Bug ID: 107435
Summary: ice in build_vector_from_val, at tree.cc:2125
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 53780
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53780&action=edit
C source code
For the attached code, compiled with
-std=gnu89 -O3 -march=znver3 -c bug858.c
recent gcc does this:
during GIMPLE pass: vect
src/io/trove/trove-dbpf/dbpf-open-cache.c: In function
‘dbpf_open_cache_initiali
ze’:
src/io/trove/trove-dbpf/dbpf-open-cache.c:100:6: internal compiler error: in
bui
ld_vector_from_val, at tree.cc:2125
0x1072d8e build_vector_from_val(tree_node*, tree_node*)
../../trunk.git/gcc/tree.cc:2124
0x100a927 vectorizable_recurr(_loop_vec_info*, _stmt_vec_info*, gimple**,
_slp_t
ree*, vec<stmt_info_for_cost, va_heap, vl_ptr>*)
../../trunk.git/gcc/tree-vect-loop.cc:8472
The bug first seems to occur sometime between git hash baeec7cc83b19b46
and 3bd5d9a28e1ce4d1, a day later.
I have a reduction running.

--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:
struct qlist_head {
struct qlist_head *next
} qlist_add(struct qlist_head *new, struct qlist_head *head) {
struct qlist_head *prev = head;
new->next = head->next;
prev->next = new;
}
struct {
struct qlist_head queue_link
} free_list, prealloc[];
dbpf_open_cache_initialize() {
int i = 0;
for (; i < 64; i++)
qlist_add(&prealloc[i], &free_list);
}

Mine. Missing a conversion of the scalar pointer to the vector component type.
