#2001: panic when recompiling after ctrl-C leaves .o without .hi

Priority: normal | Milestone:
Component: Compiler | Version: 6.8.2
Severity: minor | Keywords:
Difficulty: Unknown | Testcase:
Architecture: x86 | Os: Linux
-----------------------------+----------------------------------------------
I was just doing some GHC hacking, and I typed Ctrl-C to interrupt a
compilation just after it output some warnings. When I tried to repeat
the compilation so it would finish...
{{{
Panic! stage1/cmm/CmmSpillReload.o exists, but
stage1/cmm/CmmSpillReload.hi does not.
}}}
This statement was true, and I removed `stage1/cmm/CmmSpillReload.o` so
that I could recompile successfully. I think the correct GHC behavior is
not to panic, just to recompile when it doesn't find all the correct
generated files already there. (although it might indicate something that
could be different upon reacting to ctrl-C too)
