I benchmarked code generated by gcc and it is 10% faster on integer
and 25% on floating operations than egcs and this whatever target (ie
-m486, -mpentium, -mpentiumpro) you could choose. In addition
I suspect you can choose a higher -O number (ie -O3 versus -O2) with
gcc-2.95 without generating wrong code. The performance gap will only
increase with time as egcs development is now stopped.
In addition I have compiled C++ packages using its libstdc++ library
and linked against auxiliary libraries (eg qt) who were vanilla redhat
(built with egcs against the old library) and it seems to work.
I certainly would like to see gcc-2.95 or higher in next redhat. This
would also destroy one of Mandrake's assets over RedHat.
By the way does anyone know if it safe to use -mpentium and
-mpentiumpro with gcc-2.95? And is it safe to use in compiling the
kernel,
