From: Andi Kleen <ak@odo.jf.intel.com> With the recent tuning the C version of rwlocks is basically the same performance as the x86 assembler version for uncontended locks (with a a few cycles near the run-to-run variability). For others it should not matter anyways. So remove the assembler code and use the C version like other architectures. nptl/: 2014-05-06 Andi Kleen <ak@linux.intel.com> * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_rdlock.S: Remove. * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedrdlock.S: dito. * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedwrlock.S: dito. * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_unlock.S: dito. * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_wrlock.S: dito. * sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_rdlock.S: dito. * sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_timedrdlock.S: dito. * sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_timedwrlock.S: dito. * sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_unlock.S: dito. * sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_wrlock.S: dito. * sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_rdlock.S: dito. * sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_timedrdlock.S: dito. * sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_timedwrlock.S: dito. * sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_unlock.S: dito. * sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_wrlock.S: dito. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_rdlock.S: dito. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedrdlock.S: dito. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedwrlock.S: dito. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_unlock.S: dito. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_wrlock.S: dito. --- .../sysv/linux/i386/i486/pthread_rwlock_rdlock.S | 192 --------------- .../linux/i386/i486/pthread_rwlock_timedrdlock.S | 243 ------------------ .../linux/i386/i486/pthread_rwlock_timedwrlock.S | 236 ------------------ .../sysv/linux/i386/i486/pthread_rwlock_unlock.S | 151 ------------ .../sysv/linux/i386/i486/pthread_rwlock_wrlock.S | 183 -------------- .../sysv/linux/i386/i586/pthread_rwlock_rdlock.S | 19 -- .../linux/i386/i586/pthread_rwlock_timedrdlock.S | 19 -- .../linux/i386/i586/pthread_rwlock_timedwrlock.S | 19 -- .../sysv/linux/i386/i586/pthread_rwlock_unlock.S | 19 -- .../sysv/linux/i386/i586/pthread_rwlock_wrlock.S | 19 -- .../sysv/linux/i386/i686/pthread_rwlock_rdlock.S | 19 -- .../linux/i386/i686/pthread_rwlock_timedrdlock.S | 19 -- .../linux/i386/i686/pthread_rwlock_timedwrlock.S | 19 -- .../sysv/linux/i386/i686/pthread_rwlock_unlock.S | 20 -- .../sysv/linux/i386/i686/pthread_rwlock_wrlock.S | 19 -- .../unix/sysv/linux/x86_64/pthread_rwlock_rdlock.S | 177 ------------- .../sysv/linux/x86_64/pthread_rwlock_timedrdlock.S | 274 --------------------- .../sysv/linux/x86_64/pthread_rwlock_timedwrlock.S | 266 -------------------- .../unix/sysv/linux/x86_64/pthread_rwlock_unlock.S | 126 ---------- .../unix/sysv/linux/x86_64/pthread_rwlock_wrlock.S | 165 ------------- 20 files changed, 2204 deletions(-) delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_rdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedrdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedwrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_unlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_wrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_rdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_timedrdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_timedwrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_unlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i586/pthread_rwlock_wrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_rdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_timedrdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_timedwrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_unlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/i386/i686/pthread_rwlock_wrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_rdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedrdlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedwrlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_unlock.S delete mode 100644 nptl/sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_wrlock.S
