Hi,
This patch fixes an insertion point for instructions generated by
validize_mem in dimode_scalar_chain::convert_op. Patch also fixes
scanned instruction pattern to fix test for Darwin.
I bootstrapped and regtested it on x86_64-pc-linus gnu.
Dominique d'Humieres tested it for Darwin. OK for trunk?
Thanks,
Ilya
