Comment(by batterseapower):
Well, the "fast" testsuite basically works, with the exception of some of
the GHC performance tests (and ffi005 which I have never seen pass on any
of my OS X machines). This is encouraging, but I need to look carefully at
the performance tests.
I'm not having much luck with providing a way to strip out the debug info.
I played with the suggestion by Simon to have an optionally-strippable
section, but:
* OS X strip has no option to strip sections with a given name
* If I install GNU strip using Macports, trying to strip anything
produces by GHC causes the stripped thing to die immediately upon running
with "Illegal instruction". gstrip itself complains about "unable to read
unknown load command 0x22". I have no idea what to make of that.
Which is kind of discouraging. Even if I got it all working on every
platform, we would never be able to strip the .ghc_debug section from
shared libraries, which is sort of annoying.
I guess I could probably stuff the info into a normally-named .debug
section, and then just run plain "strip" on the result if you have
requested that stack traces be disabled. This might be annoying for those
who link in their own .o files with debug info they want to preserve, but
maybe that is an acceptable tradeoff. Thoughts?
