From 06253dd31f4ce1b549d8ba0755dbb71cfb748772 Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Tue, 31 Aug 2010 18:11:48 +0000 Subject: [PATCH] gdb/ Make linux_get_siginfo_type `type *' unique. * linux-tdep.c (linux_gdbarch_data_handle, struct linux_gdbarch_data) (init_linux_gdbarch_data, get_linux_gdbarch_data): New. (linux_get_siginfo_type): New variable linux_gdbarch_data. Initialize it. Use linux_gdbarch_data->siginfo_type as a persistent storage.
