Extended Description

Given the three attached files, this sequence of commands should show the problem:

[tomas@myhost llbug1]$ llvm-as bug1.ll
[tomas@myhost llbug1]$ llvm-as bug2.ll
[tomas@myhost llbug1]$ gcc bug.c -c
[tomas@myhost llbug1]$ llvm-ld -native -o=first bug1.bc bug2.bc bug.o
[tomas@myhost llbug1]$ ./first
42 123
[tomas@myhost llbug1]$ llvm-ar rsv bug.a bug2.bc bug.o
llvm-ar: creating bug.a
[tomas@myhost llbug1]$ llvm-ld -native -o=second bug1.bc bug.a
/tmp/ccy317Eb.o: In function main': (.text+0x5): undefined reference to getint_c'
collect2: ld returned 1 exit status
llvm-ld:
[tomas@myhost llbug1]$

would be really nice if this worked!

I should note that I use LLVM from svn rev.45924 running on X86-64 ArchLinux

We don't plan to extend llvm-ld to support this. Doing so would require it to understand tons of details of native .o formats. It is better to extend your native linker to use liblto.
