	* collect2.c (main): Don't call fatal_error before
	diagnostic_initialize.
	* lto-wrapper.c (main): Likewise.

	PR sanitizer/63879
	* fold-const.c (negate_expr_p) <case NEGATE_EXPR>: Return
	!TYPE_OVERFLOW_SANITIZED.
	(fold_negate_expr) <case INTEGER_CST>: Fold when overflow
	does not trap and when overflow wraps, or when SANITIZE_SI_OVERFLOW
	is 0.

	* c-c++-common/ubsan/pr63879-1.c: New test.
	* c-c++-common/ubsan/pr63879-2.c: New test.

        * MAINTAINERS (Write After Approval): Add myself.

This is simple patch to add more conditional macros defined in ACLE 2.0.

2014-10-17  Renlin Li  <Renlin.Li@arm.com>

    * config/aarch64/aarch64.h (TARGET_CPU_CPP_BUILTINS): Define __ARM_FP_FAST,
    __ARM_FEATURE_FMA, __ARM_FP, __ARM_FEATURE_NUMERIC_MAXMIN, __ARM_NEON_FP.

Make TARGET_STATIC_CHAIN allow a function type

As opposed to always being a decl.  This is a prerequisite
to allowing the static chain to be loaded for indirect calls.

        * targhooks.c (default_static_chain): Remove check for
        DECL_STATIC_CHAIN.
        * config/moxie/moxie.c (moxie_static_chain): Likewise.
        * config/i386/i386.c (ix86_static_chain): Allow decl or type
        as the first argument.
        * config/xtensa/xtensa.c (xtensa_static_chain): Change the name
        of the unused first parameter.
        * doc/tm.texi (TARGET_STATIC_CHAIN): Document the first parameter
        may be a type.
        * target.def (static_chain): Likewise.

Allow the front-end to create calls with a static chain

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.

Allow the static chain to be set from C

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.

Merge branch 'rth/ffi' into merge
Use the static chain as the closure parameter from Go

This is not a standalone patch; it only touches the Go front end.
Further changes are required for the Go runtime.
libgo: Use the static chain for the closure

Doesn't delete the __go_get/set_closure routines yet, as they're
still referenced by the ffi code, to be updated in another patch.
libgo: Use the new libffi interfaces for Go
libgo: Remove __go_get/set_closure
