--- Comment #21 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Georg-Johann Lay <g...@gcc.gnu.org>: https://gcc.gnu.org/g:e128cfd819a492e5989b9277bb4a70380e1915b1 commit r13-9880-ge128cfd819a492e5989b9277bb4a70380e1915b1 Author: Georg-Johann Lay <a...@gjlay.de> Date: Sat Sep 6 13:38:48 2025 +0200 AVR: Disable tree-switch-conversion per default. There are at least two cases where tree-switch-conversion leads to unpleasant resource allocation: PR49857 The lookup table lives in RAM. This is the case for all devices that locate .rodata in RAM, which is for almost all AVR devices. PR81540 Code is bloated for 64-bit inputs. As far as PR49857 is concerned, a target hook that may add an address-space qualifier to the lookup table is the obvious solution, though a respective patch has always been rejected by global maintainers for non-technical reasons. gcc/ PR target/81540 PR target/49857 * common/config/avr/avr-common.cc: Disable -ftree-switch-conversion. (cherry picked from commit 912159d2b5429c3126756b56723dd4f32dd56bdd)
