Subject: [PATCH] libgomp: Allow overriding via 'GOMP_OFFLOAD_PLUGINS' the
configured set of libgomp plugins
This can be useful for testing the same libgomp build on several machines, with
different offload capabilities/configurations.
This is subject to change, and thus intentionally not documented.
libgomp/
* target.c [PLUGIN_SUPPORT] (gomp_target_init): Allow overriding
via 'GOMP_OFFLOAD_PLUGINS' the configured set of libgomp plugins.
