------- Comment #3 from pinskia at gcc dot gnu dot org 2007-12-26 14:21 -------
Confirmed, reduced testcase:
struct DState{
unsigned char mtfa [4096];
int mtfbase[256 / 16];
} ;
int makeMaps_d ( struct DState* s, int kk )
{
int ii, jj;
for (ii = 256 / 16 - 1; ii >= 0; ii--) {
for (jj = 16 -1; jj >= 0; jj--) {
s->mtfa[kk] = 16;
kk--;
}
s->mtfbase[ii] = kk + 1;
}
}
