[LLVMdev] Bitcode not portable from linux to solaris?

[Lally Singh]

Hi all.

  I made some early experiments --- namely a llvm program that
printf'd "hello world" -- that seemed to indicate that a bitcode file
I generate on linux would work on my solaris box.  Well, they're
actually the same machine, an amd opteron sun box with a linux vm
running.   My generating program doesn't run on solaris, but I was
hoping to generate bitcode for it from linux.  lli crashes pretty
quick (although the same use on linux has been debugged pretty well,
and it's a pretty simple program!).  llvmc -clang complains quite a
bit about invalid directives (sorry, couldn't get on the machine
before my commute to work, so this is from memory only).

I read something quite some time ago that perhaps the bitcode wasn't
portable if the machines had different pointer sizes.  Solaris is
64bit (almost exclusively).  I tried generating from both 32 and 64
bit linux VMs, but perhaps I just didn't configure it properly to
generate 64-bit code?

I thought it was supposed to be portable?  Am I wrong?  llvm-dis works
on it fine.  Perhaps a llvm-dis -> llvm-as cycle would do the trick?

I can post the (small) bitcode file and the errors tonight, if that helps.

Any help is really appreciated.  Thanks in advance!
