NEWS FROM VERSION 1.3 TO 1.99
o The 1.99 version is a major lightning redesign and an
alpha version.
o Unless for some special power users usage, the major
difference in the rework is that now function calls push
arguments from left to right, what is both, more natural for
programers, and also more natural to implement for architectures
that pass arguments in registers and have alignment constraints,
usually for 64 bit double arguments.
o Add mips backend, implementing the o32 abi.
o Added arm backend implementing all combinations of software float,
vfp, neon, arm and thumb instruction sets, softfp and hardp abis,
armv5, armv6, and armv7.
o Added sse2+ code generation for the 32 bit x86 backend.
o Added sse3 and sse4.x optional code generation for the 64 bit
x86 backend, code generation based on detected cpu.
o Reworked and added full lightning instruction set to ppc 32;
tested on ppc64 hardware and Darwin 32 operating system.
o Added ppc64 backend, built and tested on Fedora ppc.
o Reworked the sparc backend, built and tested on Debian sparc.
o Added an ia64 backend, built and tested on Debian ia64.
o Added an hppa backend, built and tested on Debian hppa.

NEWS FROM VERSION 1.2 TO 1.3 NEWS FROM VERSION 1.2 TO 1.3

* Update documentation to match new implementation.
* Make an sparc port to not remove previous functionality.
* Add two new base instructions to help dynamically typed
languages, that use two result registers and two argument
registers, implementing multiplication and quotient+remainder
return from division. Alternatively, can add branch codes
for multiplication that overflows (and reverse for no
overflow) and division with zero remainder or non zero
remainder.
Suggested names for now are "qmul" and "qdiv", with "r"
and "i" variants, and possibly unsigned version. Branches
would use "bo" and "bx" prefix.
* Validate that divrem in jit_x86-cpu.c is not modifying * Validate that divrem in jit_x86-cpu.c is not modifying
the non result arguments. This is not verified by clobber.tst, the non result arguments. This is not verified by clobber.tst,
as it only checks registers not involved in the operation as it only checks registers not involved in the operation
(because it does not know about values being set as input (because it does not know about values being set as input
for the the operation). for the the operation).
* Write a bytecode backend for unsupported architectures.
* Write a simple higher level language implementation generating
jit with lightning, that could be some lisp or C like language.
