Rick Altherr 3c48de8e21 rtlil: Improve performance of SigSpec::extract(SigSpec, SigSpec*) 
Converting to a pool<SigBit> is fairly expensive due to inserts somewhat
frequently causing rehashing.  Instead, walk through the pattern SigSpec
directly on a chunk-by-chunk basis and apply it to this SigSpec's
individual bits.  Using chunks for the pattern minimizes the number of
iterations in the outer loop.

Rick Altherr 0265d7b100 rtlil: speed up SigSpec::sort_and_unify() 
std::set<> internally is often a red-black tree which is fairly
expensive to create but fast to lookup.  In the case of
sort_and_unify(), a set<> is constructed as a temporary object to
attempt to speed up lookups.  Being a temporarily, however, the cost of
creation far outweights the lookup improvement and is a net performance
loss.  Instead, sort the vector<> that already exists and then apply
std::unique().

Trivial changes to fix Mac OS build
 2015-12-15 19:54:07 +01:00
Micah Elizabeth Scott 7948156abf Mac build fix, gsed -> sed 
Homebrew is calling its GNU sed just 'sed' now.

Micah Elizabeth Scott 93f6f68b65 Remove nonportable "-r" option from xargs 
On Linux, this avoids an empty "rm -f" call when there's nothing to clean. But it isn't portable, and it causes the build to fail on Mac OS. It doesn't seem to be harmful to remove this option entirely, and it's a step toward fixing the Mac build.
