Upstream-Status: Inappropriate [embedded specific]
|
|
|
|
GCC has internal multilib handling code but it assumes a very specific rigid directory
|
|
layout. The build system implementation of multilib layout is very generic and allows
|
|
complete customisation of the library directories.
|
|
|
|
This patch is a partial solution to allow any custom directories to be passed into gcc
|
|
and handled correctly. It forces gcc to use the base_libdir (which is the current
|
|
directory, "."). We need to do this for each multilib that is configured as we don't
|
|
know which compiler options may be being passed into the compiler. Since we have a compiler
|
|
per mulitlib at this point that isn't an issue.
|
|
|
|
The one problem is the target compiler is only going to work for the default multlilib at
|
|
this point. Ideally we'd figure out which multilibs were being enabled with which paths
|
|
and be able to patch these entries with a complete set of correct paths but this we
|
|
don't have such code at this point. This is something the target gcc recipe should do
|
|
and override these platform defaults in its build config.
