--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jeff Law <[email protected]>: https://gcc.gnu.org/g:2f84ad4ddc2a2dc93584d87da347c444a77f429c commit r16-7404-g2f84ad4ddc2a2dc93584d87da347c444a77f429c Author: Jeff Law <[email protected]> Date: Sun Feb 8 08:23:07 2026 -0700 [PR target/123911][RISC-V] Fix infinite recursion in riscv_legitimize_move I kept hoping I'd see a better solution, perhaps one where chunks of this routine just go away, but that hasn't materialized. So... This patch avoids infinite recursion through riscv_legitimize_move. Essentially we end up calling it recursively with arguments that are a nop-move and those particular arguments trigger infinite recursion. So this patch just recognizes and elides the nop move. Bootstrapped on riscv64-linux-gnu and regression tested on riscv{32,64}-elf with no regressions. Pushing to the trunk.
