GNU lightning 2.1.0 released!

Item posted by Paulo César Pereira de Andrade <pcpa> on Sat 07 Feb 2015 07:12:27 PM UTC.

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

Development:
http://git.savannah.gnu.org/cgit/lightning.git

Download release:
ftp://ftp.gnu.org/gnu/lightning/lightning-2.1.0.tar.gz

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

------------------------------------------------------------------------

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

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

s390:
o Add support for the 32 bit abi.

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

generic:
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.
