1 This file is the short summary of the API changes:
3 06.05.2017 - Non-backward compatible
4 Src argument is removed from sljit_emit_op_flags.
6 24.04.2017 - Non-backward compatible
7 The sljit_is_fpu_available function is replaced
8 by sljit_has_cpu_feature.
10 20.04.2017 - Non-backward compatible
11 x86 specific cmov is changed to a general function
13 27.03.2017 - Non-backward compatible
14 JIT stack is changed from bottom-up to top-town.
16 15.01.2017 - Non-backward compatible
17 Move with update may modifiy flags, the base register
18 can only be used once and [reg+reg<<shift] addressing
19 mode where shift > 0 is not supported anymore.
21 12.01.2017 - Non-backward compatible
22 Introducing a new flag mechanism which provides better
23 compatibility with CPUs without flags. Only two flags
24 remain: zero and variable. The current type of the
25 variable flag is specified by the arithmetic operator.
26 The SLJIT_KEEP_FLAGS is removed.
28 29.02.2016 - Non-backward compatible
29 Several types and instructions are renamed to improve
30 readability. In general byte, half, and int are renamed
31 to 8, 16, and 32. Floating point types are also renamed
32 from d and s to f64 and f32.
34 [s|u]b -> [s|u]8 (8 bit values)
35 [s|u]h -> [s|u]16 (16 bit values)
36 [s|u]i -> [s|u]32 (32 bit values)
37 d -> f64 (64 bit floating point value)
38 s -> f32 (32 bit floating point value)
40 18.05.2015 - Non-backward compatible
41 SLJIT_[I|]L[U|S]DIV is renamed to SLJIT_[I|][U|S]DIVMOD
43 29.09.2014 - Non-backward compatible
44 The sljit_create_compiler, sljit_allocate_stack, and
45 sljit_free_stack functions have an allocator_data
48 19.09.2014 - Non-backward compatible
49 Using I, D, S prefixes in conditional and floating
50 point operations. And an L prefix to long multiplication
51 and division (op0 opcodes).
53 11.08.2014 - Non-backward compatible
54 A currently unused options parameter is added to sljit_emit_enter
55 and sljit_set_context.
57 06.07.2014 - Non-backward compatible
58 SCRATCH registers are renamed to Rx and SAVED registers
59 are renamed to Sx. See the explanation of these registers
62 31.05.2014 - Non-backward compatible
63 SLJIT_TEMPORARY_EREGx registers were not renamed to
64 SLJIT_SCRATCH_EREGx when the change was done on 08.11.2012
66 05.03.2014 - Backward compatible
67 The sljit_set_target now supports those jumps, which
68 does not created with SLJIT_REWRITABLE_JUMP flag.
69 Reason: sljit_emit_ijump does not support conditional
72 03.03.2014 - Non-backward compatible
73 SLJIT_MOV_UI cannot be combined with SLJIT_INT_OP.
74 Reason: SLJIT_INT_OP flag is not recommended to use
75 directly, and SLJIT_IMOV has no sign bit.
77 29.01.2014 - Backward compatible
78 Bits assigned to SLJIT_MEM and SLJIT_IMM flags are changed.
79 Reason: the most common cases are fits into one byte now,
80 and more registers can be supported in the future.
82 08.11.2012 - Non-backward compatible
83 SLJIT_TEMPORARY_REGx registers are renamed to SLJIT_SCRATCH_REGx.
85 07.11.2012 - Non-backward compatible
86 sljit_emit_cond_value is renamed to sljit_emit_op_flags. An
87 extra source argument is added which will be used in the future.
89 05.11.2012 - Backward compatible
90 sljit_emit_cond_value now supports SLJIT_AND and SLJIT_INT_OP
91 flags, which makes this function complete.
93 01.11.2012 - Non-backward compatible
94 SLJIT_F* opcodes are renamed to SLJIT_*D to show that
95 they are double precision operators. Furthermore
96 SLJIT_*S single precision opcodes are added.
98 01.11.2012 - Non-backward compatible
99 Register arguments of operations with SLJIT_INT_OP flag
100 must be computed by another operation with SLJIT_INT_OP flag.
101 The same way as SLJIT_SINGLE_OP flag works with floating point
102 numbers. See the description of SLJIT_INT_OP.
104 01.11.2012 - Backward compatible
105 All operations whose support the SLJIT_INT_OP flag, have an
106 alternate name now, which includes the SLJIT_INT_OP. These
107 names starting with I.
109 31.10.2012 - Non-backward compatible
110 Renaming sljit_w to sljit_sw, sljit_i to sljit_si, sljit_h
111 to sljit_sh, and sljit_b to sljit_sb. Reason: their sign
112 bit is part of the type now.
114 20.10.2012 - Non-backward compatible
115 Renaming SLJIT_C_FLOAT_NAN to SLJIT_C_FLOAT_UNORDERED.
116 Reason: all architectures call these unordered comparions.
