Hi,

Since r11-1621-gd32708e796504eaeaad7d19990909204d74f9ba3
I have noticed:
FAIL: gcc.target/aarch64/sve/mask_load_slp_1.c -march=armv8.2-a+sve (internal
compiler error)
FAIL: gcc.target/aarch64/sve/mask_load_slp_1.c -march=armv8.2-a+sve (test for
excess errors)
Excess errors:
/gcc/testsuite/gcc.target/aarch64/sve/mask_load_slp_1.c:8:1: error: definition
in block 3 follows the use
for SSA_NAME: mask_patt_58.126_186 in statement:
vec_mask_and_190 = mask_patt_58.126_186 & loop_mask_189;
during GIMPLE pass: vect
/gcc/testsuite/gcc.target/aarch64/sve/mask_load_slp_1.c:8:1: internal compiler
