/* This is a source file with infra-structure to test generators for
   assemblers and disassemblers.
 
   The strategy to generate testcases is as follows.  We'll output to
   two streams: one will get the assembly source, and the other will
   get regexps that match the expected binary patterns.
 
   To generate each instruction, the functions of a func[] are called,
   each with the corresponding func_arg.  Each function should set
   members of insn_data, to decide what it's going to output to the
   assembly source, the corresponding output for the disassembler
   tester, and the bits to be set in the instruction word.  The
   strings to be output must have been allocated with strdup() or
   malloc(), so that they can be freed.  A function may also modify
   insn_size.  More details in test-gen.c
 
   Because this would have generated too many tests, we have chosen to
   define ``random'' sequences of numbers/registers, and simply
   generate each instruction a couple of times, which should get us
   enough coverage.
 
   In general, test generators should be compiled/run as follows:
 
   % gcc test.c -o test
   % ./test > test.s 2 > test.d
 
   Please note that this file contains a couple of GCC-isms, such as
   macro varargs (also available in C99, but with a difference syntax)
   and labeled elements in initializers (so that insn definitions are
   simpler and safer).
 
   It is assumed that the test generator #includes this file after
   defining any of the preprocessor macros documented below.  The test
   generator is supposed to define instructions, at least one group of
   instructions, optionally, a sequence of groups.
 
   It should also define a main() function that outputs the initial
   lines of the assembler input and of the test control file, that
   also contains the disassembler output.  The main() funcion may
   optionally set skip_list too, before calling output_groups() or
   output_insns().  */
