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.

NEWS FROM VERSION 1.1 TO 1.1.1
|
|
|
|
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.
