GNU lightning is a library to aid in making portable programs
that compile assembly code at run time.


Download release:

  2.1.0 adds the new jit_frame and jit_tramp calls, that makes
it easier to implement trampolines, tail call optimization and


  o Implement and use mcrxr emulation by default.
  o Add support for little endian.

  o Correct constants pool offset check.
  o Correct inconsistencies with ldrd and strd.

  o Add support for the 32 bit abi.

  o Add support for the x32 abi.
  o Update the x86 backend to work on cygwin64 and 32 bit cygwin.

  o Correct a bug in the redundancy optimization simplify_stxi
    function, that was making a wrong test comparing a registers
    with an immediate offset.
  o Implement jit_putarg*, that, with jit_getarg* allow read/write
    access to function arguments.
  o Implement typed jit_htonr* interfaces, to byte swap 2, 4 or
    8 byte integers.
  o Implement jit_rsb*. That generates "immediate - register"
    in an optimized format in some ports, on others it is just
    an useful alias.
  o Implement jit_align, that accepts a value up to wordsize and
    align code generation as appropriate.
  o Only mark callee save regs as live on indirect jumps. That is,
    indirect jumps are now treated as a function call.
