Hi. I have a very quick question. Is the instruction cache flushed by the llvm jit before code in memory is written to or executed? I'm assuming so, but I can't find where in the source code this is happening. In particular I searched for clflush, invd, and wbinvd instructions, but couldn't find them. And if it's not necessary to do this, can you please explain why? (I'm

...ff, is there common code out there or in the dll that will allow me to walk through x86 instructions in search for a call?

Hi. I have more questions regarding llvm and using it as a jit for our purposes. Also, let me confess that I haven't actually used llvm yet (I'm still prototyping using gnu's libjit). Some of the issues that have come up from that work so far leads to me these questions: 1) We intend to use llvm as a jit in our expression compiler at compile-time only. At runtime, the x86 code

Hi. I'm very new to LLVM, and have read some of the documentation online. Before I invest too much time, however, in learning about LLVM, I'd like to know if it can be used for my purpose. We currently have a critical runtime component that evaluates expressions via interpretation. The bytecode that we generate goes through various optimization phases similarly to that of optimizing
