I have a question about the partial pre (-ftree-partial-pre) optimization
that was added in GCC 4.8. I have noticed that this optimization is slowing
down the bitmnp01 benchmark in the EEMBC1.1 suite on MIPS. I see this with
the 4.8 GCC and with ToT GCC.
I have a question about the partial pre (-ftree-partial-pre) optimization
that was added in GCC 4.8. I have noticed that this optimization is slowing
down the bitmnp01 benchmark in the EEMBC1.1 suite on MIPS. I see this with
the 4.8 GCC and with ToT GCC. Comparing "-O3 -fno-tree-partial-pre" vs.
