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 1.1.1 TO 1.1.2 - -o This release fixes the bugs in PowerPC cache flushing and in - SPARC testing. - ---- - -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. - ---- - -NEWS FROM VERSION 1.0 TO 1.1 - -o Several bug fixes - -o improved infrastructure for embedding GNU lightning (lightningize - script) - ---- - -NEWS FROM VERSION 0.99 TO 1.0 - -o SPARC backend tested on GNU Smalltalk - - ---- - -NEWS FROM VERSION 0.98 TO 0.99 - -o Added floating point function support (thanks to Laurent Michel); - unfortunately this broke even more the PPC and SPARC floating point - stuff :-( - ---- - -NEWS FROM VERSION 0.97 to 0.98 - -o PPC backend tested on GNU Smalltalk - -o switched to autoconf 2.50 - -o new (much faster) PPC cache flushing code by John McIntosh - ---- - -NEWS FROM VERSION 0.96 to 0.97 - -o support for cross-assembling and for disassembling the code that the tests - generate - -o PPC microtests pass (tested directly by me), SPARC was said to work - ---- - -NEWS FROM VERSION 0.95 to 0.96 - -o fixed implementation of delay slots to be coherent with the manual - ---- - -NEWS FROM VERSION 0.94 to 0.95 - -o adc/sbc replaced with addc/addx/subc/subx to allow for more optimization - (inspired by the PPC instruction set). - -o A few fixes and much less warnings from the compiler - -o Automake-ized everything - -o i386 backend generates smaller code for bms/bmc/or/xor by using byte - or word versions if possible - -o Moved backends to separate directories - ---- - -NEWS FROM VERSION 0.93 to 0.94 - -o Manual builds as DVI file. - ---- - -NEWS FROM VERSION 0.92 to 0.93 - -o Floating-point front-end (began supporting PPC & SPARC). - ---- - -NEWS FROM VERSION 0.91 to 0.92 - -o Floating-point front-end (only x86 supported). - ---- - -NEWS FROM VERSION 0.9 to 0.91 - -o Carrying supported in addition/subtraction. - -o insn type changed to jit_insn. - -o Misc bug fixes. - -o Reentrancy supported. - -o SPARC run-time assembler rewritten. - -o The run-time assembler can be disabled for debugging purposes. |
