New Revision: 267122

URL: https://gcc.gnu.org/viewcvs?rev=267122&root=gcc&view=rev
Log:
match_asm_constraints: Use copy_rtx where needed (PR88001)

The new insn here (temporarily) illegally shares RTL.  This fixes it.


        PR rtl-optimization/88001
        * function.c (match_asm_constraints_1): Don't invalidly share RTL.
