--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Georg-Johann Lay <[email protected]>: https://gcc.gnu.org/g:29e4b7f1100ad3dd611da6fc3314a41978c5fc25 commit r17-759-g29e4b7f1100ad3dd611da6fc3314a41978c5fc25 Author: Georg-Johann Lay <[email protected]> Date: Sun May 24 22:16:46 2026 +0200 AVR: target/125409 - Add fixed-point conversions to / from [u]int24_t. The test cases ran into ld: undefined reference to `__fractunssapsi' ld: undefined reference to `__fractunspsisa' etc. because the backend didn't implement these conversions. The worker function that outputs fixed-point conversions inline, avr_out_fract, is generic enough to handle 24-bit integral modes, so adding PSImode to the mode iterators in avr-fixed.md fixes the issue.
