obstack.h __PTR_ALIGN vs. ubsan
Current ubsan complains on every use of __PTR_ALIGN (when ptrdiff_t is

simplifying __BPTR_ALIGN for the usual case. I've continued to use

openmp: Fix OpenMP expansion of scope with non-fallthrugh body [PR102415]
I've used function for omp single expansion also for omp scope. That is
mostly ok, but as the testcase shows, there is one important difference.
The omp single expansion always has a fallthru body, because it during
omp lowering expands the body as if wrapped in an if to simulate that
one thread runs the body and others wait (unless nowait) until it completes
and continue. omp scope is invoked by all threads and so if the body
is non-fallthru, the barrier (unless nowait) at the end will not be reached
by any of the threads.
The following patch fixes that by handling the case where cfg pass optimizes
away the exit bb of it gracefully.

c++: fix template instantiation comparison in redeclarations
This change fixes a primordial c++11 frontend defect where function template
redeclarations with trailing return types that used dependent
sizeof/alignof/noexcept expressions in template value arguments failed to
compare as equivalent to the identical primary template declaration. By
forcing structural AST comparison of the template arguments, we no longer
require TYPE_CANONICAL to match in this case. The new canon-type-{15..18}.C
tests failed with all prior GCC versions, where the redeclarations were
incorrectly reported as ambiguous overloads. The new dependent-name{15,16}.C
tests are regression tests for sneaky problems encountered during
development of this fix. Note that this fix does not address the use of parm

superficially similar longstanding defect).

path solver: Add related SSAs to solvable set.
The path solver takes an initial set of SSA names which are deemed
interesting. These are then solved along the path. Adding any copies
of said SSA names to the list of interesting names yields significantly
better results. This patch adds said copies to the already provided
list.
Currently this code is guarded by "m_resolve", which is the more

arm: pass architecture extensions to assembler if supported
When I originally added the new extended architecture features support
to GCC, the assembler was unable to parse the new feature lists on the
command-line and would throw an error. This has now been fixed in GAS
and the behaviour is the same as GCC.
So this patch adds a configure-time test for the assembler in use to
detect that it is recent enough to support this behaviour and then
enables passing the architecture extensions to the assembler when this
is the case.
Although the assembly output generated by GCC does not rely on this,
this should ease some issues when using GCC as a driver for compiling
source written directly in assembly language when the programmer was
expecting the appropriate options to be passed on the command line.
