[LLVMdev] Bitcode not portable from linux to solaris?

[Lally Singh]

To answer my own question.  The problem is that Solaris ships with
very old tools, and llvmc was generating assembler that worked with a
fresh (gcc-4.5) compile & install.  I had them handy, just further
down the path.  Hopefully anyone with the same problem can find this
in the archive.



Thanks everyone.
