Makarov <vmaka...@redhat.com> Date: Thu Feb 18 17:49:26 2021 -0500 [PR96264] LRA: Check output insn hard regs when updating available rematerialization after the insn Insn for rematerialization can contain a clobbered hard register. We can not move such insn through another insn setting up the same hard register.
