Driver: Provide a spec to insert rpaths for compiler lib dirs.
This provides a spec to insert "-rpath DDD" for each DDD corresponding
to a compiler startfile directory. This allows a target to use @rpath
as the install path for libraries, and have the compiler provide the
necessary rpath to handle this.
Embed real paths, not relative ones.
We embed a runpath for every path in which libraries might be found. This
change ensures that we embed the actual real path and not a relative one from
the compiler's version-specific directory.
e.g.
/opt/distro/gcc-11-3Dr0/lib
instead of:
/opt/distro/gcc-11-3Dr0/lib/gcc/x86_64-apple-darwin19/11.3.0/../../..
This ensures that if we install, for example, 11.4.0 (and delete the 11.3.0
installation) exes built by 11.3 would continue to function (providing, of course
that 11.4 does not bump any SO names).
gcc/ChangeLog:
* gcc.cc (RUNPATH_OPTION): New.
(do_spec_1): Provide '%P' as a spec to insert rpaths for
each compiler startfile path.
