From 5524b5250e319f41933605420e9526fb74cfb9ae Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Wed, 14 Jun 2017 14:24:03 +0200 Subject: [PATCH] Fix register selection in var-access.exp The new test var-access.exp causes FAILs on i686. This is because the test chooses the wrong name for DWARF register number 1: It uses "edx" (which corresponds to DWARF register number 2), but should have used "ecx" instead. Also, the current logic in var-access.exp does not correctly distinguish between a 64-bit and a 32-bit program on an x86-64 target. It uses the 64-bit register names for both. These problems are fixed. In order to address the latter, the convenience macros is_*_target are exploited where appropriate. gdb/testsuite/ChangeLog: * gdb.dwarf2/var-access.exp: Use register name ecx instead of edx on 32-bit x86 targets. Exploit is_*_target macros where appropriate. --- gdb/testsuite/ChangeLog | 6 ++++++ gdb/testsuite/gdb.dwarf2/var-access.exp | 10 +++++----- 2 files changed, 11 insertions(+), 5 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index e5d303c..ff54199 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,9 @@ +2017-06-14 Andreas Arnez + + * gdb.dwarf2/var-access.exp: Use register name ecx instead of edx + on 32-bit x86 targets.
