- Subject: [PATCH, pretty-ipa merge 0/4] IPA-SRA
Hi,
this patch-set is a proposed merge of IPA-SRA from the pretty-ipa
branch to the trunk. I have talked about IPA-SRA at the summit and it
is also described in the paper. Shortly, it changes the parameters of
local functions in the following ways:
- removes parameters that are not used at all,
- passes parameters by value instead of by reference if possible and
hopefully profitable
- passes only parts of aggregate parameters if only those are used
in the function (often combined with the above transformation)
The pass has been sitting in pretty-ipa for some time, I have
bootstrapped it on i386-linux and x86_64-linux where I also ran the
regression testsuite without any new problems popping up.
I'd like therefore ask for the final review and hopefully an ACK to
commit to trunk.
Thanks,
Martin
