When HPPA switched to NPTL, we +dropped the use of ldcw, and switched to the kernel helper routine for +compare-and-swap. This allowed HPPA to use the 4-word 16-byte aligned +lock words, and alignment words to store the additional pthread_cond_t +data.

In this case, the first +four words were set to one, and must be cleared before any NPTL code +used these words. + +We didn't want to use LDCW, because it continues to be a source of bugs +when applications memset pthread_cond_t to all zeroes by accident. This +works on all other architectures where lock words are unlocked at zero. +Remember that because of the semantics of LDCW, a locked word is set to +zero, and an unlocked word is set to 1. + +Instead we used atomic_compare_and_exchange_val_acq, but we couldn't use +this on any of the pthread_cond_t words, otherwise it might interfere +with the current operation of the structure.

The first thread to come upon a +pthread_cond_t with a 1 in the __initializer field, will +compare-and-swap the value, placing a 2 there which will cause all other +threads using the same pthread_cond_t to wait for the completion of the +initialization. Lastly, we use a store (with memory barrier) to change +__initializer from 2 to 0. Note that the store is strongly ordered, but +we use the PA 1.1 compatible form which is ",ma" with zero offset. + +In the future, when the application is recompiled with NPTL +PTHREAD_COND_INITIALIZER it will be a quick compare-and-swap, which +fails because __initializer is zero, and the structure will be used as +is correctly. */ + +#define cond_compat_clear(var) \ +({ \ + int tmp = 0; \ + var->__data.__lock = 0; \ + var->__data.__futex = 0; \ + var->__data.__mutex = NULL; \ + /* Clear __initializer last, to indicate initialization is done. */ \ + __asm__ __volatile__ ("stw,ma %1,0(%0)" \ + : : "r" (&var->__data.__initializer), "r" (tmp) : "memory"); \ +}) + +#define cond_compat_check_and_clear(var) \ +({ \ + int ret; \ + volatile int *value = &var->__data.__initializer; \ + if ((ret = atomic_compare_and_exchange_val_acq(value, 2, 1))) \ + { \ + if (ret == 1) \ + { \ + /* Initialize structure. */ \ + cond_compat_clear (var); \ + } \ + else \ + { \ + /* Yield until structure is initialized. */ \ + while (*value == 2) sched_yield (); \ + } \ + } \ +}) + +#endif diff --git a/sysdeps/unix/sysv/linux/hppa/kernel-features.h b/sysdeps/unix/sysv/linux/hppa/kernel-features.h new file mode 100644 index 0000000000..e869c14bdd --- /dev/null +++ b/sysdeps/unix/sysv/linux/hppa/kernel-features.h @@ -0,0 +1,44 @@ +/* Set flags signalling availability of kernel features based on given + kernel version number. + Copyright (C) 2006-2014 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
