--- Comment #18 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Vladimir Makarov <vmaka...@gcc.gnu.org>: https://gcc.gnu.org/g:2639f9d2313664e6b4ed2f8131fefa60aeeb0518 commit r13-6424-g2639f9d2313664e6b4ed2f8131fefa60aeeb0518 Author: Vladimir N. Makarov <vmaka...@redhat.com> Date: Thu Mar 2 16:29:05 2023 -0500 IRA: Use minimal cost for hard register movement This is the 2nd attempt to fix PR90706. IRA calculates wrong AVR costs for moving general hard regs of SFmode. This was the reason for spilling a pseudo in the PR. In this patch we use smaller move cost of hard reg in its natural and operand modes. PR rtl-optimization/90706 gcc/ChangeLog: * ira-costs.cc: Include print-rtl.h. (record_reg_classes, scan_one_insn): Add code to print debug info. (record_operand_costs): Find and use smaller cost for hard reg move. gcc/testsuite/ChangeLog: * gcc.target/avr/pr90706.c: New.
