I have the following error when compiling a file from linux kernel (attached).
Command line:
m68k-elf-gcc -w -O1 -c pr.c
Output:
pr.c: In function 'nfs_statfs':
pr.c:8757: error: unrecognizable insn:

Confirmed, reduced testcase:
struct statfs {
int f_bsize;
};
struct super_block {
unsigned long s_blocksize;
};
struct nfs_fsinfo {
unsigned long long bsize;
};
int statfs (struct nfs_fsinfo *);
int nfs_statfs(struct super_block *sb, struct statfs *buf)
{
unsigned char blockbits;
struct nfs_fsinfo res;
statfs(&res);
if (res.bsize == 0)
res.bsize = sb->s_blocksize;
buf->f_bsize = nfs_block_bits(res.bsize);
}

m68k is not a primary or secondary platform; removing target milestone.
