NEWS FROM 1.99 TO 1.99a

Lightning now builds and pass all test cases on AIX 7.1 powerpc, HP-UX 11iv2 hppa, HP-UX 11iv3 ia64, Solaris 10 Sparc, Solaris 11 x86_64, and Irix 6.5.30 mips (using n32 abi).


The 1.99 version is a major lightning redesign and an alpha version.

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 programmers, and also more natural to implement for architectures that pass arguments in registers and have alignment constraints, usually for 64 bit double arguments.

Add mips backend, implementing the o32 abi.

Added arm backend implementing all combinations of software float, vfp, neon, arm and thumb instruction sets, softfp and hardp abis, armv5, armv6, and armv7.

Added sse2+ code generation for the 32 bit x86 backend.

Added sse3 and sse4.x optional code generation for the 64 bit x86 backend, code generation based on detected cpu.

Reworked and added full lightning instruction set to ppc 32; tested on ppc64 hardware and Darwin 32 operating system.

Added ppc64 backend, built and tested on Fedora ppc.

Reworked the sparc backend, built and tested on Debian sparc.

Added an ia64 backend, built and tested on Debian ia64.

Added an hppa backend, built and tested on Debian hppa.
