Re: [9fans] Non-stack-based calling conventions

[maht <mattmobile@proweb.co.uk>]

I'll preceed my invective with something relevant :

Forth's calling convention means the stack is used less for nested calls.

For the C version there's all sorts of pushing and popping return
addresses and arguments on to the stack

float
sqr(x float)
{
    return x * x;
}

float
hyp(x float, y float)
{
    return sqrt(sqr(x) + sqr(y));
}

Whereas in the Forth version, the only thing that gets pushed and popped
is the address of the next function, the arguments are on the stack
already (assume the FP versions of the Words are used) :

:sqr dup *
:hyp sqr over sqr + sqrt


Now on with the invective



lolz, I go away for 3 days and I must have left the back door open
because when I came back the place was full of ignorant bitches.

I like both of these :

grep impressive /sys/games/lib/fortune

I'm glad that the "problem" of Plan 9 has been solved at last, it's the
people who have been using it for n years.

My personal n started on June 7 2000, I guess that day is akin to "the
September that Never Ended" to those for whom n > 7.
