Hi,
This patch adds always_inline to the d_langhook_common_attribute_table.
The attribute is not directly accessible from user code, rather it is
indirectly added from the @forceinline attribute. Even so, a handler
should be present for it to prevent false positive warnings.
Said warnings are not something that could happen currently, but will
become a problem from fixing PR90136 later.
Bootstrapped and tested on x86_linux-gnu. Committed to mainline.
Regards
Iain
