* elf/tls-macros.h [__ia64__] (TLS_IE, TLS_LD, TLS_GD): Add gp
register as input to asm.
+2003-04-01 Jakub Jelinek <jakub@redhat.com>
+
+ * pthread.c (__pthread_wait_for_restart_signal): Use
+ __pthread_sigsuspend instead of sigsuspend.
+ * internals.h (__pthread_sigsuspend): New prototype.
+ * Makefile (libpthread-routines): Add pt-sigsuspend.
+ (tests): Add tst-cancel7.
