From d4f64e1ad7d7836fbd9b01f9c5d410db930c38ce Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 10 Mar 2003 08:50:36 +0000 Subject: 2003-03-10 Roland McGrath * allocatestack.c (allocate_stack) [!TLS_MULTIPLE_THREADS_IN_TCB]: Instead of setting PD->multiple_threads, set globals __pthread_multiple_threads and __libc_multiple_threads. * sysdeps/pthread/createthread.c (create_thread): Likewise. * sysdeps/i386/tls.h (TLS_MULTIPLE_THREADS_IN_TCB): Define it. * sysdeps/s390/tls.h (TLS_MULTIPLE_THREADS_IN_TCB): Likewise. * descr.h (struct pthread): Conditionalize first member on [!TLS_DTV_AT_TP]. Replace the `header' member with an anonymous union containing an anonymous tcbhead_t. Move `list' member out. [TLS_MULTIPLE_THREADS_IN_TCB]: Define a `multiple_threads' member. * allocatestack.c: Remove use of `header.data.' prefix. * pthread_create.c: Likewise. * init.c (__pthread_initialize_minimal_internal): Likewise. * sysdeps/pthread/createthread.c (create_thread): Likewise. * sysdeps/i386/tls.h (INSTALL_DTV): Add parens. (THREAD_SELF, THREAD_DTV, INSTALL_NEW_DTV): No `header.data.' prefix. * sysdeps/x86_64/tls.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep-cancel.h (SINGLE_THREAD_P): Likewise. * sysdeps/unix/sysv/linux/sh/sysdep-cancel.h (SINGLE_THREAD_P): Likewise. * sysdeps/i386/tls.h (tcbhead_t): Remove `list' member. * sysdeps/s390/tls.h (tcbhead_t): Likewise. --- nptl/sysdeps/i386/tls.h | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) (limited to 'nptl/sysdeps/i386') diff --git a/nptl/sysdeps/i386/tls.h b/nptl/sysdeps/i386/tls.h index 9c4c481ccb..5b70586f27 100644 --- a/nptl/sysdeps/i386/tls.h +++ b/nptl/sysdeps/i386/tls.h @@ -44,9 +44,10 @@ typedef struct void *self; /* Pointer to the thread descriptor. */ int multiple_threads; uintptr_t sysinfo; - list_t list; } tcbhead_t; +# define TLS_MULTIPLE_THREADS_IN_TCB 1 + #else /* __ASSEMBLER__ */ # include #endif @@ -116,12 +117,12 @@ union user_desc_init /* Install the dtv pointer.
