This ICE is caused because of this situation:
mask__49.21_99 = vect__17.19_96 == { 0.0, ... };
...
vect__6.24_107 = .MASK_LEN_LOAD (vectp.22_105, 32B, mask__49.21_99,
POLY_INT_CST [2, 2], 0);
The MASK_LEN_LOAD is using real MASK which is produced by the EQ comparison
wheras the LEN
is the dummy LEN which is the vectorization factor.
In this situation, we didn't enter 'vect_record_loop_len' since there is no LEN
loop control.
Then 'LOOP_VINFO_RGROUP_IV_TYPE' is not suitable type for 'build_int_cst' used
for producing
LEN argument for 'MASK_LEN_LOAD', so use sizetype instead which is perfectly
matching
RVV length requirement.
PR middle-end/110989
gcc/ChangeLog:
* tree-vect-stmts.cc (vectorizable_store): Replace iv_type with
sizetype.
(vectorizable_load): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/pr110989.c: New test.
