[Bug 223415] lang/rust: don't require SSE2 on i386 (at least for binary packages)

Building locally isn't recommended: textproc/ripgrep as -j1 has MaxRSS ~539 MiB. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"

It seems xmm registers are used by __floatdidf and __floatundidf from compiler-rt. Rust compiler always includes optimized routines on i386 but not always uses them. If my understanding is correct then the code is dead. # Rust 1.22.1 https://github.com/rust-lang-nursery/compiler-builtins/blob/0b9844764ea1/build.rs#L3977 https://github.com/rust-lang-nursery/compiler-builtins/blob/0b9844764ea1/src/float/conv.rs#L91 https://github.com/rust-lang-nursery/compiler-builtins/blob/0b9844764ea1/src/float/conv.rs#L120 https://github.com/rust-lang/compiler-rt/blob/c8a8767c56ad/lib/builtins/i386/floatdidf.S https://github.com/rust-lang/compiler-rt/blob/c8a8767c56ad/lib/builtins/i386/floatundidf.S -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223415 --- Comment #14 from Bertrand Petit --- (In reply to Jan Beich from comment #13) You are likely correct. However you have just uncovered a different bug, a replication on one already fixed in src: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221733 You may want to adress it to rid the rust bootstrap of SIMD instructions. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
