Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

C source code
The attached C code, when compiled by flags -c -w -O3 -march=native,
does this:
destDir/testFile.5246.c: In function ‘func_12’:
destDir/testFile.5246.c:1626:1: internal compiler error: in trunc_int_for_mode,
at explow.c:59
0x5baff7 trunc_int_for_mode(long, machine_mode)
../../trunk/gcc/explow.c:59
0x103a468 trunc_int_for_mode(poly_int<1u, long>, machine_mode)
../../trunk/gcc/explow.c:87

../../trunk/gcc/emit-rtl.c:532
0x1fcc72b neg_const_int
../../trunk/gcc/simplify-rtx.c:69
/proc/cpuinfo says
model name : AMD FX(tm)-8350 Eight-Core Processor
I'll have my usual go at reducing the code and finding a range
of revisions where it went wrong.
