* c-common.h (genrtl_expr_stmt_value): Declare.
* c-semantics.c (genrtl_goto_stmt): Redirect to...
(genrtl_goto_stmt_value): ... this new function. Pass new
argument down to expand_expr_stmt_value, taking
TREE_ADDRESSABLE into account.
* c-common.c (c_expand_expr): Mark the last EXPR_STMT of a
STMT_EXPR as addressable, i.e., one whose result we want.
* expr.c (expand_expr): Don't save expression statement value
of labeled_blocks or loop_exprs.
* stmt.c (expand_expr_stmt): Redirect to...
(expand_expr_stmt_value): ... this new function. Use new
argument to tell whether to save expression value.
(expand_end_stmt_expr): Reset last_expr_type and
last_expr_value if we don't have either.
* tree-inline.c (declare_return_variable): Mark its use
statement as addressable.
* tree.h: Document new use of TREE_ADDRESSABLE.
(expand_expr_stmt_value): Declare.
From-SVN: r48456
* c-decl.c (duplicate_decls): Revert rth's patch. If newdecl
is in a different binding level, get its abstract origin to be
olddecl.
* tree-inline.c (expand_call_inline): Move DECL_INITIAL sanity
check earlier.
* tree.c (get_callee_fndecl): Follow DECL_ABSTRACT_ORIGIN if
DECL_INITIAL is NULL.
From-SVN: r47610
* tree-inline.c (inlinable_function_p): Leave it up to the
front-end to turn -finline-functions into DECL_INLINE set for all
functions.
From-SVN: r46292
* Makefile.in (c-decl.o): Depend on tree-inline.h.
(c-lang.o): Likewise, as well as insn-config.h and integrate.h.
* c-decl.c: Include tree-inline.h.
(c_expand_body): Call optimize_inline_calls. Determine whether
a function is inlinable upfront, and only clear
DECL_SAVED_TREE, DECL_INITIAL and DECL_ARGUMENTS if it isn't.

(c_disregard_inline_limits): New function.

Don't inline trees when instrumenting functions.
(c_init): Initialize lang_disregard_inline_limits and
lang_cannot_inline_tree_fn.
* tree-inline.c (initialize_inlined_parameters): Handle calls
with fewer arguments than declared parameters, and fewer
parameters than passed arguments. Don't assume value is a
DECL.
(declare_return_variable): Convert return value back to the
original type, if it was promoted.
(tree_inlinable_function_p): New function.
(inlinable_function_p): Don't look at DECL_INLINE if we're
inlining all functions. Make it work with a NULL id.
Re-check DECL_UNINLINABLE after language-specific checks.
(varargs_function_p): Move back to cp/tree.c.
* tree-inline.h (tree_inlinable_function_p): Declare it.
(varargs_function_p): Removed declaration.
* integrate.h (function_attribute_inlinable_p): Declare it.
* integrate.c (function_attribute_inlinable_p): Export it.
(save_for_inline): Don't bother to prepare argvec when not
inlining.
* cse.c (check_for_label_ref): Don't check deleted labels.

* tree-inline.c: Include headers needed for the functions moved in.
(struct inline_data, INSNS_PER_STMT): Moved from cp/optimize.c.
(remap_decl, remap_block, copy_scopy_stmt, copy_body_r): Likewise.
(copy_body, initialize_inlined_parameters): Likewise.
