cfallin opened PR #10748 from cfallin:backport-10747-to-33.0.0 to bytecodealliance:release-33.0.0:
Prior versions of regalloc2 could not support more than 255 operands on an instruction, and together with the integrated return-value loads on call instructions introduced in #10502, this caused issues with calls with many returns. This PR upgrades to a version of RA2 that supports up to
2^16 - 1operands per instruction (well in excess of the maximum of 1000 return/result values per Wasm's implementation limits, for example).
