+ * include/lightning/jit_loongarch.h, lib/jit_loongarch-cpu.c,
+ lib/jit_loongarch-fpu.c, lib/jit_loongarch-sz.c, lib/jit_loongarch.c:
+ New files implementing the first version of the new loongarch port.
+ * check/float.tst: Add preprocessor checks for NaN and +-Inf
+ values converted to integers for loongarch.
+ * configure.ac: Add check and conditionals for new architecture.
+ * include/lightning.h.in, check/lightning.c,
+ include/lightning/Makefile.am, include/lightning/jit_private.h,
+ lib/Makefile.am, lib/jit_size.c, lib/lightning.c: Update for new
+ port.

+
+ * check/lightning.c: Remove -Dmacro=value from usage and attempt
+ to parse it. It was buggy and not properly implemented. Now
+ it pass any extra options to the generated jit. To pass any
+ option starting with '-' need to also use '--'.
+ * check/collatz.e: New sample file showing an example of jit
+ generation.
+
+2022-10-04 Paulo Andrade <pcpa@gnu.org>
+
+ * include/lightning/jit_private.h: Add new flag to jit_block_t.
+ * lib/lightning.c: Rewrite register liveness and state at block
+ entry code to avoid a very expensive and non scaling code path.
+ Now it attempts to do as few as possible recomputations when
+ merging state of adjacent blocks, still doing one extra nop pass
+ (in the sense that it will not find any changes) to make sure the
+ logic is correct.
+
+2022-09-30 Paulo Andrade <pcpa@gnu.org>
+
+ * include/lightning/jit_private.h: Implement new data structures
+ specific to riscv.
+ * lib/jit_disasm.c: Extra disassemble code for riscv constant pool.
+ * lib/jit_riscv-cpu.c: Modify movi to use constant pool if 3 or
+ more instructions are required to construct constant and modify
+ movi_p to use a pc relative load from a constant pool.
+ lib/jit_riscv-sz.c: Update for new constant pool code. Most
+ instructions that need 64 bit constants are significantly reduced.
+ * lib/jit_riscv.c: Implement most of the constant pool code.
+ * lib/jit_size.c: Update for estimate of code generation size.
+ * lib/lightning.c: Update for riscv specific code, and also make
+ sure to mprotect the constant pool as executable.
+
+2022-09-08 Paulo Andrade <pcpa@gnu.org>
+
+ * 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_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.
+
+2022-08-12 Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>
+
+ Document jit_align.
+ * doc/body.texi: Add documentation for jit_align.
+
2022-05-14 Paulo Andrade <pcpa@gnu.org>
* include/lightning.h.in: Reorder jit_mov{n,z}r in instruction list.
