Hi Bernd,
Experiments show that the
existing multi-if-block support isn't terribly effective on FRV;
before-after comparisons show that by turning it off, there are three
spots in gcc that are meaningfully changed, and below 20 in the C
benchmarks of SPEC2k.
FRV also doesn't build in mainline, and it looks as if it likely hasn't
in a while, so I haven't tried testing this patch on it. If no public
manual can be found, is it still my responsibility to keep this support
working, or can we put the burden on the FRV maintainers?
You can put in on the FRV maintainers. Although now that the FRV port
does build it would be very much appreciated if you could provide a
patch for this backend as well.
Cheers
Nick
