llc assertion failure

Ryan M. Lefever
I am running the following llvm-ld command to produce native code:

llvm-ld -native -o code.exe code.bc   -lm

However, I am getting the following assertion failure in llc.  The
bytecode has been processed with opt, it passes opt bytecode
verification.  I'm not too familiar with backend code generation.  Does
anyone have any insight in to what the problem might be or how to go
about debugging it?

Regards,
Ryan

Hi Ryan,

Okay, a couple things:

1. Does the llc version match the llvm-gcc or whatever frontend that
   produced "code.bc". This could simply be an IR version issue if
   you're working on CVS HEAD. If that's not it, then ...

2. This looks to be an llc problem not llvm-ld. All that is happening
   here is that llvm-ld is exec'ing llc on code.bc. Could you please
   run llc under the debugger and give it code.bc as input. When it
   fails, please get a stack trace and then create a PR for this
   problem.

Thanks,

Reid.

Re: llc assertion failure

Ryan M. Lefever
Is a PR a bug report on the bugzilla database?  I am also running
bugpoint to see if that yields anything.

Yes, so named because of the URL translation. I.e. http://llvm.org/PR123
takes you to bugzilla bug 123. PR == Problem Report.

Okay, good. That might turn up something useful. If you suspect its a
bug, please file the stack trace and reduced test case in a new PR.

Thanks, Ryan.

Re: llc assertion failure

Ryan M. Lefever
Reid,

I have filed the llc assertion failure as a new bug report.  I attached
the offending bytecode, and the results of running bugpoint.

Thanks,
Ryan
