alexcrichton opened PR #7250 from alexcrichton:rv64-spectre-improvements to bytecodealliance:main:

This commit optimizes some select_spectre_guard patterns which are frequently generated with the wasm backend when dynamic bounds checks are enabled by pattern-matching when one of the values being selected is zero. This enables shaving off a few instructions which can be constant folded away.
