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. | |
| 40 | ||

| 42 | ||
| 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 | ||
| 66 | ||

| 68 | ||
| 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. | |

| 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. | |
