API_CHANGES revision 1.1.1.2.16.1
1 This file is the short summary of the API changes: 2 3 27.03.2017 - Non-backward compatible 4 JIT stack is changed from bottom-up to top-town. 5 6 15.01.2017 - Non-backward compatible 7 Move with update may modifiy flags, the base register 8 can only be used once and [reg+reg<<shift] addressing 9 mode where shift > 0 is not supported anymore. 10 11 12.01.2017 - Non-backward compatible 12 Introducing a new flag mechanism which provides better 13 compatibility with CPUs without flags. Only two flags 14 remain: zero and variable. The current type of the 15 variable flag is specified by the arithmetic operator. 16 The SLJIT_KEEP_FLAGS is removed. 17 18 29.02.2016 - Non-backward compatible 19 Several types and instructions are renamed to improve 20 readability. In general byte, half, and int are renamed 21 to 8, 16, and 32. Floating point types are also renamed 22 from d and s to f64 and f32. 23 24 [s|u]b -> [s|u]8 (8 bit values) 25 [s|u]h -> [s|u]16 (16 bit values) 26 [s|u]i -> [s|u]32 (32 bit values) 27 d -> f64 (64 bit floating point value) 28 s -> f32 (32 bit floating point value) 29 30 18.05.2015 - Non-backward compatible 31 SLJIT_[I|]L[U|S]DIV is renamed to SLJIT_[I|][U|S]DIVMOD 32 33 29.09.2014 - Non-backward compatible 34 The sljit_create_compiler, sljit_allocate_stack, and 35 sljit_free_stack functions have an allocator_data 36 argument now. 37 38 19.09.2014 - Non-backward compatible 39 Using I, D, S prefixes in conditional and floating 40 point operations. And an L prefix to long multiplication 41 and division (op0 opcodes). 42 43 11.08.2014 - Non-backward compatible 44 A currently unused options parameter is added to sljit_emit_enter 45 and sljit_set_context. 46 47 06.07.2014 - Non-backward compatible 48 SCRATCH registers are renamed to Rx and SAVED registers 49 are renamed to Sx. See the explanation of these registers 50 in sljitLir.h. 51 52 31.05.2014 - Non-backward compatible 53 SLJIT_TEMPORARY_EREGx registers were not renamed to 54 SLJIT_SCRATCH_EREGx when the change was done on 08.11.2012 55 56 05.03.2014 - Backward compatible 57 The sljit_set_target now supports those jumps, which 58 does not created with SLJIT_REWRITABLE_JUMP flag. 59 Reason: sljit_emit_ijump does not support conditional 60 jumps. 61 62 03.03.2014 - Non-backward compatible 63 SLJIT_MOV_UI cannot be combined with SLJIT_INT_OP. 64 Reason: SLJIT_INT_OP flag is not recommended to use 65 directly, and SLJIT_IMOV has no sign bit. 66 67 29.01.2014 - Backward compatible 68 Bits assigned to SLJIT_MEM and SLJIT_IMM flags are changed. 69 Reason: the most common cases are fits into one byte now, 70 and more registers can be supported in the future. 71 72 08.11.2012 - Non-backward compatible 73 SLJIT_TEMPORARY_REGx registers are renamed to SLJIT_SCRATCH_REGx. 74 75 07.11.2012 - Non-backward compatible 76 sljit_emit_cond_value is renamed to sljit_emit_op_flags. An 77 extra source argument is added which will be used in the future. 78 79 05.11.2012 - Backward compatible 80 sljit_emit_cond_value now supports SLJIT_AND and SLJIT_INT_OP 81 flags, which makes this function complete. 82 83 01.11.2012 - Non-backward compatible 84 SLJIT_F* opcodes are renamed to SLJIT_*D to show that 85 they are double precision operators. Furthermore 86 SLJIT_*S single precision opcodes are added. 87 88 01.11.2012 - Non-backward compatible 89 Register arguments of operations with SLJIT_INT_OP flag 90 must be computed by another operation with SLJIT_INT_OP flag. 91 The same way as SLJIT_SINGLE_OP flag works with floating point 92 numbers. See the description of SLJIT_INT_OP. 93 94 01.11.2012 - Backward compatible 95 All operations whose support the SLJIT_INT_OP flag, have an 96 alternate name now, which includes the SLJIT_INT_OP. These 97 names starting with I. 98 99 31.10.2012 - Non-backward compatible 100 Renaming sljit_w to sljit_sw, sljit_i to sljit_si, sljit_h 101 to sljit_sh, and sljit_b to sljit_sb. Reason: their sign 102 bit is part of the type now. 103 104 20.10.2012 - Non-backward compatible 105 Renaming SLJIT_C_FLOAT_NAN to SLJIT_C_FLOAT_UNORDERED. 106 Reason: all architectures call these unordered comparions. 107
