+
+ * 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.
