The multiplication of 525252525252 * 2 produces 777777777776,652525252524, which is correct for the PDP-10's 72-bit "dual sign"
|
||||||
|
format. However, the first time I ran this test, it failed -- not because the result was wrong, but because the value calculated
|
||||||
|
for the expected result was wrong.
|
||||||
|
|
||||||
|
The source code for the test produces the expected results by performing 36-bit multiplication in the MACRO-10 Assembler:
|
||||||
|
|
||||||
|
775 ;MULTIPLY A FLOATING 1 BY 1010...101010
|
||||||
|
776 525252 525252 V1=N1
|
||||||
|
777 652525 252524 V2=N1*XX
|
||||||
|
|
||||||
|
but the expected result *my* MACRO-10 Mini-Assembler calculated was different:
|
||||||
|
|
||||||
|
>> dw 44442 l1
|
||||||
|
044442: 252525 252524
|
||||||
|
|
||||||
|
My result wasn't really the *wrong value*; it was the correct (albeit truncated) value in the *wrong format*. My expression
|
||||||
|
parser was performing simple JavaScript multiplication and then truncating the result to 36 bits; MACRO-10 performs a similar
|
||||||
|
calculation, but it also adjusts the sign of the low 36 bits to match the sign of the high 36 bits -- because that's what the
|
||||||
|
PDP-10 does, too.
|
||||||
|
|
||||||
|
My solution was to move the expression parser's *multiplication* code to its own function, *evalMUL()*, and then change
|
||||||
|
the PDP-10 Debugger to override *evalMUL()* with its own function that calls the PDP-10 CPU *doMUL()* function, guaranteeing
|
||||||
|
that all multiplication results are performed with the same 72-bit precision and returned in the same PDP-10 72-bit format
|
||||||
|
(before being truncated to 36 bits).
|
||||||
|
|
||||||
|
Unfortunately, this creates an incestuous relationship between CPU functionality being tested and the code testing it,
|
||||||
|
because it increases the likelihood that the multiplication tests will succeed even if/when they calculate incorrect results,
|
||||||
|
at least whenever the expected results are being calculated with the same multiplicands that the test itself uses.
|
||||||
|
|
||||||
|
So, as a precaution, I added some *DEBUG* code to the *evalMUL()* function that outputs all the instances where JavaScript
|
||||||
|
multiplication and PDP-10 multiplication differ, so that I can verify that all my PDP-10 results match those in DEC's
|
||||||
|
[MACRO-10 Listing](DAKAL.LST.txt), which I'm treating as "the gold standard."
