Hello,
attached typecode.ii preprocessed file shows 40% regression in compile-time
while compiled with 3.5.0 in comparison with 3.4.1 when -O1 optimization is
used. To be correct, 40% regression is shown on not-preprocessed file. When I
compile file preprocessed by 3.5.0 with 3.4.1, the regression is only about 30%
which seems like 3.5.0's libstdc++ library is either bigger or slower to
compiler with.
Cheers,
Karel
