| | 3 | o Lightning now builds and pass all test cases on AIX 7.1 powerpc, |
| | 4 | HP-UX 11iv2 hppa, HP-UX 11iv3 ia64, Solaris 10 Sparc, Solaris 11 |
| | 5 | x86_64, and Irix 6.5.30 mips (using n32 abi). |
| | 6 | |
| | 7 | NEWS FROM VERSION 1.3 TO 1.99 |
| | 8 | |
| | 9 | o The 1.99 version is a major lightning redesign and an |
| | 10 | alpha version. |
| | 11 | |
| | 12 | o Unless for some special power users usage, the major |
| | 13 | difference in the rework is that now function calls push |
| | 14 | arguments from left to right, what is both, more natural for |
| | 15 | programers, and also more natural to implement for architectures |
| | 16 | that pass arguments in registers and have alignment constraints, |
| | 17 | usually for 64 bit double arguments. |
| | 18 | |
| | 19 | o Add mips backend, implementing the o32 abi. |
| | 20 | |
| | 21 | o Added arm backend implementing all combinations of software float, |
| | 22 | vfp, neon, arm and thumb instruction sets, softfp and hardp abis, |
| | 23 | armv5, armv6, and armv7. |
| | 24 | |
| | 25 | o Added sse2+ code generation for the 32 bit x86 backend. |
| | 26 | |
| | 27 | o Added sse3 and sse4.x optional code generation for the 64 bit |
| | 28 | x86 backend, code generation based on detected cpu. |
| | 29 | |
| | 30 | o Reworked and added full lightning instruction set to ppc 32; |
| | 31 | tested on ppc64 hardware and Darwin 32 operating system. |
| | 32 | |
| | 33 | o Added ppc64 backend, built and tested on Fedora ppc. |
| | 34 | |
| | 35 | o Reworked the sparc backend, built and tested on Debian sparc. |
| | 36 | |
| | 37 | o Added an ia64 backend, built and tested on Debian ia64. |
| | 38 | |
| | 39 | o Added an hppa backend, built and tested on Debian hppa. |

| | 43 | NEWS FROM VERSION 1.2 TO 1.3 |
| | 44 | |
| | 45 | o Initial support for x86-64 back-end (mostly untested). |
| | 46 | |
| | 47 | o lightning is more strict on casts from integer to pointer. |
| | 48 | Be sure to use the _p variants when your immediates are |
| | 49 | of pointer type. This was done to ease 64-bit cleanliness |
| | 50 | tests. |
| | 51 | |
| | 52 | o Many bug fixes. |
| | 53 | |
| | 54 | o JIT_FPRET is used as JIT_RET to move return values. |
| | 55 | jit_retval_[fd] is used to retrieve return values. |
| | 56 | |
| | 57 | o jit_pushr/jit_popr are deprecated, you need to #define |
| | 58 | JIT_NEED_PUSH_POP prior to including lightning.h if you |
| | 59 | want to use them. |
| | 60 | |
| | 61 | o Support for stack-allocated variables. Because of this, |
| | 62 | backends defining JIT_FP should now rename it to JIT_AP. |
| | 63 | JIT_FP is now a user-visible register used in ldxi/ldxr |
| | 64 | to access stack-allocated variables. |

| | 71 | o Floating-point interface rewritten, uses a register file |
| | 72 | architecture rather than a stack. |
| | 73 | |
| | 74 | o Many bug fixes. |
| | 75 | |
| | 76 | o jit_prepare and jit_retval are now jit_prepare_i and |
| | 77 | jit_retval_i. |
| | 78 | |
| | 79 | o Support for Fedora Core 1's exec-shield feature. |
| | 80 | |
| | 81 | o PPC supports both SysV and Darwin ABIs. |
| | 82 | |
| | 83 | o More (and more complete) examples provided. |
