--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Surya Kumari Jangala <jskum...@gcc.gnu.org>: https://gcc.gnu.org/g:02ecc9a26324d142c5cd19d24526b9c23aabc1c3 commit r14-3251-g02ecc9a26324d142c5cd19d24526b9c23aabc1c3 Author: Surya Kumari Jangala <jskum...@linux.ibm.com> Date: Mon Aug 14 09:34:56 2023 -0500 ira: update allocated_hardreg_p[] in improve_allocation() [PR110254] The improve_allocation() routine does not update the allocated_hardreg_p[] array after an allocno is assigned a register. If the register chosen in improve_allocation() is one that already has been assigned to a conflicting allocno, then allocated_hardreg_p[] already has the corresponding bit set to TRUE, so nothing needs to be done. But improve_allocation() can also choose a register that has not been assigned to a conflicting allocno, and also has not been assigned to any other allocno. In this case, allocated_hardreg_p[] has to be updated. 2023-07-21 Surya Kumari Jangala <jskum...@linux.ibm.com> gcc/ PR rtl-optimization/110254 * ira-color.cc (improve_allocation): Update array allocated_hard_reg_p.
