1.74 fails to build on mips with LTO: relocation truncated to fit: R_MIPS_TLS_GOTTPREL against `std::collections::hash::map::RandomState::new::KEYS::__getit::__KEY'

[matoro]

Hi, 1.74 (tried 1.74.1) fails to build on mips when upgrading from 1.73.0. 1.73.0 rebuilds itself just fine. My platform is big-endian mips64.

error: linking with `mips64-unknown-linux-gnu-gcc` failed: exit status: 1

FYI, rustc's support for this target was recently demoted to tier 3.

Turns out this happens only with LTO enabled, it does not occur without. (LTO via in config.toml):

[rust]
lto = fat

I'm trying to reproduce the issue but to no avail. Are you still getting the same issue? Can you provide more information?
I am trying to reproduce it for mips64-unknown-linux-gnuabi64.

Hey, thanks for checking this out. I just tested 1.75.0 and the issue does not occur there. Appreciate it!
