Summary: [12 Regression] ICE in DECL_FUNCTION_CODE, at
tree.h:4006
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org

gcc-12.0.0-alpha20210801 snapshot (g:6f0c43e97825ee54e3779afbedcd0def12443001)
ICEs when compiling the following testcase, reduced from
gcc/testsuite/gcc.target/aarch64/abs_2.c, w/ -fanalyzer:
void
foo (int vget_lane_u64___a)
{
__builtin_aarch64_im_lane_boundsi (sizeof (vget_lane_u64___a),
sizeof (vget_lane_u64___a), 0);
}
% aarch64-linux-gnu-gcc-12.0.0 -fanalyzer -c k1ngarza.c
during IPA pass: analyzer
k1ngarza.c: In function 'foo':
