1 | NEWS FROM 1.99 TO 1.99a |
2 | ||
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. | |
65 | ||

69 | NEWS FROM VERSION 1.1.2 TO 1.2 | |
70 | ||
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. | |

87 | NEWS FROM VERSION 1.1.1 TO 1.1.2 | |
88 | ||

90 | SPARC testing. | |

94 | NEWS FROM VERSION 1.1 TO 1.1.1 | |
95 | ||
96 | o Merge changes from Debian | |
97 | ||
98 | This version was released to have a distributable version of lightning | |
99 | after the recent crack of the GNU FTP machines. It does not fix | |
100 | outstanding bugs; I apologize for the inconvenience. | |
