* include/lightning.h: Add check for __powerpc__ defined in Linux, while Darwin defines __ppc__. * include/lightning/jit_ppc.h: Adjust register definitions for Darwin 32 bit and Linux 64 bit ppc usage and/or ABI. * include/lightning/jit_private.h: Add proper check for Linux __powerpc__ and an data definition for an workaround to properly handle code that starts with a jump to a "main" label. * lib/jit_disasm.c: Add extra disassembler initialization for __powerpc64__. * lib/jit_ppc-cpu.c: Add extra macros and functions, and correct/adapt previous ones to handle powerpc64. * lib/jit_ppc-fpu.c: Adapt for 64 bit wordsize. Basically add conversion from/to int32/int64 and proper handling of load/store offsets too large for 32 bit. * lib/jit_ppc.c: Add calls to 64 bit codes and adaptation for the PowerPC 64 bit Linux ABI. * lib/jit_arm.c, lib/jit_mips.c, lib/jit_sparc, lib/jit_x86.c, lib/lightning.c: Correct off by one error when restarting jit of a function due to finding too late that needs to spill/reload some register. Problem was found by accident on a very special condition during PowerPC 64 code adaptation.
