Hi Nick: Thanks for pointing me to libffi. Recompile LLVM with libffi does solve the problem of printf. But it still has other problems: 1) sinf() returns 0 in the interpreter, but returns correct value in JIT (see hellosin.c) 2) calling pthread_create cause lli to crash in the interpreter mode, but no problem in JIT (see phello.c). My questions are: i) can I call any arbitrary external function

Hi: When I try to execute lli -force-interpreter=true hello.bc, it gave the following error: LLVM ERROR: Tried to execute an unknown external function: i32 (i8*)* puts I think the error is because C library is not being linked with the byte code, but I was not able to find any helpful instruction in lli's document. Can you please teach me how to do it? Thanks Xu The hello.bc is
