Hi all,
I've been experimenting with sorting recently and I have noticed a
possibility to slightly optimize the sorting of std::pair values using
the default < operator. This is, I believe, a common usage case to
retrieve sorting indices (better locality of reference than sorting
via pointers). At

I have a single issue pipeline that I need to schedule more accurately. For
the most part this is fine but the CPU is a 32-bit design but for 64-bit
opcodes (DImode or DFmode) I need to generate 2 opcodes and not one, but these
only appear as a single instruction until after reload has run. Wh

but mysteriouslty the declarations are missing. What am I missing? Is there
