Subject: [PATCH 02/23] New gdbarch memory tagging hooks
Date: Wed, 15 Jul 2020 16:44:52 -0300 [thread overview]
Message-ID: <20200715194513.16641-3-luis.machado@linaro.org> (raw)
In-Reply-To: <20200715194513.16641-1-luis.machado@linaro.org>
We need some new gdbarch hooks to help us manipulate memory tags without having
to have GDB calls the target methods directly.
This patch adds the following hooks:
gdbarch_memtag_to_string
--
Returns a printable string corresponding to the tag.
gdbarch_tagged_address_p
--
Checks if a particular address is protected with memory tagging.
gdbarch_memtag_mismatch_p
--
Checks if there is a mismatch between the logical tag of a pointer and the
allocation tag.
gdbarch_set_memtags:
--
Sets either the allocation tag or the logical tag for a particular value.
gdbarch_get_memtag:
--
Gets either the allocation tag or the logical tag for a particular value.
gdbarch_granule_size
--
Sets the memory tag granule size, which represents the number of bytes a
particular allocation tag covers. For example, this is 16 bytes for
AArch64's MTE.
I've used struct value as opposed to straight CORE_ADDR so other architectures
can use the infrastructure without having to rely on fixed types.
gdb/ChangeLog:
YYYY-MM-DD Luis Machado <luis.machado@linaro.org>
* arch-utils.c (default_memtag_to_string, +default_tagged_address_p)
(default_memtag_mismatch_p, default_set_memtags)
(default_get_memtag): New functions.
* arch-utils.h (default_memtag_to_string, default_tagged_address_p)
(default_memtag_mismatch_p, default_set_memtags)
(default_get_memtag): New prototypes.
* gdbarch.c: Regenerate.
* gdbarch.h: Regenerate.
* gdbarch.sh (memtag_to_string, tagged_address_p, memtag_mismatch_p)
(set_memtags, get_memtag, memtag_granule_size): New gdbarch hooks.
(enum memtag_type): New enum.
