lightning.git - Portable just-in-time compiler library

Implement a simple compare and swap atomic operation.

* lib/jit_fallback.c: Implement fallback compare and swap with pthreads. * check/Makefile.am: Update for new cas{r,i} simple test. * check/catomic.c, check/catomic.ok: New test case for simple compare and swap atomic operation. * check/lightning.c: Add entries to be able to use the new compare and swap atomic operation. Still missing a general test, only the basic C version. * include/lightning.h.in: Include pthread.h, even if not needing a fallback compare and swap. * include/lightning/jit_private.h: Add support for a register pair in second argument. Required by the new casr and casi operations. * lib/jit_aarch64-cpu.c, lib/jit_aarch64-sz.c, lib/jit_aarch64.c, lib/jit_ppc-cpu.c, lib/jit_ppc-sz.c, lib/jit_ppc.c, lib/jit_x86-cpu.c, lib/jit_x86-sz.c, lib/jit_x86.c: Implement inline code for compare and swap. * lib/jit_arm-cpu.c, lib/jit_arm-sz.c, lib/jit_arm.c: Implement inline code for compare and swap if cpu is armv7, otherwise, use a fallback with pthreads. * lib/jit_alpha-cpu.c, lib/jit_alpha-sz.c, lib/jit_alpha.c, lib/jit_hppa-cpu.c, lib/jit_hppa-sz.c, lib/jit_hppa.c, lib/jit_ia64-cpu.c, lib/jit_ia64-sz.c, lib/jit_ia64.c, lib/jit_mips-cpu.c, lib/jit_mips-sz.c, lib/jit_mips.c, lib/jit_riscv-cpu.c, lib/jit_riscv-sz.c, lib/jit_riscv.c, lib/jit_s390-cpu.c, lib/jit_s390-sz.c, lib/jit_s390.c, lib/jit_sparc-cpu.c, lib/jit_sparc-sz.c, lib/jit_sparc.c: Implement fallback compare and swap with pthreads. At least some of these should be updated for inline code generation. * lib/jit_names.c, lib/jit_print.c: lib/lightning.c: Update for the new compare and swap operation. * doc/body.texi: Add simple documentation of the compare and swap new operation.
