GNU lightning 2.1.4 released!

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-2.1.4.tar.gz

  2.1.4 main features are the new Loongarch port, currently supporting
only Linux 64 bit, and a new rewrite of the register live and
unknown state logic. Now it should be faster to generate code.

The matrix of built and tested environments is:
aarch64 Linux
alpha Linux (QEMU)
armv7l Linux (QEMU)
armv7hl Linux (QEMU)
hppa Linux (32 bit, QEMU)
i686 Linux, FreeBSD, NetBSD, OpenBSD and Cygwin/MingW
ia64 Linux
mips Linux
powerpc32 AIX
powerpc64 AIX
powerpc64le Linux
riscv Linux
s390 Linux
s390x Linux
sparc Linux
sparc64 Linux
x32 Linux
x86_64 Linux and Cygwin/MingW

  Highlights are:

• Faster jit generation.
• New loongarch port.
• New skip instruction and rework of the align instruction.
• New bswapr_us, bswapr_ui, bswapr_ul byte swap instructions.
• New movzr and movnr conditional move instructions.
• New casr and casi atomic compare and swap instructions.
• Use short unconditional jumps and calls to forward, not yet defined labels.
• And several bug fixes and optimizations.
