simonb ecce47356a Disable malloc's hints to the kernel - now that the madvise() syscall
actually does something, this can be expensive.  From discussion on
current-users.

Note that the man page is already correct - we imported malloc.c from
FreeBSD before they made the same change but malloc.3 after...

enami d76da5f70c Fix the bug introduced in rev 1.28 and actually caused failure on alpha;
In the function malloc_make_chunks, don't define the local variable ``l'',
which is used to hold the actual size of pginfo, as size_t.  Define it as
a signed integer as before.  We expect it to become zero or negative value,
and we know that it is much smaller than pagesize and it is small enough to
fit in signed interger.

thorpej 62c7591543 Back out the previous 2 revs. The delint'ing of this file caused
something to break horribly on the Alpha.

kleink 9e00e84f98 Restore the behaviour of not setting errno to ENOMEM when allocating 0
units of storage and returning a null pointer in System V mode; this was
broken by the `fix' in rev. 1.24.  Also, as it is stated in ISO C that
such operation does not constitute an allocation failure, do not abort()
even if the `X' option is set.

Amusingly enough the SVID, Fourth Edition, specifies the `unique pointer'
return behaviour for this kind of allocation, so this is kind of mis-named.

tls e89d5d52c5 The 'new malloc' (phk's malloc, from FreeBSD) is now our only malloc. 1999-06-26 04:44:36 +00:00
kleink fd13be3c46 Protect access of state with a mutex. Miscellaneous notes:
* still needs an implementation-independent ("reentrant.h") method for
disabling cancellation,
* break a leg to leave realloc() `storage compaction' as was for non-reentrant
code,
* use of stdio in assertion code is unsafe.

jtc 43fa6fe319 If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore.  The library will use those
names internally.  Weak aliases are used to provide the original names
to the API.

This is only the first part of this change.  It is most of the functions
which are implemented in C for all NetBSD ports.  Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
