I get SEGV in gcc-compiled procedure in Solaris10-i386. This procedure is called from llvm JIT code. Exact instruction that crashes is this: movdqa %xmm0, 0x10(%esp) %esp is 8-aligned, and by definition of movdqa it expects 16-aligned stack. This leads me to believe that llvm uses wrong ABI when calling external procedures and doesn't align stack properly. llvm module executing in JIT has
