+       * 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.

+
+       * 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.

+
+       * 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.

        * lib/jit_fallback.c: Implement fallback compare and swap with
