<br>
I've built a GHC with profiling enabled as guided by the wiki and that <br>
works fine standalone. I found the option for specifying a certain GHC <br>
to Cabal. But I'm a little baffled as to how to get the results of the <br>
GHC profile when building a library with Cabal.<br>
<br>
My goal is to try to get a baseline profile, then have a poke at the <br>
innards of GHC and then see if whatever I've changed has made an <br>
improvement to the build speed.<br>
<br>
Does anyone have any idea what the best way to do that is?<br>
<br>
Thanks,<br>
Sean.<br>
