Cannot reproduce locally, the std test suite completes successfully.

Just double checking, you removed the if here and tried it?

zig/std/fmt/parse_float.zig

Lines 385 to 388 in dc3c419

Another issue, I suspect we have a problem with compiler-rt when hard-float enabled:

I'm disabling a lot of the math tests for armv8-linux-musleabihf.

[SamTebbs33]

The parseFloat failure is fixed and the math and filesize tests are still failing. Command used: zig test lib/std/std.zig -target armv8_5a-linux-musleabihf --test-cmd qemu-arm --test-cmd-bin --override-lib-dir lib
