Hi,
In the process of setting up a new development environment, I
noticed that DMD's codegen seems to outperform GDC's or LDC's
when building DMD itself.
I wrote a test script to measure the time it takes for DMD
(built with different compilers) to build Phobos:
http://dump.thecybershadow.net/9e42ff2858d1419cf41108cc50b0a83a/bench.sh
My results are:
dmd: 11.26
ldc: 15.35
gdc: 14.80

How memory is allocated makes a huge difference.
Thanks :) After changing that to version(all), LDC is faster now.
Doesn't build with GDC though (multiple definitions)...
