the expensive checks are skipped when (!DEBUG&&!PMAPCHECK) and all of the
light-weigth checks are skipped when (!DIAGNOSTIC&&!DEBUG&&!PMAPCHECK).
This bring pmap.o's text down from 21KB (with PMAPCHECK) to 18.5KB (DEBUG)
to 16KB text (!DIAGNOSTIC).
It is infeasible for some ARM ports to use anything but ELF/new-toolchain,
and this allows for the ARM ports that aren't ready for ELF to stay at
MACHINE_ARCH == arm32 until they're ready. The rest of the ARM ports
have a userbase such that if a flag day happens with the compiler (there
are a couple of ABI issues still being discussed), that it won't matter
so much.
Discussed with Ben Harris, Matt Thomas, and Chris Gilbert.
a refCount of 1 to indicate its presence on sufflist. Hence suffixes were
being removed by Suff_EndTransform() and being freed before all the
referential links were removed. This resulted in a malloc warning on 1.5.x:
make in free(): warning: chunk is already free.
This could be reproduced with the following simple Makefile passed to
"make -r":
=====
.SUFFIXES: .l .c
.l.c:
foo:
* Provide some GNUisms as extensions.
* Provide dynamically growable string space.
* Make define(defn(foo)) work correctly for builtins.
(The current version is supposed to be capable of satisfying autoconf.)
All still relevant NetBSD changes have been preserved in this version, and
formatting and style fixes have been applied in various places.
Thanks to Masao Uebayashi <uebayasi@soum.co.jp> for pointing this out.
the Branch Target Buffer of the BPRD bit changes.
* Enable Branch Prediction on the XScale by default.
* Don't invalidate the Branch Target Buffer explicitly. the i80200
manual (section 5.1, Branch Target Buffer Operation) notes that
manual software management of the BTB is unnecessary; it is flushed
implicitly when:
* processor resets
* FCSE process ID is written
* I-cache is invalidated
* sa110_cache_purgeD() is the same as sa110_cache_cleanD() on the
SA-1 -- make it an alias.
* sa110_cache_syncI() and sa110_cache_purgeID() are identical to
sa110_cache_cleanD() on the SA-1, with the exception that the
I-cache must also be flushed. Save code duplication by moving
the I-cache flush before the D-cache clean and letting it fall
through.
