This is because function_instance::reads_global_state_p() does not take CP_READ_MEMORY into account. Fixing this gives vld1 the "pure" attribute instead, and solves the problem. 2024-03-15 Christophe Lyon <christophe.l...@linaro.org> PR target/114323 gcc/ * config/arm/arm-mve-builtins.cc (function_instance::reads_global_state_p): Take CP_READ_MEMORY into account. gcc/testsuite/ * gcc.target/arm/mve/pr114323.c: New.
