Subject: [PATCH 0/3] Espressif xtensa chips multilib
Date: Thu, 20 Jul 2023 14:34:04 +0000 [thread overview]
Message-ID: <485a6a6c62a8632d9e3ac44b2d8fd935c0e0a78b.camel@espressif.com> (raw)
This patch series introduces multilib support for Espressif XTENSA chips in gcc.
The addition of the "-mdynconfig=" option was necessary because the existing
environment variable XTENSA_GNU_CONFIG cannot be utilized for implementing multilib.
This is because multilib operates with gcc options rather than environment variables.
It is not possible to use full path in "-mdynconfig=" because it could be different
on users machines and because multilib syntax already reserves the directory
delimiter character. So, it designed to contain dynconfig filename which would not
change in toolchain.
Also, the XTENSA_GNU_CONFIG environment variable usage was changed to include both
the dynconfig file fullpath or dynconfigs directory. This change was made to overcome
the limitations of modifying LD_LIBRARY_PATH on macOS host machines.
