#define _SLJIT_CONFIG_INTERNAL_H_
/*
- SLJIT defines the following macros depending on the target architecture:
-
- Feature detection (boolean) macros:
- SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
- SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
- SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index
- SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing a double array by index
- SLJIT_LITTLE_ENDIAN : little endian architecture
- SLJIT_BIG_ENDIAN : big endian architecture
- SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
- SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
- SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address
-
- Types and useful macros:
- sljit_sb, sljit_ub : signed and unsigned 8 bit byte
- sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type
- sljit_si, sljit_ui : signed and unsigned 32 bit integer type
- sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer
- sljit_p : unsgined pointer value (usually the same as sljit_uw, but
- some 64 bit ABIs may use 32 bit pointers)
- sljit_s : single precision floating point value
- sljit_d : double precision floating point value
- SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
- SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)
+ SLJIT defines the following architecture dependent types and macros:
+
+ Types:

+ some 64 bit ABIs may use 32 bit pointers)
+ sljit_f32 : 32 bit single precision floating point value
+ sljit_f64 : 64 bit double precision floating point value
+
+ Macros for feature detection (boolean):
+ SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
+ SLJIT_64BIT_ARCHITECTURE : 64 bit architecture

+
+ Constants:
