makepkg is useless, since it will pretty much always fail?
@Tjuh
@brikler is correct, upx itself does not discriminate, but some kinds of executables will fail to run if compressed.
To be honest, documentation on this topic is lacking. There are a few links in these comments, as well as instructions for how to add new filetypes.
If you find any new filetype that works (compressed executables run), let me know.
Same if you find a problem with my script. I have been over this particular part of it countless times. Upstream discarded this, maybe they had reasons (never found any discussion of it).
@Tjuh makepkg-optimze tests the file before compress but upx doesn't test and you can compress every compressible file. you can test the file type with: file --brief --mime-type <fileToTest>
Are you sure about that? I tried a couple of times to manually compress files which makepkg gave a warning about not being able to compress and they compressed just fine with upx --ultra-brute filename.
@Tjuh what do you mean? not compressed binaries? makepkg-optimize only compress binaries from the type application/x-executable but not application/x-sharedlib and the most binaries are from the type x-sharedlib
Have not been able to properly use upx in months and think because of this pkg, can anyone confirm please?
oxipng claims to be significantly faster than optipng. Could you consider adding it as an optional dependency?
@brikler
See commentary on the additional buildenv options; because clang and gcc are inexplicably not using equivalent flags for equivalent functions, and there is no mechanism for makepkg to detect which toolchain is to be used, I have been forced to make a completely different set of options for clang.
You want lto-thin-clang and poly.

makepkg-optimize is a collection of libmakepkg tidy, buildenv, and executable extensions, and a supplement to pacman. These enable various optimization routines for building and packaging such as upx compression, profile guided optimization, polyhedral model optimization, etc..
Note: Over-optimization is a thing, and it is not good.
See the wiki article for details.
Note to packagers: makepkg-optmize's macros may be enabled or disabled in options() as well!
