kandi X-RAY | sljit Summary

sljit is a C library typically used in Utilities, Compiler applications. sljit has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

SLJIT - Stack Less JIT Compiler. Purpose: A simple, machine independent JIT compiler, which suitable for translating interpreted byte code to machine code. The sljitLir.h describes the LIR (low-level intermediate representation) of SLJIT. Compatible: Any modern C (C++) compiler. At least I hope so. Using sljit: Copy the content of sljit_src directory into your project source directory. Add sljitLir.c source file to your build environment. All other files are included by sljitLir.c (if required). Define the machine by SLJIT_CONFIG_* selector. See sljitConfig.h for all possible values. For C++ compilers, rename sljitLir.c to sljitLir.cpp. Special thanks: Alexander Nasonov Daniel Richard G. Giuseppe D'Angelo Jiong Wang (TileGX support).

Why does powerpc need this additional fluff to make a raw machine code function work?

QUESTION

Why does powerpc need this additional fluff to make a raw machine code function work?

Asked 2019-Mar-25 at 19:28

I'm working on a simple JIT compiler for PowerPC, I followed the examples in https://github.com/spencertipping/jit-tutorial to get a hang of how to work with it.

The problem is that the identity function in the second example "jitproto.c" can't really be ported to powerpc as is, using the "LWA" and "BLR" instructions, it just causes segfaults when executed.

In the end I used the machine code output of the SLJIT compiler (https://github.com/linux-on-ibm-z/sljit) to see what I'm doing wrong, and I see it generates 12 instruction words before what I thought would be the function.

So what are those instructions doing? Why can't I just start the function directly like in x86?

Code can be compiled with a C99 compiler on PPC64 (tested in a powermac and a power8 server).

The instructions are required for setting up the stack layout of PPC64 ABI. See here: http://refspecs.linuxfoundation.org/ELF/ppc64/PPC-elf64abi.html#STACK
