Hi,
Attached is a patch to fix count_leading_zeros for mc68020.
count_leading_zeros fails to assemble because '{' and '}' in the
assembly are understood as the special characters for assembly
dialect.
The patch fixes the problem by replacing '{' and '}' with '%{' and
'%}', respectively.
I didn't catch this in my previous patch because I was building gcc
with --with-arch=cf.
Tested by building m68k-elf. Committed as obvious.
