Hi,
Gently ping the series of patches.
[PATCH-1, rs6000]Add a new type of CC mode - CCBCD for bcd insns [PR100736,

[PATCH-2, rs6000] Add a new type of CC mode - CCLTEQ
Hi,
It's the first patch of a series of patches optimizing CC modes on
rs6000.
bcd insns set all four bits of a CR field. But it has different single
bit reverse behavior than CCFP's. The forth bit of bcd cr fields is used
to indict overflow or invalid number. It's not a bit for unordered
