Thanks for the reply. I was able to figure out the problem in 'lli'. InitializeNativeTargetAsmParser() was missing in lli.
I should have replied back saying that the problem was resolved. Hope I didn't waste your time.

You're not doing anything wrong. This is an error in 'lli' not properly initializing the native target libraries. Fixed in SVN trunk r167392.

I am first year PhD student at Stony Brook University. For one of my projects I am trying to JIT compile and run a C program containing inline assembly using MCJIT but I am not able to.
I have cloned and build LLVM-3.1. Below are more details.
Arch : x86
OS : Linux ubuntu 2.6.35-22-generic
Sample program : test_inline_asm.c
__asm __volatile("movl $5,%%eax\t"
"\n movl %%eax,%0":"=r"(a)::"cc","memory"
clang -emit-llvm -S test_inline_asm.c
lli -use-mcjit test_inline_asm.s
LLVM ERROR: Inline asm not supported by this streamer because we don't have an asm parser for this target
Any pointers to what mistake I have been doing.Any help would be much appreciated.
Thanks & Regards,
