Subject: Linker script and alias to a versioned symbol
Date: Fri, 10 Feb 2023 13:35:08 -0500 [thread overview]
Message-ID: <CAAJF+LnQ4Du-f0MDrj05MJWYahv8-Oby5hA4YFtzjgpAvVa=2w@mail.gmail.com> (raw)
Hi,
I would like to know whether it is possible, in a linker script, to
define an alias to a versioned symbol.
As an example, let me use these two versioned symbols in glibc:
XXXX: 00000000000XXXX 119 FUNC GLOBAL DEFAULT 15
clock_gettime@GLIBC_2.2.5
XXXX: 00000000000XXXX 119 FUNC GLOBAL DEFAULT 15
clock_gettime@@GLIBC_2.17
In a linker script, is it possible to make sure that a call to
clock_gettime ends up invoking clock_gettime@GLIBC_2.2.5 ?
I am familiar with how `__asm__(".symver SYM,SYM@GLIBC_VERSION");`
works but that's not what I am looking for. I would like to know if
there is a way to achieve this goal using only a linker script and
nothing else.
I tried something like this:
PROVIDE( clock_gettime = clock_gettime@GLIBC_2.2.5 );
But it doesn't seem to work. Maybe the '@' is an invalid char above?
Thanks
