* Top level include file provding ISA pseudo-mnemonics for use in assemmler
|

* and inline assembly.
|
||||
*
|
||||
* - Helps code reuse across ARC64/ARC32/ARCv2
|
||||
* e.g. "LDR" maps to 'LD' on 32-bit ISA, 'LDL' on 64-bit ARCv2/ARC64
|
||||
*
|
||||
* - Provides emulation with multiple instructions if the case be
|
||||
* e.g. "DBNZ" implemented using 'SUB' and 'BRNE'
|
||||
*
|
||||
* - Looks more complex than it really is: mainly because Kconfig defines
|
||||
* are not "honored" in inline assembly. So each varaint is unconditional
|
||||
* code in a standalone file with Kconfig based #ifdef'ry here. During the
|
||||
* build process, the "C" preprocessor runs through this file, leaving
|
||||
* just the final variant include in code fed to compiler/assembler.
