Update.
1999-12-09 Andreas Jaeger <aj@suse.de> * nis/nss_compat/compat-pwd.c (internal_getpwuid_r): Always set errno to ENOENT when returning NSS_STATUS_NOTFOUND. Reported by Christian Starkjohann <cs@obdev.at>. 1999-12-09 Andreas Jaeger <aj@suse.de> * sysdeps/i386/fpu/libm-test-ulps: Added some ulps. 1999-12-09 Jakub Jelinek <jakub@redhat.com> * stdlib/longlong.h: Update from latest egcs version. * sysdeps/sparc/fpu/fegetenv.c: Add semicolons. * sysdeps/unix/sysv/linux/bits/errno.h (__errno_location): __THROW has to preceede __attribute__, otherwise g++ barfs. * sysdeps/unix/sysv/linux/sparc/sys/ptrace.h: Make things compile on sparc64-*-linux. * sysdeps/unix/sysv/linux/sparc/sparc64/register-dump.h: Changed to use sigcontext. * sysdeps/unix/sysv/linux/sparc/sparc64/sigcontextinfo.h: Likewise. 1999-12-05 Wolfram Gloger <wg@malloc.de> * malloc/malloc.c (arena_get2): If generating a new arena fails, try to generate a minimal one and hope for mmap_chunk() to succeed later. 1999-11-07 Wolfram Gloger <wg@malloc.de> * malloc/thread-m.h [NO_THREADS]: The mutex_* macros now let mutex_t work as an `in-use' flag even without threads. * malloc/malloc.c (USE_ARENAS): New feature flag, controls support for multiple arenas separately from NO_THREADS.

1999-12-09 Jakub Jelinek <jakub@redhat.com>
|
||||
|

on sparc64-*-linux.

1999-12-05 Wolfram Gloger <wg@malloc.de>

try to generate a minimal one and hope for mmap_chunk() to succeed
|

later.
|
||||
|

1999-11-07 Wolfram Gloger <wg@malloc.de>
|

* malloc/thread-m.h [NO_THREADS]: The mutex_* macros now let

mutex_t work as an `in-use' flag even without threads.
|
||||
* malloc/malloc.c (USE_ARENAS): New feature flag, controls support
|

for multiple arenas separately from NO_THREADS.

(mALLOc, chunk_realloc, mEMALIGn, cALLOc) [USE_ARENAS]: try to
