Rope iterators: don't retain pointers when copied
Rope iterators sometimes contain pointers to an internal buffer
inside the iterator itself. When such an iterator is copied, the
copy incorrectly retains pointers to the original.
This patch takes the simple approach of not copying the cached
information when the internal buffer is being used, instead
requiring it to be recomputed when the copied iterator is
dereferenced. An alternative would be to adjust the pointers so
they refer to the buffer in the copy.

diagnostics: add line numbers to source (PR other/84889)
This patch adds a left margin to the lines of source (and annotations)
printed by diagnostic_show_locus, so that e.g. rather than:
test.c: In function 'test':
test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'?
return ptr->m_bar;
^~~~~
bar
we print:
test.c: In function 'test':
test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'?
12 | return ptr->m_bar;
| ^~~~~
| bar
Similarly, for a multiline case (in C++ this time), this:
bad-binary-ops.C: In function 'int test_2()':
bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't')
return (some_function ()
~~~~~~~~~~~~~~~~
+ some_other_function ());
^~~~~~~~~~~~~~~~~~~~~~~~
becomes:
bad-binary-ops.C: In function 'int test_2()':
bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't')
25 | return (some_function ()
| ~~~~~~~~~~~~~~~~
26 | + some_other_function ());
| ^~~~~~~~~~~~~~~~~~~~~~~~
I believe this slightly improves the readability of the output, in that it:
- distinguishes between the user's source code vs the annotation lines
that we're adding (the underlinings and fix-it hints here)
- shows the line numbers in another place (potentially helpful for
multiline diagnostics, where the user can see the line numbers directly,
rather than have to figure them out relative to the caret: in the 2nd
example, note how the diagnostic is reported at line 26, but the first
line printed is actually line 25)
I'm not sure that this is the precise format we want to go with [1], but
I think it's an improvement over the status quo, and we're in stage 1
of gcc 9, so there's plenty of time to shake out issues.
I've turned it on by default; it can be disabled via
-fno-diagnostics-show-line-numbers (it's also turned off in the testsuite, to
avoid breaking numerous existing test cases).

- maybe just "LL|" rather than "LL | "
- maybe ':' rather than '|'

Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting

The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it

This patch fixes the problem by testing for the presence of the _v2 versions,

[AArch64, Falkor] Switch to using Falkor-specific vector costs.
The adjusted vector costs give Falkor a reasonable boost in performance for FP
benchmarks (both CPU2017 and CPU2006) and doesn't change INT benchmarks that
much. There are some regressions that will be investigated as follow on work.
Numbers from the CI run:
CPU2017:
(R) 605.mcf_s: -1.8%
(R) 620.omnetpp_s: -2%
623.xalancbmk_s: 2%

FP mean: 0.70%
CPU2006:
(R) 429.mc: -5%

[aarch64] Adjust Falkor's sign extend reg+reg address cost
Adjust Falkor's register_sextend cost from 4 to 3. This fixes a testsuite

a sbfiz instruction rather than a load with sign extension.
