Bug ID: 111092
Summary: ice expand_fn_using_insn, at internal-fn.cc:214
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C code:
typedef struct {
long r;
long c
} bool_mat_struct;
bool_mat_struct bool_mat_randtest_diagonal_mat;
bool_mat_randtest_diagonal_n;
bool_mat_randtest_diagonal() {
bool_mat_randtest_diagonal_n =
bool_mat_randtest_diagonal_mat.r > bool_mat_randtest_diagonal_mat.c
? bool_mat_randtest_diagonal_mat.c
: bool_mat_randtest_diagonal_mat.r;
}
compiled by recent gcc and compiler flags -O3 -march=znver2, does this:
