re PR preprocessor/78680 (ICE in get_substring_ranges_for_loc, at input.c:1398)
Fix for PR preprocessor/78680
PR preprocessor/78680 identifies a crash when attempting to issue
a -Wformat warning, where the format string includes a string token
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.

However this is no longer true on a number of levels. A vanilla Darwin system has

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

runtime: allocate _panic struct on heap
The gc library allocates a _panic struct on the stack. This does not
work for gccgo, because when a deferred function recovers the panic we
unwind the stack up to that point so that returning from the function
will work correctly.
Allocating on the stack fine if the panic is not recovered, and it
works fine if the panic is recovered by a function that
returns. However, it fails if the panic is recovered by a function
that itself panics, and if that second panic is then recovered by a
function higher up on the stack. When we unwind the stack to that
second panic, the g will wind up pointing at a panic farther down on
the stack. Even then everything will often work fine, except when the
deferred function catching the second panic makes a bunch of calls
that use stack space before returning. In that case the code can
overwrite the panic struct, which will then cause disaster when we
remove the struct from the linked list, as the link field will be
garbage. This case is rare enough that all the x86 tests were passing,
but there was a failure on ppc64le.
Before https://golang.org/cl/33414 we allocated the panic struct on
the heap, so go back to doing that again.
Fixes golang/go#18228.
