as a parameterless function call, but none of the candidate
interpretations is parameterless, and there is a hidden homonym
of the prefix that is a package.
* sem_ch8.adb (Find_Selected_Component): If the prefix might be
interpreted as a parameterless function call and its analysis
fails, do not call Analyze_Selected_Component.

sem_dim.adb (Analyze_Dimension): Analyze object declaration and identifier nodes that do not come from source...

2017-01-19  Ed Schonberg  <schonberg@adacore.com>

* sem_dim.adb (Analyze_Dimension): Analyze object declaration and
identifier nodes that do not come from source, to handle properly
dimensionality check within an inlined body which inclddes both
original operands and rewritten operands. This removes spurious
dimensionality errors in the presence of front-end inlining,
as well as in SPARK mode.

[expand] Fix for PR rtl-optimization/79121 incorrect expansion of extend plus left shift

    When generating a shift from an extended value moving from one to two
    machine registers, the type of the right shift is for the most
    significant word should be determined by the signedness of the inner
    type, not the signedness of the result type.

    gcc:
        PR rtl-optimization/79121
        * expr.c (expand_expr_real_2, case LSHIFT_EXPR): Look at the signedness
        of the inner type when shifting an extended value.

        * gcc.c-torture/execute/pr79121.c: New test.
