...T, I don't know of any work having been done to make the interpreter thread-safe. By the way, the interpreter can't support many more things, such as qsort() or any method which expects to call a function pointer. Is there a reason you need to use the interpreter? It's been largely undermaintained because it's pretty much useless when you've got a working JIT.

Hi Nick: The first problem have been solved by calling llvm-ld: $ llvm-ld -o hellosin.llvm hellosin.bc -lm $ lli -force-interpreter=true -load=/usr/lib/libm.so hellosin.llvm.bc hello sin: 0.50 The pthread problem remains after llvm-ld: $ lli -force-interpreter=true -load=/lib/libpthread.so.0 phello.llvm.bc 0 lli 0x08796bf8 Segmentation fault For those who are getting "invalid

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
