Fix the logic operation for atomic_nand_{8,16,32,64}
...
From the gcc docs the operations are as follows
{ tmp = *ptr; *ptr = ~(tmp & value); return tmp; } // nand
{ tmp = ~(*ptr & value); *ptr = tmp; return *ptr; } // nand
yes, this is really rather strange.

- Remove memory barriers from the atomic ops. I don't understand why those
are there. Is it some architectural thing, or for a CPU bug, or just
over-caution maybe? They're not needed for correctness.
- Have unlikely conditional branches go forwards to help the static branch
predictor.

2020-06-06 22:23:31 +00:00

Improvements to the problib(3) API:
...
==> Provide a much more complete set of setters and getters for different
value types in the prop_array_util(3) and prop_dictionary_util(3)
functions.
==> Overhaul the prop_data(3), prop_number(3), and prop_string(3) APIs
to be easier to use and less awkwardly named, Deprecate the old
awkward names, and produce link-time warnings when they are referenced.
==> Deprecate mutable prop_data(3) and prop_string(3) objects. The old
APIs that support them still exist, but will now produce link-time
warnings when used.
==> When the new prop_string(3) API is used, strings are internally
de-duplicated as a memory footprint optimization.
==> Provide a rich set of bounds-checked gettter functions in and a
corresponding set of convenience setters in the prop_number(3) API.
==> Add a new prop_bool_value(3) function that is equivalent to
prop_bool_true(3), but aligned with the new "value" routines in
prop_data(3), prop_string(3), and prop_number(3).

Add m68k assembler version of __muldi3().
...
This is intended for 68060:
- GCC does not emit __muldi3() for 68020-40, that have 32 * 32 --> 64 mulul
- mulsl (and moveml), used in this code, are not implemented for 68010
In comparison with that from compiler_rt, this version saves:
- 12% of processing time
- 12 bytes of stack
- 50 bytes of code size
Also, slightly faster, memory saving, and smaller than libgcc version.
By examining with evcnt(9), __muldi3() is invoked more than 1000 times per
sec by kernel, which should justify to introduce assembler version of this
function.
