File 0005-S390-Name-invisible-registers-with-the-empty-string-.patch of Package gdb.783
Part of fate#318039 From 87de11c05253566abb04479a4842cc934d0c822e Mon Sep 17 00:00:00 2001 From: Andreas Arnez <arnez@linux.vnet.ibm.com> Date: Wed, 4 Mar 2015 10:40:41 +0100 Subject: [PATCH] S390: Name "invisible" registers with the empty string instead of NULL When adding vector register support to GDB, s390_register_name() was added to suppress the right halves of the first 16 vector registers. However, that function returned NULL instead of an empty string in such a case. This leads to an incomplete list of registers returned by "complete info registers ", because completion stops at the first NULL return value from user_reg_map_regnum_to_name(). gdb/ChangeLog: * s390-linux-tdep.c (s390_register_name): Return empty string instead of NULL for registers that shouldn't be visible. --- gdb/ChangeLog | 5 +++++ gdb/s390-linux-tdep.c | 6 +++--- 2 files changed, 8 insertions(+), 3 deletions(-) Index: gdb-7.9.1/gdb/s390-linux-tdep.c =================================================================== --- gdb-7.9.1.orig/gdb/s390-linux-tdep.c 2015-07-10 16:18:36.000000000 +0200 +++ gdb-7.9.1/gdb/s390-linux-tdep.c 2015-07-10 16:19:20.000000000 +0200 @@ -263,15 +263,15 @@ regnum_is_vxr_full (struct gdbarch_tdep && regnum <= tdep->v0_full_regnum + 15); } -/* Return the name of register REGNO.
