d568f0b6db Clarify source of tm.texi to copy for GFDL grant
When tm.texi.in is updated in the source tree, the following message
gets displayed:

Verify that you have permission to grant a GFDL license for all
new text in tm.texi, then copy it to <gcc src dir>/gcc/doc/tm.texi.

Having been myself and some colleagues confused several time by that
message as to what tm.texi to copy, I think it would be clearer to
indicate the absolute path for the source as well. This patch achieves
that.

b8d5e148f6 Allow inner-loop reductions with variable-length vectors
While working on PR 86871, I noticed we were being overly restrictive
when handling variable-length vectors.  For:

  for (i : ...)
    {
      res = ...;
      for (j : ...)
        res op= ...;
      a[i] = res;
    }

we don't need a reduction operation (although we do for double
reductions like:

  res = ...;
  for (i : ...)
    for (j : ...)
      res op= ...;
  a[i] = res;

which must still be rejected).

56b61d7fc4 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).

[1] Some possible variants:
  - maybe just "LL|" rather than "LL | "
  - maybe ':' rather than '|'
  - maybe we should have some leading indentation, to better split up
    the diagnostics visually via the left-hand column
  - etc

3dec9a89d4 Restore flow_bb_inside_loop_p tests (PR 86858)
The series to remove vinfo_for_stmt also removed tests of
flow_bb_inside_loop_p if the call was simply testing whether the
statement was in the vectorisation region.  I'd tried to keep calls
that were testing whether the statement was in a particular loop
(inner or outer), but messed up in vect_is_simple_reduction and
removed calls that were actually needed.  This patch restores them.

I double-checked the other removed calls and I think these are
the only ones affected.

0b06c9a6da S/390: Fix PR84332 ICE with stack clash protection
Our implementation of the stack probe requires the probe interval to
be used as displacement in an address operand.  The maximum probe
interval currently is 64k.  This would exceed short displacements.
Trim that value down to 4k if that happens.  This might result in too
many probes being generated only on the oldest supported machine level
z900.

8e09a12f01 [libgomp, nvptx] Fall back to cuLinkAddData/cuLinkCreate if _v2 not found
Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting
version 5.5.  In version 6.5, they are remapped onto _v2 versions.

The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it
won't work with a cuda driver with driver api version lower than 6.5.

This patch fixes the problem by testing for the presence of the _v2 versions,
and falling back to the original versions in case of absence of the _v2
versions.

Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and
without --without-cuda-driver.

cedd9bd016 [libgomp, nvptx] Allow cuGetErrorString to be NULL
Cuda driver api function cuGetErrorString is available in version 6.0 and
higher.

Currently, when the driver that is used does not contain this function, the
libgomp nvptx plugin will not build (PLUGIN_NVPTX_DYNAMIC == 0) or run
(PLUGIN_NVPTX_DYNAMIC == 1).

This patch fixes this problem by testing for the presence of the function, and
handling absence.

CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR is defined in cuda driver
api version 6.0 and higher.

Currently nvptx_open_device uses a hard-coded constant instead.

This patch fixes that by:
- defining CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR to the hardcoded
  constant at toplevel, if not present in cuda.h, and
- using CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR in nvptx_open_device

TARGET_CPU_ZARCH is always true.  As a side-effect, branch splitting

9be4d77249 libgo: uncomment trace.Stop() call in testing package
Fix up the testing package to insure that execution traces
    work properly (e.g. "-test.trace=<XXX>" command line option). The
    call to stop tracing and emit the output file was stubbed out.

4663b943c6 [AArch64] Fix -mlow-precision-div (PR 86838)
The "@" handling broke -mlow-precision-div, because the scalar forms of
the instruction were provided by a pattern that also provided FRECPX
(and so were parameterised on an unspec code as well as a mode),
while the SIMD versions had a dedicated FRECPE pattern.  This patch
moves the scalar FRECPE handling to the SIMD pattern too (as for FRECPS)
and uses a separate pattern for FRECPX.

The convention in aarch64-simd-builtins.def seemed to be to add
comments only if the mapping wasn't obvious (i.e. not just sticking
"aarch64_" on the beginning and "<mode>" on the end), so the patch
deletes the reference to the combined pattern instead of rewording it.

There didn't seem to be any coverage of -mlow-precision-div in the
testsuite, so the patch adds some tests for it.
