calls.c (expand_call): Try to do a tail call for thunks at -O0 too.
* calls.c (expand_call): Try to do a tail call for thunks at -O0 too.
* cgraph.h (struct cgraph_thunk_info): Add indirect_offset.
(cgraph_node::create_thunk): Add indirect_offset parameter.
(thunk_adjust): Likewise.
* cgraph.c (cgraph_node::create_thunk): Add indirect_offset parameter
and initialize the corresponding field with it.
(cgraph_node::dump): Dump indirect_offset field.
* cgraphclones.c (duplicate_thunk_for_node): Deal with indirect_offset.
* cgraphunit.c (cgraph_node::analyze): Be prepared for external thunks.
(thunk_adjust): Add indirect_offset parameter and deal with it.
(cgraph_node::expand_thunk): Deal with the indirect_offset field and
pass it to thunk_adjust. Do not call the target hook if it's non-zero
or if the thunk is external or local. Fix formatting. Do not chain
the RESULT_DECL to BLOCK_VARS. Pass the static chain to the target,
if any, in the GIMPLE representation.
* ipa-icf.c (sem_function::equals_wpa): Deal with indirect_offset.
* lto-cgraph.c (lto_output_node): Write indirect_offset field.
(input_node): Read indirect_offset field.
* tree-inline.c (expand_call_inline): Pass indirect_offset field in the
call to thunk_adjust.
* tree-nested.c (struct nesting_info): Add thunk_p field.
(create_nesting_tree): Set it.
(convert_all_function_calls): Copy static chain from targets to thunks.
(finalize_nesting_tree_1): Return early for thunks.
(unnest_nesting_tree_1): Do not finalize thunks.
(gimplify_all_functions): Do not gimplify thunks.
cp/
* method.c (use_thunk): Adjust call to cgraph_node::create_thunk.
ada/
* gcc-interface/decl.c (is_cplusplus_method): Do not require C++
convention on Interfaces.
* gcc-interface/trans.c (Subprogram_Body_to_gnu): Try to create a
bona-fide thunk and hand it over to the middle-end.
(get_controlling_type): New function.
(use_alias_for_thunk_p): Likewise.
(thunk_labelno): New static variable.
(make_covariant_thunk): New function.
(maybe_make_gnu_thunk): Likewise.
* gcc-interface/utils.c (finish_subprog_decl): Set DECL_CONTEXT of the
result DECL here instead of...
(end_subprog_body): ...here.
