[COMMITTED] bpf: mark/remove unused arguments and remove an unused function
Commit Message
This patch does a little bit of cleanup by removing some unused
arguments, or marking them as unused. It also removes the function
ctfc_debuginfo_early_finish_p and the corresponding hook macro
definition, which are not used by GCC.
gcc/
* config/bpf/bpf.c (bpf_handle_preserve_access_index_attribute):
Mark arguments `args' and flags' as unused.
(bpf_core_newdecl): Remove unused local `newdecl'.
(bpf_core_newdecl): Remove unused argument `loc'.
(ctfc_debuginfo_early_finish_p): Remove unused function.
(TARGET_CTFC_DEBUGINFO_EARLY_FINISH_P): Remove definition.
(bpf_core_walk): Do not pass a location to bpf_core_newdecl.
