# This test demonstrates "layered" multilib in which more than one
|
||
|
|
# multilib is matched.
|
||
|
|
# For example a multilib containing only a no-exceptions libc++ could
|
||
|
|
# be layered on top of a multilib containing C libs. This avoids the
|
||
|
|
# need to duplicate the C library for every libc++ variant.
|
||
|
|
# However -fno-exceptions is not yet supported for multilib selection
|
||
|
|
# so we use a more contrived -mfloat-abi example instead.
