Andrew Geisslerc182c622020-05-15 14:13:32 -05004Subject: [PATCH] 64-bit multilib hack.
Andrew Geissler82c905d2020-04-13 13:39:40 -05005
6GCC has internal multilib handling code but it assumes a very specific rigid directory
7layout. The build system implementation of multilib layout is very generic and allows
8complete customisation of the library directories.
9
10This patch is a partial solution to allow any custom directories to be passed into gcc
11and handled correctly. It forces gcc to use the base_libdir (which is the current
12directory, "."). We need to do this for each multilib that is configured as we don't
13know which compiler options may be being passed into the compiler. Since we have a compiler
14per mulitlib at this point that isn't an issue.
15
16The one problem is the target compiler is only going to work for the default multlilib at
17this point. Ideally we'd figure out which multilibs were being enabled with which paths
18and be able to patch these entries with a complete set of correct paths but this we
19don't have such code at this point. This is something the target gcc recipe should do
20and override these platform defaults in its build config.
21
22Do same for riscv64 and aarch64
