Subject: [PATCH V5 2/5] Use linux_get_siginfo_type_with_fields for x86
Date: Fri, 22 Jan 2016 15:18:00 -0000 [thread overview]
Message-ID: <1453474456-13169-3-git-send-email-walfred.tedeschi@intel.com> (raw)
In-Reply-To: <1453474456-13169-1-git-send-email-walfred.tedeschi@intel.com>
Use linux_get_siginfo_type_with_fields for adding bound fields on
segmentation fault for i386/amd64 siginfo.
2016-01-15 Walfred Tedeschi <walfred.tedeschi@intel.com>
gdb/ChangeLog:
* linux-tdep.h (linux_get_siginfo_type_with_fields): Make extern.
* linux-tdep.c (linux_get_siginfo_type_with_fields): Make extern.
* i386-linux-tdep.h (x86_linux_get_siginfo_type): New
function.
* amd64-linux-tdep.c (amd64_linux_init_abi_common): Add
x86_linux_get_siginfo_type for the amd64 abi.
* i386-linux-tdep.c (x86_linux_get_siginfo_type): New
Function.
(i386_linux_init_abi): Add new function at the i386 ABI
initialization.
