PR middle-end/54860 - Make sure attributes hash table is created
On targets cris-elf, alpha and sparc (for instance) it can happen that
the attribute_tables variable is empty for fortran. Thus
register_scoped_attributes (called by init_attributes) won't call
register_scoped_attributes, so the hash table member of
scoped_attributes is not created.
Later when we try to e.g, lookup an attribute by calling
lookup_scoped_attribute_spec, that NULL member hash table comes to
byte us as htab_find_with_hash crashes.
This patch fixes this by ensuring in register_scoped_attributes that
the hash table is created.
Tested on cris-elf, x86_64-unknown-linux-gnu against trunk and some
commenters on the bug bootstrapped it on alpha and sparc.
gcc/
* attribs.c (register_scoped_attributes): Ensure the attribute
hash table is created.
