If you create a toolchain with the target alphaev68-unknown-linux-gnu, gcc
will use the -mcpu=ev67 by default when compiling.  Some software packages
(like gmp) will use this target info to decide that it may freely use
assembly code that targets ev67+.  The trouble comes in when trying to
compile that pure assembly code.

While gcc will use -mcpu=ev67 just fine, it will invoke gas without an
-mev67 option, so the assembler will default to the lowest common
denominator -- ev4 in this case.  Inline assembly in C code is normally
just peachy because gcc's assembler output will start with ".arch <cpu>"
and the assembler will accept that.  But if the hand coded assembly code
lacks that .arch, you easily end up with errors like so:
opcode `cttz' not supported for target <all>

While the assembly code could/should be fixed to explicitly output the
.arch directive, I think it's reasonable to expect this to work:
echo 'cttz $20,$21' | gcc -x assembler -c - -o /dev/null -mcpu=ev67

This simple patch implements that, although I guess it is a bit redundant
in the default case where gcc outputs .arch.  Perhaps that should all be
punted in favor of a specs-only approach.  Considering gas respects .arch
in the code over the command line, it should also make things more natural.
The command line is processed in the standard/expected way -- gcc defaults
the -m option while user's custom -mcpu/-Wa,-m options come after, and the
guy writing the assembly code is free to use .arch to override everything
else.

* sem_ch3.adb (Is_Visible_Component): Component is visible
in a derived type if inherited through an ancestor that has a
partial view of the original type holding the component, if the
full view of that original type is in scope.
* sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.

2015-05-28  Bob Duff  <duff@adacore.com>

* sem_util.adb (Requires_Transient_Scope): For definite untagged
subtypes, we should never have to use the secondary stack. This moves
toward that goal. But there are still cases that don't work.
Here, we move the check for Is_Definite first, but add a
special-purpose check for Has_Discrim_Dep_Array.

PR tree-optimization/66142
* tree-ssa-sccvn.c (vn_reference_lookup_3): Handle non-GIMPLE
values better in memcpy destination handling.  Handle non-aliasing
we discover here.

* gcc.dg/tree-ssa/ssa-fre-44.c: Fixup.
