/* HOW TO COMPILE:

* 32bit build:
   gcc -Winline -Wall -g -O -mregnames -maltivec
* 64bit build:
   gcc -Winline -Wall -g -O -mregnames -maltivec -m64

This program is useful, but the register usage conventions in
it are a complete dog.  In particular, _patch_op_imm has to
be inlined, else you wind up with it segfaulting in
completely different places due to corruption (of r20 in the
case I chased).

/*
 * Theory of operations:
 * a few registers are reserved for the test program:
 * r14 => r18
 * f14 => f18
 * I do preload test values in r14 thru r17 (or less, depending on the number
 * of register operands needed), patch the test opcode if any immediate
 * operands are required, execute the tested opcode.
 * XER, CCR and FPSCR are cleared before every test.
 * I always get the result in r17 and also save XER and CCR for fixed-point
 * operations. I also check FPSCR for floating points operations.
 *
 * Improvments:
 * a more clever FPSCR management is needed: for now, I always test
 * the round-to-zero case. Other rounding modes also need to be tested.
 */

/*
 * Operation details
 * -----------------
 * The 'test' functions (via all_tests[]) are wrappers of single asm instns
 *
 * The 'loops' (e.g. int_loops) do the actual work:
 *  - loops over as many arguments as the instn needs (regs | imms)
 *     - sets up the environment (reset cr,xer, assign src regs...)
 *     - maybe modifies the asm instn to test different imm args
 *     - calls the test function
 *     - retrieves relevant register data (rD,cr,xer,...)
 *     - prints argument and result data.
 *
 * More specifically...
 *
 * all_tests[i] holds insn tests
 *  - of which each holds: {instn_test_arr[], description, flags}
 *
 * flags hold 3 instn classifiers: {family, type, arg_type}
 *
 * // The main test loop:
 * do_tests( user_ctl_flags ) {
 *    foreach(curr_test = all_test[i]) {
 *
 *       // flags are used to control what tests are run:
 *       if (curr_test->flags && !user_ctl_flags)
 *          continue;
 *
 *       // a 'loop_family_arr' is chosen based on the 'family' flag...
 *       switch(curr_test->flags->family) {
 *       case x: loop_family_arr = int_loops;
 *      ...
 *       }
 *
 *       // ...and the actual test_loop to run is found by indexing into
 *       // the loop_family_arr with the 'arg_type' flag:
 *       test_loop = loop_family[curr_test->flags->arg_type]
 *
 *       // finally, loop over all instn tests for this test:
 *       foreach (instn_test = curr_test->instn_test_arr[i]) {
 *
 *          // and call the test_loop with the current instn_test function,name
 *          test_loop( instn_test->func, instn_test->name )
 *       }
 *    }
 * }
 *
 *
 * Details of intruction patching for immediate operands
 * -----------------------------------------------------
 * All the immediate insn test functions are of the form {imm_insn, blr}
 * In order to patch one of these functions, we simply copy both insns
 * to a stack buffer, and rewrite the immediate part of imm_insn.
 * We then execute our stack buffer.
 * All ppc instructions are 32bits wide, which makes this fairly easy.
 *
 * Example:
 * extern void test_addi (void);
 * asm(".section \".text\"\n"
 *     "    .align 2\n"
 *     "    .type test_addi,@function\n"
 *     "test_addi:\n"
 *     "    addi\n"
 *     "    blr\n"
 *     "    .previous\n"
 *     );
 *
 * We are interested only in:
 *      "    addi         17, 14, 0\n"
 *      "    blr\n"
 *
 * In a loop test, we may see:
 * uint32_t func_buf[2];               // our new stack based 'function'
 * for imm...                          // loop over imm
 *   init_function( &func, func_buf );   // copy insns, set func ptr
 *   patch_op_imm16(&func_buf[0], imm);  // patch 'addi' insn
 *   ...
 *   (*func)();                              // exec our rewritten code
 *
 * patch_op_imm16() itself simply takes the uint32_t insn and overwrites
 * the immediate field with the new value (which, for 'addi', is the
 * low 16 bits).
 *
 * So in the loop test, if 'imm' is currently 9, and p[0] is:
 *   0x3A2E0000   => addi 17, 14, 0
 *
 * after patch_op_imm16(), func_buf[0] becomes:
 *   0x3A2E0009   => addi 17, 14, 9
 *
 * Note: init_function() needs to be called on every iteration
 *  - don't ask me why!
