2021-09-07	ctfc: add function to lookup CTF ID of a TREE type	David Faust	1	-0/+16
	Add a new function, ctf_lookup_tree_type, to return the CTF type ID associated with a type via its is TREE node. The function is exposed via a prototype in ctfc.h. gcc/ChangeLog: * ctfc.c (ctf_lookup_tree_type): New function. * ctfc.h: Likewise.
2021-09-07	ctfc: externalize ctf_dtd_lookup	David Faust	1	-1/+1
	Expose the function ctf_dtd_lookup, so that it can be used by the BPF CO-RE machinery. The function is no longer static, and an extern prototype is added in ctfc.h. gcc/ChangeLog: * ctfc.c (ctf_dtd_lookup): Function is no longer static. * ctfc.h: Analogous change.
