Move print_insn_XXX to an opcodes internal header
With the changes done in previous patches, print_insn_XXX functions
don't have to be external visible out of opcodes, because both gdb
and objdump select disassemblers through a single interface.
This patch moves these print_insn_XXX declarations from
include/dis-asm.h to opcodes/disassemble.h, which is a new header
added by this patch.

/* Main entry point for printing operands.
|
|
|
|
|
XINFO is a `void *' and not a `disassemble_info *' to not put a requirement
|
|
|
|
|
of dis-asm.h on cgen.h.
|
|
|
|
|
|
|
|
|
|
This function is basically just a big switch statement. Earlier versions
|
|
|
|
|
used tables to look up the function to use, but
|
|
|
|
|
- if the table contains both assembler and disassembler functions then
|
|
|
|
|
the disassembler contains much of the assembler and vice-versa,
|
|
|
|
|
- there's a lot of inlining possibilities as things grow,
|
|
|
|
|
- using a switch statement avoids the function call overhead.
|
|
|
|
|
|
|
|
|
|
This function could be moved into `print_insn_normal', but keeping it
|
|
|
|
|
separate makes clear the interface between `print_insn_normal' and each of
|
|
|
|
|
the handlers. */
