    • linemap_line_start: protect against location_t overflow (PR lto/88147) · a4553534 
      PR lto/88147 reports an assertion failure due to a bogus location_t value
when adding a line to a pre-existing line map, when there's a large
difference between the two line numbers.

For some "large differences", this leads to a location_t value that exceeds
LINE_MAP_MAX_LOCATION, in which case linemap_line_start returns 0.  This
isn't ideal, but at least should lead to safe degradation of location
information.

However, if the difference is very large, it's possible for the line
number offset (relative to the start of the map) to be sufficiently large
that overflow occurs when left-shifted by the column-bits, and hence
the check against the LINE_MAP_MAX_LOCATION limit fails, leading to
a seemingly-valid location_t value, but encoding the wrong location.  This
triggers the assertion failure:
  linemap_assert (SOURCE_LINE (map, r) == to_line);

The fix (thanks to Martin) is to check for overflow when determining
whether to reuse an existing map, and to not reuse it if it would occur.

    • Arm: Update tests after register allocation changes. (PR/target 88560) · e43a0139 
      
After the register allocator changes of r268705 we need to update a few tests
with new output.

In all cases the compiler is now generating the expected code, since the tests
are all float16 testcases using a hard-floar abi, we expect that actual fp16
instructions are used rather than using integer loads and stores.  Because of
we also save on some mov.f16s that were being emitted before to move between
the two.

The aapcs cases now match the f32 cases in using floating point operations.

    • [RS6000] No inline PLT for V4 bss-plt, implement -mno-pltseq · ff7fa488

    • PR libstdc++/89023 fix test that fails when <omp.h> not available · 271ad97b 
      Instead of a single test that only checks whether <regex> can be
included in Parallel Mode, add tests for each of C++11/C++14/C++17 that
check whether <bits/extc++.h> is compatible with _GLIBCXX_PARALLEL.
This increases the coverage to (almost) all headers.

If <omp.h> is not available then the tests will trivially pass, because
we don't care about compatibility with _GLIBCXX_PARALLEL in that case.
