split across multiple physical source lines via backslash-continued
lines.

The issue is that libcpp is generating bogus range information for
such tokens.

For example, in:

void fn1() {
  __builtin_printf("\
     %ld.\n\
        2\n"); };

the range of the string token is printed as:

   __builtin_printf("\
                    ^~

whereas the range ought to be:

  __builtin_printf("\
                   ^~
     %ld.\n\
     ~~~~~~~
        2\n"); };
        ~~~~

The root cause is that the line notes expressing the update
of the buffer in lex.c aren't yet updated when the end-point of
the token is computed

3095     tok_range.m_finish
3096       = linemap_position_for_column (pfile->line_table,
3097      CPP_BUF_COLUMN (buffer, buffer->cur));

so that the physical line is still regarded as that of the start
of the token, and, where CPP_BUF_COLUMN uses (BUF)->line_base,
line_base is still the location of the first physical line in the
and hence the column information is too large (as if it were the
offset in the *logical* line).

(the printed range is somewhat misleading; the actual buggy range
extends beyond the "\ in the line, but within diagnostic-show-locus.c
layout::print_annotation_line only prints up to the xbound set by
layout::print_source_line and so truncates most of the buggy range).

The fix is to ensure that line notes are handled before calculating
the end-point of the token range.

This leads to the range for the string token being correctly
computed, as:

  __builtin_printf("\
                   ^~
     %ld.\n\
     ~~~~~~~
        2\n"); };
        ~~~~

and this leads to get_substring_ranges_for_loc failing gracefully,
rather than crashing.

[Darwin, configury] No longer expect to find cross-target headers on the host.

Earlier Darwin (esp. Darwin8 and Darwin9) had FAT libraries and suitable header
installations in /usr/include such that one could build a cross-toolchain
(including cross-arch) using a common sysroot (including / for “current” version).

However this is no longer true on a number of levels.  A vanilla Darwin system has
no headers installed in /usr and it's certainly not appropriate to try and find

This patch fixes an issue in aarch64_classify_address.

This patch fixes an issue in aarch64_classify_address.  TImode and TFmode
can either use a 64-bit LDP/STP or 128-bit LDR/STR.  The addressing mode
must be carefully modelled as the intersection of both.  This is done for
the immediate offsets, however load_store_pair_p must be set as well to
avoid LDP with a PC-relative address if aarch64_pcrelative_literal_loads
is true.
