Bug ID: 83034
Summary: ice in mem_loc_descriptor, at dwarf2out.c :15669
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com

For the following C code:
float *a;
b;
__attribute__((__simd__)) float expf(float);
c() {
for (; b; b++) {
float c = expf(b);
a[b] = c;
}
}
recent gcc trunk and flags -funroll-loops -ffast-math -O3 -g does this:
(vec_series:V4SI (reg:SI 6 bp [orig:95 tmp.13 ] [95])
(const_int 1 [0x1]))during RTL pass: final
