ff69cd3f50 The __used__ change doesn't work on 2.95/vax. Put an #ifdef back in for vax and 
reverted it to __unused__ as it was before

950f51e55c Remove unused, -- just used is enough. From uwe. 2005-04-24 18:18:52 +00:00

d066f8aee0 Add a __used__ attribute next to the __unused__ attribute, because we don't 
want the optimizer to get rid of the whole code erroneously (which happens
with -O6 on sparc64).

1e627ed78e Make gmon / mcount work properly for threaded applications by keeping 
thread-specific gmonparam structures and then merging them before dumping
the profile buffers.

61a8612dd3 Use snprintf instead of hand crafted string copy and numeric conversion. 
Avoids problems if/when the pid is greater than 999999.

38c96853cf Last of the .Os cleanups. .Os is defined in the tmac.doc-common file, 
so we shouldn't override it with versions in the manpages.  Wheee!

6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename 
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

ef8dc9789a don't actually compile any code if building in a _STANDALONE environment 
(e.g. libkern for boot blocks), since profiling support doesn't make

a13d8bf828 use __inline and __asm, rather than inline and asm. By default (without -g) 
lint won't accept the latter two, but will accept the former two as valid.
As far as gcc's concerned, they're the same.

347a3b2582 Copy over from libkern:

0396d19a02 use p->hashfraction when doing non-time-critical calculations, rather than 
using HASHFRACTION directly.  in time-critical calculations, if HASHFRACTION
is a power of two, check that p->hashfraction == HASHFRACTION and if so do
the calculation with the compiled-in value so that the compiler can optimize
out (potentially) expensive divisions.  if p->hashfraction != HASHFRACTION,
actually do the division.  This has the result that on machines with slow
division, the division can be optimized out of the common case, but that
if HASHFRACTION changes from the compiled-in value (for whatever reason),
profiling will still work.  Changes suggested by Chris Torek.
