From 518b53086ca3c10b3587e1162602c8f2aacccbde Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 4 Mar 2003 20:55:08 +0000 Subject: Update. * pthread_create.c: Define __pthread_keys using nocommon attribute, not by placing it explicitly in bss. Remove DEFINE_DEALLOC definition. Not needed anymore. * allocatestack.c: Define ARCH_MAP_FLAGS if not already defined. Use it in mmap call to allocate stacks. * sysdeps/pthread/createthread.c (create_thread): Fix comment. --- nptl/ChangeLog | 9 +++++++++ nptl/allocatestack.c | 8 +++++++- nptl/pthread_create.c | 3 +-- 3 files changed, 17 insertions(+), 3 deletions(-) (limited to 'nptl') diff --git a/nptl/ChangeLog b/nptl/ChangeLog index 92183629aa..8756489cad 100644 --- a/nptl/ChangeLog +++ b/nptl/ChangeLog @@ -1,5 +1,14 @@ 2003-03-04 Ulrich Drepper + * pthread_create.c: Define __pthread_keys using nocommon + attribute, not by placing it explicitly in bss. + Remove DEFINE_DEALLOC definition.
