+ [BZ #14132]
+ * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto.
+ [IS_IN_rtld] (_dl_argv_internal): Do not declare.
+ (rtld_progname): Make macro definition unconditional.
+ * elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of
+ INTDEF.
+ (dlmopen_doit): Do not use INTUSE with _dl_argv.
+ (dl_main): Likewise.
+ * elf/dl-sysdep.c (_dl_sysdep_start): Likewise.
+ * sysdeps/alpha/dl-machine.h (RTLD_START): Use __GI__dl_argv
+ instead of _dl_argv_internal.
+ * sysdeps/powerpc/powerpc32/dl-start.S (_dl_start_user): Use
+ __GI__dl_argv instead of INTUSE(_dl_argv).
+ * sysdeps/powerpc/powerpc64/dl-machine.h (RTLD_START): Use
+ __GI__dl_argv instead of _dl_argv_internal.
+
* soft-fp/op-common.h (_FP_TO_INT_ROUND): New macro.
* soft-fp/double.h [_FP_W_TYPE_SIZE < 64] (FP_TO_INT_ROUND_D): New
macro.
