Subject: [PATCH 13/14] implement dlset_object_base() function
Date: Thu, 18 May 2023 13:28:53 +0500 [thread overview]
Message-ID: <20230518082854.3903342-14-stsp2@yandex.ru> (raw)
In-Reply-To: <20230518082854.3903342-1-stsp2@yandex.ru>
`int dlset_object_base(void *handle, void *addr)' - new function to
set the new base address of an unrelocated object, after it was moved.
Returns error if the object is already relocated. The base address
set by this function, will be used when relocation is performed.
The test-suite was run on x86_64/64 and showed no regressions.
Signed-off-by: Stas Sergeev <stsp2@yandex.ru>
