GO COMPRESSES RISCV RETURNS, SHAVES 2,700 INSTRUCTIONS

By RepoJournal · Filed 06:56 UTC on August 9, 2026 · About Go

Joel Sing @4a6f656c 1 cited

The Go compiler just cut another 2,700 instructions from binaries on linux/riscv64 by compressing bare function returns.

Joel Sing landed an optimization [1] that replaces JALR instructions used for bare returns with the compressed CJR variant, a safe compression since relocations never attach to bare returns. This is the kind of surgical binary size win that compounds across large deployments. Separately, Robert Griesemer fixed a spec typo [2] that was blocking issue 80784. Both landed in the last 24 hours across 2 commits on the main Go repo.
