[nvptx, offloading] Determine default workers at runtime
Currently, if the user doesn't specify the number of workers for an openacc
region, the compiler hardcodes it to a default value.
This patch removes this functionality, such that the libgomp runtime can decide
on a default value.

libgo: prune sighandler frames in runtime.sigprof
When writing stack frames to the pprof CPU profile machinery, it is
very important to insure that the frames emitted do not contain any
frames corresponding to artifacts of the profiling process itself
(signal handlers, sigprof, etc). This patch changes runtime.sigprof to
strip out those frames from the raw stack generated by
"runtime.callers".

libsanitizer: Mark REAL(swapcontext) with indirect_return attribute on x86
Cherry-pick compiler-rt revision 337603:
When shadow stack from Intel CET is enabled, the first instruction of all
indirect branch targets must be a special instruction, ENDBR.
lib/asan/asan_interceptors.cc has
...
int res = REAL(swapcontext)(oucp, ucp);
...
REAL(swapcontext) is a function pointer to swapcontext in libc. Since
swapcontext may return via indirect branch on x86 when shadow stack is
enabled, as in this case,
int res = REAL(swapcontext)(oucp, ucp);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This function may be
returned via an indirect branch.
Here compiler must insert ENDBR after call, like
call *bar(%rip)
endbr64
I opened an LLVM bug:
https://bugs.llvm.org/show_bug.cgi?id=38207
to add the indirect_return attribute so that it can be used to inform
compiler to insert ENDBR after REAL(swapcontext) call. We mark
REAL(swapcontext) with the indirect_return attribute if it is available.
This fixed:

Fix ceil_log2(0) (PR 86644)
This PR shows a pathological case in which we try SLP vectorisation on
dead code. We record that 0 bits of the result are enough to satisfy
all users (which is true), and that led to precision being 0 in:
static unsigned int
vect_element_precision (unsigned int precision)
{
precision = 1 << ceil_log2 (precision);
return MAX (precision, BITS_PER_UNIT);
}
ceil_log2 (0) returned 64 rather than 0, leading to 1 << 64, which is UB.

Add initial version of C++17 <memory_resource> header
This is missing the synchronized_pool_resource and

This is a new implementation, not based on the existing code in

The constant_init kluge in src/c++17/memory_resource.cc is apparently

Fix segfault in -fsave-optimization-record (PR tree-optimization/86636)
There are various ways that it's possible for a gimple statement to
have an UNKNOWN_LOCATION, and for that UNKNOWN_LOCATION to be wrapped
in an ad-hoc location to capture inlining information.
For such a location, LOCATION_FILE (loc) is NULL.
Various places in -fsave-optimization-record were checking for
loc != UNKNOWN_LOCATION
and were passing LOCATION_FILE (loc) to code that assumed a non-NULL
filename, thus leading to segfaults for the above cases.
This patch updates the tests to use
LOCATION_LOCUS (loc) != UNKNOWN_LOCATION
instead, to look through ad-hoc location wrappers, fixing the segfaults.
It also adds various assertions to the affected code.

compiler: do order_evaluations before remove_shortcuts
In remove_shortcuts, the shortcut expressions (&&, ||) are
rewritten to if statements, which are lifted out before the
statement containing the shortcut expression. If the containing
statement has other (sub)expressions that should be evaluated
before the shortcut expression, which has not been lifted out,
this will result in wrong evaluation order.
For example, F() + G(A() && B()), the evaluation order per spec
is F, A, B (if A returns true), G. If we lift A() and B() out
first, they will be called before F, which is wrong.
To fix this, we split order_evaluations to two phases. The first
phase, which runs before remove_shortcuts, skips shortcut
expressions' components. So it won't lift out subexpressions that
are evaluated conditionally. The shortcut expression itself is
ordered, since it may have side effects. Then we run
remove_shortcuts. At this point the subexpressions that should be
evaluated before the shortcut expression are already lifted out.
remove_shortcuts also runs the second phase of order_evaluations
to order the components of shortcut expressions, which were
skipped during the first phase.
Reorder the code blocks of remove_shortcuts and order_evaluations,
since remove_shortcuts now calls Order_eval.
Fixes golang/go#26495.

Give up the inlining expansion for strcmp/strncmp/memcmp on a target
where the type of the call has same or narrower presicion than unsigned
char.
Change char to unsigned char for strcmp/strncmp when expand them to
a sequence of byte comparisons.
Due to C standard section 7.24.4:
The sign of a nonzero value returned by the comparison functions memcmp,
strcmp, and strncmp is determined by the sign of the difference between
the values of the first pair of characters (both interpreted as unsigned
char) that differ in the objects being compared.
bootstraped and tested on both X86 and Aarch64. no regression.
