Created an attachment (id=3087)
 --> (http://llvm.org/bugs/attachment.cgi?id=3087)
Contains three files, rng.cpp, rng.h, annealer_thread.cpp

The source files come from a PARSEC benchmark.

When I emit llvm bitcode and then assemble native code I get the following
error:
+ llvm-g++ -emit-llvm annealer_thread.cpp -c -o annealer_thread.o
+ llvm-g++ -emit-llvm rng.cpp -c -o rng.o
+ llc annealer_thread.o -f -o annealer_thread.s
+ llvm-g++ -c annealer_thread.s -o annealer_thread.o
+ llc rng.o -f -o rng.s
+ llvm-g++ -c rng.s -o rng.o
+ llvm-g++ annealer_thread.o rng.o
rng.o: In function `MTRand::reload()':
rng.s:(.text+0x50): multiple definition of `MTRand::reload()'
annealer_thread.o:annealer_thread.s:(.text+0xa0): first defined here
collect2: ld returned 1 exit status

When I don't everything works:
+ llvm-g++ annealer_thread.cpp -c -o annealer_thread.o
+ llvm-g++ rng.cpp -c -o rng.o
+ llvm-g++ rng.o annealer_thread.o
