Ok, I am developing an intrinsic instruction and I have the codegen working (and tested). However, some of the more complex cases of the intrinsic are reducable to LLVM + simpler cases of the intrinsic. How would I go about conditionally reducing the intrinsic? I could deal with the issue in the codegen, but that gets ugly quickly. Andrew -------------- next part -------------- A non-text

...with codegen for linux/x86. It seemed a missing peice in having a pure llvm compiled userland (mostly, being able to have a full bytecode glibc). On x86, syscalls with 5 and few args are passed in registers, but for >6, all args (except syscall number) go in a memory block passed as the first argutment. I wasn't sure if when I generate code I could safely manipulate the stack pointer (that it was gaurentied to be correct) at the point I was inserting instructions. If so, then I can add the >6 case directly to the codegen. Anyway, attached is some sample assembly output from a simpl...
