nptl: Change tst-typesizes to _Static_assert
Instead of rely on runtime check to assure correct pthread types size a better strategy would use _Static_assert to trigger an error on build time (and thus allowing to check to potentially ABI breakage on cross-compiling make check). This patch moves nptl/tst-typesizes.c to libpthread build time on each specific initialization routine and also remove some runtime redundant asserts for the same type sizes. Checked on x86_64-linux-gnu and with a build check for all affected ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf, hppa-linux-gnu, i686-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu, mips64-linux-gnu, mips64-n32-linux-gnu, mips-linux-gnu, powerpc64le-linux-gnu, powerpc-linux-gnu, s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, tilegx-linux-gnu, tilegx-linux-gnu-x32, tilepro-linux-gnu, x86_64-linux-gnu, and x86_64-linux-x32). * nptl/pthreadP.h (ASSERT_TYPE_SIZE, ASSERT_PTHREAD_INTERNAL_SIZE): New macros. * nptl/pthread_attr_init.c (__pthread_mutex_init): Add build time checks for expected input type size. * nptl/pthread_barrier_init.c (__pthread_barrier_init): Likewise. * nptl/pthread_barrierattr_init.c (pthread_barrierattr_init): Likewise. * nptl/pthread_cond_init.c (__pthread_cond_init): Likewise. * nptl/pthread_condattr_init.c (__pthread_condattr_init): Likewise. * nptl/pthread_mutex_init.c (__pthread_mutex_init): Likewise. * nptl/pthread_mutexattr_init.c (__pthread_mutexattr_init): Likewise. * nptl/pthread_rwlock_init.c (__pthread_rwlock_init): Likewise. * nptl/pthread_rwlockattr_init.c (pthread_rwlockattr_init): Likewise. * nptl/sem_init.c (__new_sem_init, __old_sem_init): Likewise * nptl/pthread_attr_destroy.c (__pthread_attr_destroy): Remove superflous runtime assert check. * nptl/pthread_attr_getaffinity.c (__pthread_attr_getaffinity_new): Likewise. * nptl/pthread_attr_getdetachstate.c (__pthread_attr_getdetachstate): Likewise. * nptl/pthread_attr_getguardsize.c (pthread_attr_getguardsize): Likewise. * nptl/pthread_attr_getinheritsched.c (__pthread_attr_getinheritsched): Likewise. * nptl/pthread_attr_getschedparam.c (__pthread_attr_getschedparam): Likewise. * nptl/pthread_attr_getschedpolicy.c (__pthread_attr_getschedpolicy): Likewise. * nptl/pthread_attr_getscope.c (__pthread_attr_getscope): Likewise. * nptl/pthread_attr_getstack.c (__pthread_attr_getstack): Likewise. * nptl/pthread_attr_getstackaddr.c (__pthread_attr_getstackaddr): Likewise. * nptl/pthread_attr_getstacksize.c (__pthread_attr_getstacksize): Likewise. * nptl/pthread_attr_setaffinity.c (__pthread_attr_setaffinity_new): Likewise. * nptl/pthread_attr_setdetachstate.c (__pthread_attr_setdetachstate): Likewise. * nptl/pthread_attr_setguardsize.c (pthread_attr_setguardsize): Likewise. * nptl/pthread_attr_setinheritsched.c (__pthread_attr_setinheritsched): Likewise. * nptl/pthread_attr_setschedparam.c (__pthread_attr_setschedparam): Likewise. * nptl/pthread_attr_setschedpolicy.c (__pthread_attr_setschedpolicy): Likewise. * nptl/pthread_attr_setscope.c (__pthread_attr_setscope): Likewise. * nptl/pthread_attr_setstack.c (__pthread_attr_setstack, __old_pthread_attr_setstack): Likewise. * nptl/pthread_attr_setstackaddr.c (__pthread_attr_setstackaddr): Likewise. * nptl/pthread_attr_setstacksize.c (__pthread_attr_setstacksize): Likewise. * nptl/pthread_getattr_default_np.c (pthread_getattr_default_np): Likewise. * nptl/pthread_mutex_lock.c (__pthread_mutex_lock): Likewise. * nptl/pthread_setattr_default_np.c (pthread_setattr_default_np): Likewise. * nptl/tst-typesizes.c: Remove file.
