Greetings,
tbench 8 throughput on my i4790 box:
1 2 3 avg
master 3769.95 3759.28 3762.83 3764.02 1.000
master-framepointer 3476.73 3453.52 3460.62 3463.62 .920
Does anyone know why the performance impact is this large?
The only thing I found googling was a reference to 3 arg lea using rbp
or r13 being slow, which wasn't particularly helpful. Nor was staring
at asm deltas with non-expert eyeballs.
