This file is the short summary of the API changes:
16.08.2020 - Non-backward compatible
A second parameter has been added to sljit_create_compiler()
and sljit_free_code() to pass some data to the executable
allocator functions.
24.01.2020 - Non-backward compatible
The SLJIT_MOV instructions does not support SLJIT_UNDEFINED
as destination. New prefetch instructions has been added
instead.
20.01.2019 - Non-backward compatible
The check_sljit_emit_fast_return function is removed, and
this operation is available through check_sljit_emit_op_src.
16.01.2019 - Backward compatible
A new opcode (SLJIT_ENDBR) is added to support
Intel Control-flow Enforcement Technology (CET).
08.01.2018 - Non-backward compatible
Fields of sljit_stack are renamed to fit a
top-down stack better.
02.01.2018 - Non-backward compatible
Immediate source argument has not been supported
for NOT, NEG, CLZ, and fast_return instructions
anymore. No CPU supports immedate arguments for
these opcodes.
26.12.2017 - Non-backward compatible
The MOVU opcodes are removed because the emulation
is inefficient. The sljit_emit_mem() operation is
added instead.
18.10.2017 - Non-backward compatible
The SLJIT_CALL0 - SLJIT_CALL3 jump types are
replaced by sljit_emit_call and sljit_emit_icall
function calls. These functions allows declaring
the argument types.
06.05.2017 - Non-backward compatible
Src argument is removed from sljit_emit_op_flags.
24.04.2017 - Non-backward compatible
The sljit_is_fpu_available function is replaced
by sljit_has_cpu_feature.
20.04.2017 - Non-backward compatible
x86 specific cmov is changed to a general function
27.03.2017 - Non-backward compatible
JIT stack is changed from bottom-up to top-town.
15.01.2017 - Non-backward compatible
Move with update may modifiy flags, the base register
can only be used once and [reg+reg<<shift] addressing
mode where shift > 0 is not supported anymore.
12.01.2017 - Non-backward compatible
Introducing a new flag mechanism which provides better
compatibility with CPUs without flags. Only two flags
remain: zero and variable. The current type of the
variable flag is specified by the arithmetic operator.
The SLJIT_KEEP_FLAGS is removed.
29.02.2016 - Non-backward compatible
Several types and instructions are renamed to improve
readability. In general byte, half, and int are renamed
to 8, 16, and 32. Floating point types are also renamed
from d and s to f64 and f32.
[s|u]b -> [s|u]8 (8 bit values)
[s|u]h -> [s|u]16 (16 bit values)
[s|u]i -> [s|u]32 (32 bit values)
d -> f64 (64 bit floating point value)
s -> f32 (32 bit floating point value)
18.05.2015 - Non-backward compatible
SLJIT_[I|]L[U|S]DIV is renamed to SLJIT_[I|][U|S]DIVMOD
29.09.2014 - Non-backward compatible
The sljit_create_compiler, sljit_allocate_stack, and
sljit_free_stack functions have an allocator_data
argument now.
19.09.2014 - Non-backward compatible
Using I, D, S prefixes in conditional and floating
point operations. And an L prefix to long multiplication
and division (op0 opcodes).
11.08.2014 - Non-backward compatible
A currently unused options parameter is added to sljit_emit_enter
and sljit_set_context.
06.07.2014 - Non-backward compatible
SCRATCH registers are renamed to Rx and SAVED registers
are renamed to Sx. See the explanation of these registers
in sljitLir.h.
31.05.2014 - Non-backward compatible
SLJIT_TEMPORARY_EREGx registers were not renamed to
SLJIT_SCRATCH_EREGx when the change was done on 08.11.2012
05.03.2014 - Backward compatible
The sljit_set_target now supports those jumps, which
does not created with SLJIT_REWRITABLE_JUMP flag.
Reason: sljit_emit_ijump does not support conditional
jumps.
03.03.2014 - Non-backward compatible
SLJIT_MOV_UI cannot be combined with SLJIT_INT_OP.
Reason: SLJIT_INT_OP flag is not recommended to use
directly, and SLJIT_IMOV has no sign bit.
29.01.2014 - Backward compatible
Bits assigned to SLJIT_MEM and SLJIT_IMM flags are changed.
Reason: the most common cases are fits into one byte now,
and more registers can be supported in the future.
08.11.2012 - Non-backward compatible
SLJIT_TEMPORARY_REGx registers are renamed to SLJIT_SCRATCH_REGx.
07.11.2012 - Non-backward compatible
sljit_emit_cond_value is renamed to sljit_emit_op_flags. An
extra source argument is added which will be used in the future.
05.11.2012 - Backward compatible
sljit_emit_cond_value now supports SLJIT_AND and SLJIT_INT_OP
flags, which makes this function complete.
01.11.2012 - Non-backward compatible
SLJIT_F* opcodes are renamed to SLJIT_*D to show that
they are double precision operators. Furthermore
SLJIT_*S single precision opcodes are added.
01.11.2012 - Non-backward compatible
Register arguments of operations with SLJIT_INT_OP flag
must be computed by another operation with SLJIT_INT_OP flag.
The same way as SLJIT_SINGLE_OP flag works with floating point
numbers. See the description of SLJIT_INT_OP.
01.11.2012 - Backward compatible
All operations whose support the SLJIT_INT_OP flag, have an
alternate name now, which includes the SLJIT_INT_OP. These
names starting with I.
31.10.2012 - Non-backward compatible
Renaming sljit_w to sljit_sw, sljit_i to sljit_si, sljit_h
to sljit_sh, and sljit_b to sljit_sb. Reason: their sign
bit is part of the type now.
20.10.2012 - Non-backward compatible
Renaming SLJIT_C_FLOAT_NAN to SLJIT_C_FLOAT_UNORDERED.
Reason: all architectures call these unordered comparions.
