NEWS FROM 1.99 TO 1.99a |
|
|
|
o 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). |
|
|
|
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 |
|
|
|
o Initial support for x86-64 back-end (mostly untested). |
|
|
|
o lightning is more strict on casts from integer to pointer. |
|
Be sure to use the _p variants when your immediates are |
|
of pointer type. This was done to ease 64-bit cleanliness |
|
tests. |
|
|
|
o Many bug fixes. |
|
|
|
o JIT_FPRET is used as JIT_RET to move return values. |
|
jit_retval_[fd] is used to retrieve return values. |
|
|
|
o jit_pushr/jit_popr are deprecated, you need to #define |
|
JIT_NEED_PUSH_POP prior to including lightning.h if you |
|
want to use them. |
|
|
|
o Support for stack-allocated variables. Because of this, |
|
backends defining JIT_FP should now rename it to JIT_AP. |
|
JIT_FP is now a user-visible register used in ldxi/ldxr |
|
to access stack-allocated variables. |
|
|
|
|
|
|
|
|
|
NEWS FROM VERSION 1.1.2 TO 1.2 |
|
|
|
o Floating-point interface rewritten, uses a register file |
|
architecture rather than a stack. |
|
|
|
o Many bug fixes. |
|
|
|
o jit_prepare and jit_retval are now jit_prepare_i and |
|
jit_retval_i. |
|
|
|
o Support for Fedora Core 1's exec-shield feature. |
|
|
|
o PPC supports both SysV and Darwin ABIs. |
|
|
|
o More (and more complete) examples provided. |

o Merge changes from Debian |

This version was released to have a distributable version of lightning |

after the recent crack of the GNU FTP machines. It does not fix |
|
outstanding bugs; I apologize for the inconvenience. |
