The table which +* dispatches this is found in the files optab.[ch]. +* +* Each opcode proc has a comment preceeding it which gives it's table +* address. Several opcodes are missing (undefined) in the table. +* +* Each proc includes information for decoding (DECODE_PRINTF and +* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc +* functions (START_OF_INSTR, END_OF_INSTR). +* +* Many of the procedures are *VERY* similar in coding. This has +* allowed for a very large amount of code to be generated in a fairly +* short amount of time (i.e. cut, paste, and modify). The result is +* that much of the code below could have been folded into subroutines +* for a large reduction in size of this file. The downside would be +* that there would be a penalty in execution speed. The file could +* also have been *MUCH* larger by inlining certain functions which +* were called. This could have resulted even faster execution. The +* prime directive I used to decide whether to inline the code or to +* modularize it, was basically: 1) no unnecessary subroutine calls, +* 2) no routines more than about 200 lines in size, and 3) modularize +* any code that I might not get right the first time. The fetch_* +* subroutines fall into the latter category. The The decode_* fall +* into the second category. The coding of the "switch(mod){ .... }" +* in many of the subroutines below falls into the first category. +* Especially, the coding of {add,and,or,sub,...}_{byte,word} +* subroutines are an especially glaring case of the third guideline. +* Since so much of the code is cloned from other modules (compare +* opcode #00 to opcode #01), making the basic operations subroutine +* calls is especially important; otherwise mistakes in coding an +* "add" would represent a nightmare in maintenance. +* +* Jason ported this file to u-boot. place all the function pointer in +* the got2 sector.
