Running GHC in parallel with --make would be nice, but I find on Windows that the link time is the bottleneck for most projects.
Yes, when GHC calls GNU ld, it can be very costly. In my experience, on a
This is also my experience. GNU ld is old and slow. I believe its generality also hurts it, there is a much faster linker called gold, but it's ELF-only.
For someone like me, who only is interested in ELF on Linux, is there some way of getting GHC to use gold instead of ld?
In conclusion, improving GNU ld could be a huge win for GHC, at least on linux. Does GHC on windows use GNU ld?
Improving GNU ld would be a huge win in a lot of places, and the fact that no one has done it (excepting gold of course) goes to show it's a lot easier said than done!
It could also mean that ld is good enough. Similar to how CVS was good enough for an awfully long time... ;-) /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe
