I see the same issue w/ the following snippet compiled w/ -O2
-ftree-parallelize-loops=2 -floop-nest-optimize -g:
int te[9];
void
dt (int cz)
{
while (cz < 1)
{
int xy;
for (xy = 0; xy < 9; ++xy)
te[xy] = 0;
++cz;
}
}
% gcc-8.0.0-alpha20180211 -O2 -ftree-parallelize-loops=2 -floop-nest-optimize
-g -c pr84404.c
/tmp/ccfu80w2.s: Assembler messages:
/tmp/ccfu80w2.s:700: Error: leb128 operand is an undefined symbol: .LVU12
as of r257571.
GNU as 2.30 seems to be the key here.
