Makarov <vmakarov@redhat.com> Date: Tue Mar 19 16:57:11 2024 -0400 [PR99829][LRA]: Fixing LRA ICE on arm LRA removed insn setting equivalence to memory whose output was reloaded. This resulted in writing an uninitiated value to the memory which triggered assert in LRA code checking the final generated code. This patch fixes the problem. Comment in the patch contains more details about the problem and its solution. gcc/ChangeLog: PR target/99829 * lra-constraints.cc (lra_constraints): Prevent removing insn with reverse equivalence to memory if the memory was reloaded.
