>Release: GNU C version 3.2 20020615 (experimental) (vax-netbsdelf)
>Organization:
>Environment:
cross-compiler on NetBSD-1.6A i386
>Description:
After updating GCC via anoncvs, the included file fails to compile at any optimization level. Though GNU C version 3.2 20020610 (experimental) (vax-netbsdelf) from 5 days ago compiled it fine.
>How-To-Repeat:
Compile this:
void
xx(int a)
{
switch (a) {
case 1: z(); break;
case 5: x(); break;
case 7: v(); break;
case 11: s(); break;
case 13: q(); break;
}
}
results in:
./cc1 -version -O0 -quiet /tmp/x.i
GNU C version 3.2 20020615 (experimental) (vax-netbsdelf)
compiled by GNU C version 2.95.3 20010315 (release) (NetBSD nb2).
/tmp/x.i: In function `xx':
/tmp/x.i:18: error: missing barrier after block 0
/tmp/x.i:18: internal compiler error: verify_flow_info failed
