Hi!
This was found by grepping through the source and reading -Dyesterday -rHEAD
CVS diff.
GLIBC_PRIVATE patch will be next.
2002-02-01 Jakub Jelinek <jakub@redhat.com>
* sysdeps/generic/dl-procinfo.c: New file.
* sysdeps/generic/ldsodefs.h (_dl_load_lock): Remove duplicate
definition.
* sysdeps/ia64/hp-timing.h: Move _dl_hp_timing_overhead in
_rtld_global struct.
* sysdeps/sparc/sparc32/sparcv9/hp-timing.h: Likewise.
* sysdeps/sparc/sparc64/hp-timing.c: Likewise.
* sysdeps/sparc/sparc64/hp-timing.h: Likewise.
* sysdeps/sparc/sparc64/Makefile: Make hp-timing static only.
* sysdeps/unix/sysv/aix/init-first.c (_dl_fpu_control,
_dl_fpu_control_set): Remove unused externs.
* sysdeps/unix/sysv/linux/sparc/sparc32/dl-procinfo.c: New file.
* sysdeps/unix/sysv/linux/sparc/sparc64/dl-procinfo.c: New file.
* sysdeps/unix/sysv/linux/sparc/sparc32/dl-procinfo.h: Move procinfo
related variables in _rtld_global struct.
* sysdeps/unix/sysv/linux/sparc/sparc64/dl-procinfo.h: Likewise.
* sysdeps/unix/sysv/linux/init-first.c (_dl_fpu_control_set): Remove
unused extern.
