From a0386a0da3369e271bbfc03d54c49ba4ab62cd3a Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 28 Sep 2000 23:32:48 +0000 Subject: Update. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 2000-09-28 Franz Sirl * sysdeps/unix/sysv/linux/kernel-features.h: Add __ASSUME_IPC64, only define it for powerpc for kernel >= 2.4.0. * sysdeps/unix/sysv/linux/msgctl.c: Test for __ASSUME_IPC64, not __ASSUME_32BITUIDS. * sysdeps/unix/sysv/linux/semctl.c: Likewise. * sysdeps/unix/sysv/linux/shmctl.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/ipc.h: Sync with kernel. * sysdeps/unix/sysv/linux/powerpc/bits/msq.h: New file. * sysdeps/unix/sysv/linux/powerpc/bits/sem.h: New file. * sysdeps/unix/sysv/linux/powerpc/bits/shm.h: New file. 2000-09-28 Martin Schwidefsksy * sysdeps/s390/atomicity.h: Fix compare_and_swap. * sysdeps/unix/sysv/linux/s390/bits/fcntl.h (F_GETLK64,F_SETLK64,F_SETLKW64): Use values from 2.4.0-test8. 2000-09-28 Denis Joseph Barrow * sysdeps/unix/sysv/linux/s390/sys/procfs.h: Use definitions from ucontext.h. * sysdeps/unix/sysv/linux/s390/sys/ucontext.h: Fix ucontext structure. 2000-09-27 Andreas Schwab * math/Makefile (distribute): Explicitly add the long double test sources, to get them included even if long double is not supported. 2000-09-27 Jes Sorensen * elf/soinit.c (struct object): Move definition to gccframe.h and include it. Problem identified by HJ Lu. * sysdeps/ia64/gccframe.h: New file. ia64 specific version of struct object to be searched for frame unwind info. * sysdeps/generic/gccframe.h: New file. Generic version of struct object to be searched for frame unwind info. 2000-09-28 Ulrich Drepper * manual/errno.texi: Correct error text for ENXIO. Reported by Jörg Schilling . 2000-09-27 Jes Sorensen * sysdeps/ia64/fpu/fsetexcptflg.c (fesetexceptflag): Set the exception status bits rather than the exception disable bits. Don't include math.h. * sysdeps/ia64/fpu/fgetexcptflg.c (fegetexceptflag): Report the status of exceptions currently raised rather than which exceptions are enabled. * sysdeps/ia64/fpu/fclrexcpt.c (feclearexcept): Typecase to fenv_t rather than unsigned long int. * sysdeps/ia64/fpu/fedisblxcpt.c (fedisableexcept): Only disable the exceptions actually requested by the caller and not just disable all exceptions. * sysdeps/ia64/fpu/feenablxcpt.c (feenableexcept): Exceptions on the ia64 are enabled by clearing the respective bits in the fpsr, not setting them. * sysdeps/ia64/bits/fenv.h: typedef fexcept_t and fenv_t to unsigned long int rather than unsigned long to be consistent with the coding conventions. 2000-09-20 H.J. Lu * sysdeps/ia64/fpu/fesetenv.c (fesetenv): Use fenv_t instead of unsigned long int. * sysdeps/ia64/fpu/fesetround.c (fesetround): Likewise. 2000-09-28 Ulrich Drepper * string/bits/string2.h: Unify #if usage. 2000-09-27 Jakub Jelinek * math/test-fenv.c (feexcp_mask_test): If enabling all exceptions and disabling underflow or overflow, disable inexact as well. * sysdeps/gnu/netinet/tcp.h: Add tcp_info defines and types. --- linuxthreads/sysdeps/s390/pt-machine.h | 29 +++++++++++++++++++++++++---- 1 file changed, 25 insertions(+), 4 deletions(-) (limited to 'linuxthreads/sysdeps') diff --git a/linuxthreads/sysdeps/s390/pt-machine.h b/linuxthreads/sysdeps/s390/pt-machine.h index 8de4a1a7c4..a006efc20c 100644 --- a/linuxthreads/sysdeps/s390/pt-machine.h +++ b/linuxthreads/sysdeps/s390/pt-machine.h @@ -30,12 +30,13 @@ testandset (int *spinlock) int ret; __asm__ __volatile__( + " la 1,%1\n" " lhi 0,1\n" " l %0,%1\n" - "0: cs %0,0,%1\n" + "0: cs %0,0,0(1)\n" " jl 0b" : "=&d" (ret), "+m" (*spinlock) - : : "0", "cc"); + : : "0", "1", "cc"); return ret; } @@ -46,6 +47,25 @@ testandset (int *spinlock) #define CURRENT_STACK_FRAME stack_pointer register char * stack_pointer __asm__ ("15"); +/* Return the thread descriptor for the current thread. + S/390 registers uses access register 0 as "thread register". */ +#define THREAD_SELF ({ \ + register pthread_descr __self; \ + __asm__ ("ear %0,%%a0" : "=d" (__self) ); \ + __self; \ +}) + +/* Initialize the thread-unique value. */ +#define INIT_THREAD_SELF(descr, nr) ({ \ + __asm__ ("sar %%a0,%0" : : "d" (descr) ); \ +}) + +/* Access to data in the thread descriptor is easy. */ +#define THREAD_GETMEM(descr, member) THREAD_SELF->member +#define THREAD_GETMEM_NC(descr, member) THREAD_SELF->member +#define THREAD_SETMEM(descr, member, value) THREAD_SELF->member = (value) +#define THREAD_SETMEM_NC(descr, member, value) THREAD_SELF->member = (value) + /* Compare-and-swap for semaphores. */ @@ -57,14 +77,15 @@ __compare_and_swap(long int *p, long int oldval, long int newval) int retval; __asm__ __volatile__( + " la 1,%1\n" " lr 0,%2\n" - " cs 0,%3,%1\n" + " cs 0,%3,0(1)\n" " ipm %0\n" " srl %0,28\n" "0:" : "=&d" (retval), "+m" (*p) : "d" (oldval) , "d" (newval) - : "cc", "0"); + : "cc", "0", "1" ); return retval == 0; } -- cgit 1.4.1
