This format is the 39ONLY format that will be supported. The hex images were created 40by assembling the source code and then converting the resulting 41binary output images into ASCII text files. The hexadecimal 42numbers are listed using the Motorola Assembly syntax assembler 43directive "dc.l" (define constant longword). The files can be 44converted to other assembly syntaxes by using any word processor 45with a global search and replace function. 46 47To assist in assembling and linking these modules with other modules, 48the installer should add symbolic labels to the top of the files. 49This will allow the calling routines to access the entry points 50of these packages. 51 52The source code itest.s and ftest.s have been included but only 53for documentation purposes. 54 55Release file structure: 56----------------------- 57 58(top of module) 59 ----------------- 60 | | - 128 byte-sized section 61 (1) | Call-Out | - 4 bytes per entry (user fills these in) 62 | | 63 ----------------- 64 | | - 8 bytes per entry 65 (2) | Entry Point | - user does "bsr" or "jsr" to this address 66 | | 67 ----------------- 68 | | - code section 69 (3) ~ ~ 70 | | 71 ----------------- 72(bottom of module) 73 74The first section of this module is the "Call-out" section. This section 75is NOT INCLUDED in {i,f}test.sa (an example "Call-out" section is provided at 76the end of this file). The purpose of this section is to allow the test 77routines to reference external printing functions that must be provided 78by the host operating system. This section MUST be exactly 128 bytes in 79size. There are 32 fields, each 4 bytes in size. Each field corresponds 80to a function required by the test packages (these functions and their 81location are listed in "68060{ISP,FPSP}-TEST call-outs" below). Each field 82entry should contain the address of the corresponding function RELATIVE to 83the starting address of the "call-out" section. The "Call-out" section must 84sit adjacent to the {i,f}test.sa image in memory. Since itest.sa and ftest.sa 85are individual tests, they each require their own "Call-out" sections. 86 87The second section, the "Entry-point" section, is used by external routines 88to access the test routines. Since the {i,f}test.sa hex files contain 89no symbol names, this section contains function entry points that are fixed 90with respect to the top of the package. The currently defined entry-points 91are listed in section "68060{ISP,FPSP}-TEST entry points" below. A calling 92routine would simply execute a "bsr" or "jsr" that jumped to the selected 93function entry-point. 94 95For example, to run the 060ISP test, write a program that includes the 96itest.sa data and execute something similar to: 97 98 bsr _060ISP_TEST+128+0 99 100(_060ISP_TEST is the starting address of the "Call-out" section; the "Call-out" 101section is 128 bytes long; and the 68060ISP test entry point is located 1020 bytes from the top of the "Entry-point" section.) 103 104The third section is the code section. After entering through an "Entry-point", 105the entry code jumps to the appropriate test code within the code section. 106 10768060ISP-TEST Call-outs: 108------------------------ 1090x0: _print_string() 1100x4: _print_number() 111 11268060FPSP-TEST Call-outs: 113------------------------- 1140x0: _print_string() 1150x4: _print_number() 116 117The test packages call _print_string() and _print_number() 118as subroutines and expect the main program to print a string 119or a number to a file or to the screen. 120In "C"-like fashion, the test program calls: 121 122 print_string("Test passed"); 123 124 or 125 126 print_number(20); 127 128For _print_string(), the test programs pass a longword address 129of the string on the stack. For _print_number(), the test programs pass 130a longword number to be printed. 131 132For debugging purposes, after the main program performs a "print" 133for a test package, it should flush the output so that it's not 134buffered. In this way, if the test program crashes, at least the previous 135statements printed will be seen. 136 13768060ISP-TEST Entry-points: 138--------------------------- 1390x0: integer test 140 14168060FPSP-TEST Entry-points: 142---------------------------- 1430x00: main fp test 1440x08: FP unimplemented test 1450x10: FP enabled snan/operr/ovfl/unfl/dz/inex 146 147The floating-point unit test has 3 entry points which will require 1483 different calls to the package if each of the three following tests 149is desired: 150 151main fp test: tests (1) unimp effective address exception 152 (2) unsupported data type exceptions 153 (3) non-maskable overflow/underflow exceptions 154 155FP unimplemented: tests FP unimplemented exception. this one is 156 separate from the previous tests for systems that don't 157 want FP unimplemented instructions. 158 159FP enabled: tests enabled snan/operr/ovfl/unfl/dz/inex. 160 basically, it enables each of these exceptions and forces 161 each using an implemented FP instruction. this process 162 exercises _fpsp_{snan,operr,ovfl,unfl,dz,inex}() and 163 _real_{snan,operr,ovfl,unfl,dz,inex}(). the test expects 164 _real_XXXX() to do nothing except clear the exception 165 and "rte". if a system's _real_XXXX() handler creates an 166 alternate result, the test will print "failed" but this 167 is acceptable. 168 169Miscellaneous: 170-------------- 171Again, itest.sa and ftest.sa are simple tests and do not thoroughly 172test all 68060SP connections. For example, they do not test connections 173to _real_access(), _real_trace(), _real_trap(), etc. because these 174will be system-implemented several different ways and the test packages 175must remain system independent. 176 177Example test package set-up: 178---------------------------- 179_print_str: 180 . # provided by system 181 rts 182 183_print_num: 184 . # provided by system 185 rts 186 187 . 188 . 189 bsr _060FPSP_TEST+128+0 190 . 191 . 192 rts 193 194# beginning of "Call-out" section; provided by integrator. 195# MUST be 128 bytes long. 196_060FPSP_TEST: 197 long _print_str - _060FPSP_TEST 198 long _print_num - _060FPSP_TEST 199 space 120 200 201# ftest.sa starts here; start of "Entry-point" section. 202 long 0x60ff0000, 0x00002346 203 long 0x60ff0000, 0x00018766 204 long 0x60ff0000, 0x00023338 205 long 0x24377299, 0xab2643ea 206 . 207 . 208 . 209
