llvmpipe: add a new JIT engine based on LLVM ORCJIT, also add RISC-V support (updated)
This MR contains updates of multiple previous commits to implement ORCJIT, a new JIT engine from LLVM, to provide support for new architectures.
Original commits come from @alexfanqi in these MRs, however, the original author doesn't seems to be updating anymore:
- !17801 (closed) Draft: llvmpipe: add a new jit engine based on llvm orcjit, also add in riscv support
Some changes in lp_bld_init.c (MCJIT) have also been synchronized to lp_bld_init_orc.cpp (ORCJIT).
A meson option llvm-orcjit is introduced to enable ORCJIT support. (Disabled by default)
I've tested on PineTab-V (JH7110 RISC-V) with glxgears and glmark2 (score: 10). More tests and benchmarks are welcomed.
I've tested on Visionfive2(JH7110), LicheePi 4A(TH1520), Sophgo Mango(SG2042). It works.
