Release file format: -------------------- The release files itest.sa and ftest.sa are essentially hexadecimal images of the actual tests. This format is the ONLY format that will be supported. The hex images were created by assembling the source code and then converting the resulting binary output images into ASCII text files. The hexadecimal numbers are listed using the Motorola Assembly syntax assembler directive "dc.l" (define constant longword). The files can be converted to other assembly syntaxes by using any word processor with a global search and replace function. To assist in assembling and linking these modules with other modules, the installer should add symbolic labels to the top of the files. This will allow the calling routines to access the entry points of these packages. The source code itest.s and ftest.s have been included but only for documentation purposes. Release file structure: ----------------------- (top of module) ----------------- | | - 128 byte-sized section (1) | Call-Out | - 4 bytes per entry (user fills these in) | | ----------------- | | - 8 bytes per entry (2) | Entry Point | - user does "bsr" or "jsr" to this address | | ----------------- | | - code section (3) ~ ~ | | ----------------- (bottom of module) The first section of this module is the "Call-out" section. This section is NOT INCLUDED in {i,f}test.sa (an example "Call-out" section is provided at the end of this file). The purpose of this section is to allow the test routines to reference external printing functions that must be provided by the host operating system. This section MUST be exactly 128 bytes in size. There are 32 fields, each 4 bytes in size. Each field corresponds to a function required by the test packages (these functions and their location are listed in "68060{ISP,FPSP}-TEST call-outs" below). Each field entry should contain the address of the corresponding function RELATIVE to the starting address of the "call-out" section. The "Call-out" section must sit adjacent to the {i,f}test.sa image in memory. Since itest.sa and ftest.sa are individual tests, they each require their own "Call-out" sections. The second section, the "Entry-point" section, is used by external routines to access the test routines. Since the {i,f}test.sa hex files contain no symbol names, this section contains function entry points that are fixed with respect to the top of the package. The currently defined entry-points are listed in section "68060{ISP,FPSP}-TEST entry points" below. A calling routine would simply execute a "bsr" or "jsr" that jumped to the selected function entry-point. For example, to run the 060ISP test, write a program that includes the itest.sa data and execute something similar to: bsr _060ISP_TEST+128+0 (_060ISP_TEST is the starting address of the "Call-out" section; the "Call-out" section is 128 bytes long; and the 68060ISP test entry point is located 0 bytes from the top of the "Entry-point" section.) The third section is the code section. After entering through an "Entry-point", the entry code jumps to the appropriate test code within the code section. 68060ISP-TEST Call-outs: ------------------------ 0x0: _print_string() 0x4: _print_number() 68060FPSP-TEST Call-outs: ------------------------- 0x0: _print_string() 0x4: _print_number() The test packages call _print_string() and _print_number() as subroutines and expect the main program to print a string or a number to a file or to the screen. In "C"-like fashion, the test program calls: print_string("Test passed"); or print_number(20); For _print_string(), the test programs pass a longword address of the string on the stack. For _print_number(), the test programs pass a longword number to be printed. For debugging purposes, after the main program performs a "print" for a test package, it should flush the output so that it's not buffered. In this way, if the test program crashes, at least the previous statements printed will be seen. 68060ISP-TEST Entry-points: --------------------------- 0x0: integer test 68060FPSP-TEST Entry-points: ---------------------------- 0x00: main fp test 0x08: FP unimplemented test 0x10: FP enabled snan/operr/ovfl/unfl/dz/inex The floating-point unit test has 3 entry points which will require 3 different calls to the package if each of the three following tests is desired: main fp test: tests (1) unimp effective address exception (2) unsupported data type exceptions (3) non-maskable overflow/underflow exceptions FP unimplemented: tests FP unimplemented exception. this one is separate from the previous tests for systems that don't want FP unimplemented instructions. FP enabled: tests enabled snan/operr/ovfl/unfl/dz/inex. basically, it enables each of these exceptions and forces each using an implemented FP instruction. this process exercises _fpsp_{snan,operr,ovfl,unfl,dz,inex}() and _real_{snan,operr,ovfl,unfl,dz,inex}(). the test expects _real_XXXX() to do nothing except clear the exception and "rte". if a system's _real_XXXX() handler creates an alternate result, the test will print "failed" but this is acceptable. Miscellaneous: -------------- Again, itest.sa and ftest.sa are simple tests and do not thoroughly test all 68060SP connections. For example, they do not test connections to _real_access(), _real_trace(), _real_trap(), etc. because these will be system-implemented several different ways and the test packages must remain system independent.
