Hello,
The following is a summary of discussion I had with Ayal regarding the patch:
Some background: currently, SMS supports only targets where the doloop
pattern is decoupled from the rest of the loop's instructions (for example
PowerPC) (we'll call it 'case decoupled' for simplicity) In this
My apologies, the previous email refers to the patch:
http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00350.html
- Support closing_branch_deps
and not to 'Avoid considerin​g debug_insn when calculatin​g SCCs' as
the title implies.
Thanks,
Revital
Hello,
The attached patch avoids considering debug_insn when calculating SCCs.
With this change the existence of debug_insn does not influence
the scheduling order and rec_MII.
Bootstrap and regtest on ppc64-redhat-linux and regtest on arm-linux-gnueabi.
OK for mainline?
Thanks,
Revital
