--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Georg-Johann Lay <g...@gcc.gnu.org>: https://gcc.gnu.org/g:a9e313ed38775b3ffee650d5396419ce3e6ea389 commit r14-10186-ga9e313ed38775b3ffee650d5396419ce3e6ea389 Author: Georg-Johann Lay <a...@gjlay.de> Date: Wed May 8 17:56:05 2024 +0200 AVR: target/114981 - Support __builtin_powi[l] / __powidf2. This supports __powidf2 by means of a double wrapper for already existing f7_powi (renamed to __f7_powi by f7-renames.h). It tweaks the implementation so that it does not perform trivial multiplications with 1.0 any more, but instead uses a move. It also fixes the last statement of f7_powi, which was wrong. Notice that f7_powi was unused until now. PR target/114981 libgcc/config/avr/libf7/ * libf7-common.mk (F7_ASM_PARTS): Add D_powi * libf7-asm.sx (F7MOD_D_powi_, __powidf2): New module and function. * libf7.c (f7_powi): Fix last (wrong) statement. Tweak trivial multiplications with 1.0. gcc/testsuite/ * gcc.target/avr/pr114981-powil.c: New test. (cherry picked from commit de4eea7d7ea86e54843507c68d6672eca9d8c7bb)
