C++17 says to use std::uncaught_exceptions() here instead of std::uncaught_exception() but since we only care whether the result is non-zero (and we aren't planning to remove the deprecated version) we can just keep using std::uncaught_exception() and suppress the warning. * include/std/ostream (basic_ostream::sentry::~sentry): Suppress deprecation warnings for using uncaught_exception(). git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@263593 138bc75d-0d04-0410-961f-82ee72b054a4
This allows copy_blkmode_to_reg to perform larger copies when it is safe to do so by calculating the bitsize per iteration doing the maximum copy allowed that does not read more than the amount of bits left to copy. Strictly speaking, this copying is only done if: 1. the target supports fast unaligned access 2. no padding is being used. This should avoid the issues of the first patch (PR85123) but still work for targets that are safe to do so.

PR c++/70693 reports a crash within -Wmisleading-indentation in get_visual_column, reading past the end of a source line. The issue occurs due to a stray carriage return aka '\r' aka ^M, occurring towards the end of line 35 of attachment 38289 - but not at the end itself. This carriage return confuses our line numbering: from that point in the file, the lexer (and thus location_t values) use line numbers that are one larger than those seen by input.c, "cat -n" and emacs. This discrepancy between the lexer's line numbering and input.c's line numbering leads to an out-of-range read in get_visual_column (trying to read column 8, to locate the first non-whitespace on the line containing "break;", but finding the next line, which is only 4 characters long). This patch fixes the ICE by adding a range check to get_visual_column before accessing the input.c line buffer. This is arguably papering over the root cause, but there are presumably other ways of triggering such an out-of-range read by writing to the source file after the lexer but before -Wmisleading-indentation, and we ought to be not ICE in the face of that. gcc/c-family/ChangeLog: PR c++/70693 * c-common.c (selftest::c_family_tests): Call selftest::c_indentation_c_tests. * c-common.h (selftest::c_indentation_c_tests): New decl. * c-indentation.c: Include "selftest.h".

This moves what is currently the default of the length attribute to the only branch instruction patterns where it applies, namely, the B-form instructions. It was used for the "jump" instruction as well before, but that is an I-form instruction and always has length 4. * config/rs6000/rs6000.md (length): Always define as const_int 4.

There were many insns that set "length 4" explicitly while that does not make anything clearer to the reader. So, simplify the code. * config/rs6000/altivec.md: Don't set length attribute to the default value. * config/rs6000/darwin.md: Ditto. * config/rs6000/dfp.md: Ditto. * config/rs6000/htm.md: Ditto. * config/rs6000/rs6000.md: Ditto. * config/rs6000/sync.md: Ditto. * config/rs6000/vsx.md: Ditto. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@263603 138bc75d-0d04-0410-961f-82ee72b054a4
There are some patterns that recognise the parallel of an add and a compare, and split it back to the same two insns. This apparently helped RIOS machines before RTL scheduling existed? Either way, it isn't helpful anymore, and even hurts a tiny bit. So, delete it. * config/rs6000/rs6000.md (two unnamed define_insn and define_split): Delete. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@263604 138bc75d-0d04-0410-961f-82ee72b054a4
This commit slightly tweaks line-insertion fix-it hints, so that
with line-numbering, rather than e.g.:
99 | x = a;
|+ break;
110 | case 'b':
| ^~~~~~~~
we fill the margin with "+":
99 | x = a;
+++ |+ break;
110 | case 'b':
| ^~~~~~~~
to emphasize that this is a suggested new line, rather than the user's
source.

"margin_char" parameter, defaulting to space. Use it in place

Without this patch, the "line span" markers and the line numbering
interacted badly, leading to stray copies of the line-span markers
appearing as prefixes on the first source line in a span:

This patch converts dump_print and dump_printf_loc from using
printf (and thus ATTRIBUTE_PRINTF) to using a new pretty-printer
based on pp_format, which supports formatting middle-end types.
In particular, the following codes are implemented (in addition
to the standard pretty_printer ones):
%E: gimple *:
Equivalent to: dump_gimple_expr (MSG_*, TDF_SLIM, stmt, 0)
%G: gimple *:
Equivalent to: dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)
%T: tree:
Equivalent to: dump_generic_expr (MSG_*, arg, TDF_SLIM).
Hence it becomes possible to convert e.g.:
if (dump_enabled_p ())
{
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, " and ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, nunits_vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, "\n");
}
into a one-liner:
if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, %T and %T\n",
vectype, nunits_vectype);
Unlike regular pretty-printers, this one captures optinfo_item
instances for the formatted chunks as appropriate, so that when
written out to a JSON optimization record, the relevant parts of
the message are labelled by type, and by source location (so that
e.g. %G is entirely equivalent to using dump_gimple_stmt).
dump_printf and dump_printf_loc become marked with
ATTRIBUTE_GCC_DUMP_PRINTF, which the patch also implements.

Previously the logic that turned "a/b/c/../.." into "a/" failed to preserve an empty path at the end of the iteration sequence, as required by the trailing slash.

This is the gofrontend version of https://golang.org/cl/91796.
This is part of that CL, just the compiler change and required runtime
changes, in preparation for updating libgo to 1.11.
Relevant part of original CL description:
The hmap field in the maptype is only used by the runtime to check the sizes of
the hmap structure created by the compiler and runtime agree.
Comments are already present about the hmap structure definitions in the
compiler and runtime needing to be in sync.
