Makarov <vmaka...@redhat.com> Date: Wed Feb 24 13:54:10 2021 -0500 [PR99123] inline-asm: Don't use decompose_mem_address to find used hard regs Inline asm in question has empty constraint which means anything including memory with invalid address. To check used hard regs we used decompose_mem_address which assumes memory with valid address. The patch implements the same semantics without assuming valid addresses. gcc/ChangeLog: PR inline-asm/99123 * lra-constraints.c (uses_hard_regs_p): Don't use decompose_mem_address. gcc/testsuite/ChangeLog: PR inline-asm/99123 * gcc.target/i386/pr99123.c: New.
