Compiles with ruts-1.51
(In reply to Oleg from comment #3) > Compiles with ruts-1.51 I use rust-bin because compiling it with a PinePhone would probably kill it forever
ping: News about that bug?
I cannot help you. Not reproducible for amd64 or x86. packed_simd upstream (Mozilla) hasn't been touched since bug 756334. Try to build just https://github.com/hsivonen/packed_simd/archive/0917fe780032a6bbb23d71be545f9c1834128d75.tar.gz which should fail (=that's the version spidermonkey uses). Now try to build latest https://github.com/rust-lang/packed_simd to see if a newer version works for you.

Seems the problem is only on arm/64 arches. I will try with PinePhone tomorrow and report back
I can try to reproduce on my arm64, but I need emerge -pv spidermonkey from you, and possibly emerge --info spidermonkey which is your active version of gcc?

this happens because rustc_args_required_const was removed in rust-1.54, upstream pullrequst is here: https://github.com/rust-lang/rust/pull/85110 mozilla bug with request to update rust_simd package: https://bugzilla.mozilla.org/show_bug.cgi?id=1719674 firefox + firefox-esr also affected
backported patch for firefox-esr and spidermonkey:78 https://bugzilla.mozilla.org/show_bug.cgi?id=1719674#c11 seems its not going to be backported, so maybe the mozilla team wants to add this to the patchset when rust-1.54.0 is released and added to the tree. same for not yet released firefox-90.0: https://bugzilla.mozilla.org/show_bug.cgi?id=1719674#c13

@mozilla team: the fix was *not* backported to new esr-91 branch, if you're not happy about it please comment on the upstream bug to maybe convince them.
