This patch doesn't include documentation patches for the new target
hooks or the new parameters.
There is no separate documentation for *any* of the target hooks. Still,
comments for the new hooks present in target.h. As for the two new
parameters, submitted patch contains hunks for patching
gcc/doc/invoke.texi .
HUH? what is in doc/tm.texi then?
Like TARGET_ALIGN_ANON_BITFIELDS:
@deftypefn {Target Hook} bool TARGET_ALIGN_ANON_BITFIELDS (void)
When @code{PCC_BITFIELD_TYPE_MATTERS} is true this hook will determine
whether unnamed bitfields affect the alignment of the containing
structure. The hook should return true if the structure should inherit
the alignment requirements of an unnamed bitfield's type.
@end deftypefn
