+ of the input and the result registers are not defined by SLJIT, it might

+ requirements all source registers must be the result of those operations

+ mixed. The only exception is SLJIT_MOV32 which source register can hold
+ any 32 or 64 bit value, and it is converted to a 32 bit compatible format
+ first. When the source and destination registers are the same, this
+ conversion is free (no instructions are emitted) on most CPUs. A 32 bit
+ value can also be converted to a 64 bit value by SLJIT_MOV_S32
+ (sign extension) or SLJIT_MOV_U32 (zero extension).
+
+ As for floating-point operations, this option sets 32 bit single
+ precision mode. Similar to the integer operations, all register arguments
+ must be the result of those operations where this option was also set.
+
+ Note: memory addressing always uses 64 bit values on 64 bit systems so
+ the result of a 32 bit operation must not be used with SLJIT_MEMx
+ macros.
+
+ This option is part of the instruction name, so there is no need to
+ manually set it. E.g:
