Instructions that set two pseudos aren't rematerialisation candidates in themselves, but we still need to track them if another instruction that sets the same register is a rematerialisation candidate. 2020-04-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR rtl-optimization/94605 * early-remat.c (early_remat::process_block): Handle insns that set multiple candidate registers. gcc/testsuite/ PR rtl-optimization/94605 * gcc.target/aarch64/sve/pr94605.c: New test.
