1 This file is the short summary of the API changes:
3 27.03.2017 - Non-backward compatible
4 JIT stack is changed from bottom-up to top-town.
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.
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.
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.
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)
30 18.05.2015 - Non-backward compatible
31 SLJIT_[I|]L[U|S]DIV is renamed to SLJIT_[I|][U|S]DIVMOD
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
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).
43 11.08.2014 - Non-backward compatible
44 A currently unused options parameter is added to sljit_emit_enter
45 and sljit_set_context.
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
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
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
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.
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.
72 08.11.2012 - Non-backward compatible
73 SLJIT_TEMPORARY_REGx registers are renamed to SLJIT_SCRATCH_REGx.
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.
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.
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.
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.
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.
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.
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.
