Re: Adding a "release" setting in build.mk.sample (and some other build system questions)

The default (and thus release) `SRC_HC_OPTS` uses `-H32m` (see mk/ config.mk.in). Maybe you want to run some tests to see if it makes a difference on the total build time? I suggest also measuring without any `-H` flag, with just `-H` (see commit below), and with `-H1G` or some other large

Adding a "release" setting in build.mk.sample (and some other build system questions)

I'm trying to figure out how to generate a release build. I thought it should be "perf" setting, but then I realized ghc-stage1 is called with -O (instead of -O2) when building stage2 with perf setting. So either perf is not the release setting, or I need stage3 which is probably compiled with
