From 57803a3c60f399772907ac306f6eefd9fc83fb15 Mon Sep 17 00:00:00 2001 From: Walfred Tedeschi Date: Tue, 19 Nov 2013 12:19:30 +0000 Subject: Fix conditions in creating a bitfield. Bitfields are represented by intervals [start, begin]. It means that for an interval comprised by only one bit start and end will be equal. The present condition does not always hold. On the other hand in target-description.c (tdesc_gdb_type) bitfield is created when "f->type" is null. The routine maint_print_maint_print_c_tdesc_cmd is modified to follow the same strategy. 2013-11-20 Walfred Tedeschi * target-descriptions.c (maint_print_maint_print_c_tdesc_cmd): Modified logic of creating a bitfield to be in sync with tdesc_gdb_type. testsuite/ * gdb.xml/maint_print_struct.xml (bitfield): Added bitfield having start and end equal 0.
