We need to be able to set the static chain on a few calls within the
Go runtime, so expose this with __builtin_call_with_static_chain.
* c-family/c-common.c (c_common_reswords): Add
__builtin_call_with_static_chain.
* c-family/c-common.h (RID_BUILTIN_CALL_WITH_STATIC_CHAIN): New.
* c/c-parser.c (c_parser_postfix_expression): Handle it.
* doc/extend.texi (__builtin_call_with_static_chain): Document it.
From-SVN: r217771
And, at the same time, allow indirect calls to have a static chain.
We'll always eliminate the static chain if we can prove it's unused.
* calls.c (prepare_call_address): Allow decl or type for first arg.
(expand_call): Pass type to prepare_call_address if no decl.
* gimple-fold.c (gimple_fold_call): Eliminate the static chain if
the function doesn't use it; fold it otherwise.
* gimplify.c (gimplify_call_expr): Gimplify the static chain.
* tree-cfg.c (verify_gimple_call): Allow a static chain on indirect
function calls.
From-SVN: r217770
As opposed to always being a decl. This is a prerequisite
to allowing the static chain to be loaded for indirect calls.

DECL_STATIC_CHAIN.

* config/i386/i386.c (ix86_static_chain): Allow decl or type
