The feature gate for the issue is #![feature(asm_experimental_arch)].

Summary

This feature tracks asm! and global_asm! support for the following architectures:

  • NVPTX
  • PowerPC
  • Hexagon
  • MIPS32r2 and MIPS64r2
  • wasm32
  • BPF
  • SPIR-V
  • AVR
  • MSP430

Status

Each architecture needs to be reviewed before stabilization:

  • It must have clobber_abi.
  • It must be possible to clobber every register that is normally clobbered by a function call.
  • Generally review that the exposed register classes make sense.

Is there any chance that wasm32 assembly support will be stabilized any time soon? Are there any tasks where contributions might speed this up?

Enable feature(asm_experimental_arch) for tests
6a74e1f 
This is needed to use `probe!` on ppc64le and s390x

See rust-lang/rust#93335

Also loosen version requirement on `probe`; on Fedora we have been
building with `probe` 0.5.1 with no issue.

Tested by doing a scratch build on Fedora's Koji build system:

Gate out test functions that use probe! on ppc64le and s390x

These require `feature(asm_experimental_arch)` which only works on
nightly compilers.
