[LLVMdev] Unable to Run Inline Asm with MCJIT

[Amit Arya]

Hi,

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
-------------------
#include <stdio.h>
int main(){
    int a=0;
    __asm __volatile("movl $5,%%eax\t"
    "\n movl %%eax,%0":"=r"(a)::"cc","memory"
    );
    printf("a= %d\n",a);
}

Commands
-------------
clang -emit-llvm -S test_inline_asm.c
lli -use-mcjit test_inline_asm.s

throws,

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,
Amit Arya
