-Subject: [PATCH] arm: Fix LDRD register overlap [PR117675]
-
-The register indexed variants of LDRD have complex register overlap constraints
-which makes them hard to use without using output_move_double (which can't be
-used for atomics as it doesn't guarantee to emit atomic LDRD/STRD when required).
-Add a new predicate and constraint for plain LDRD/STRD with base or base+imm.
-This blocks register indexing and fixes PR117675.
-
-gcc:
-	PR target/117675
-	* config/arm/arm.cc (arm_ldrd_legitimate_address): New function.
-	* config/arm/arm-protos.h (arm_ldrd_legitimate_address): New prototype.
-	* config/arm/constraints.md: Add new Uo constraint.
-	* config/arm/predicates.md (arm_ldrd_memory_operand): Add new predicate.
-	* config/arm/sync.md (arm_atomic_loaddi2_ldrd): Use
-	arm_ldrd_memory_operand and Uo.
-
-gcc/testsuite:
-	PR target/117675
-	* gcc.target/arm/pr117675.c: Add new test.

-Subject: [PATCH] gcc: Fix c++: tweak for Wrange-loop-construct
-
-This commit updates the warning to use a check for "trivially constructible" instead of
-"trivially copyable." The original check was incorrect, as "trivially copyable" only applies
-to types that can be copied trivially, whereas "trivially constructible" is the correct check
-for types that can be trivially default-constructed.
-
-This change ensures the warning is more accurate and aligns with the proper type traits.
-
-LLVM accepted a similar fix:
-https://github.com/llvm/llvm-project/issues/47355

-The backport of the PR108900 fix to 14 branch broke building chromium
-because static_assert (__LINE__ == expected_line_number, ""); now triggers
-as the __LINE__ values are off by one.
-This isn't the case on the trunk and 15 branch because we've switched
-to 64-bit location_t and so one actually needs far longer header files
-to trigger it.

-contain (large) testcases in patch form which show on the 14 branch
-that the first one used to fail before the PR108900 backport and now
-works correctly, while the second one attempts to match the chromium
-behavior and it used to pass before the PR108900 backport and now it
-FAILs.
-The two testcases show rare problematic cases, because
-do_include_common -> parse_include -> check_eol -> check_eol_1 ->
-cpp_get_token_1 -> _cpp_lex_token -> _cpp_lex_direct -> linemap_line_start
-triggers there

-libcpp: Further fixes for incorrect line numbers in large files [PR120061]
-
-The backport of the PR108900 fix to 14 branch broke building chromium
-because static_assert (__LINE__ == expected_line_number, ""); now triggers
-as the __LINE__ values are off by one.
-This isn't the case on the trunk and 15 branch because we've switched
-to 64-bit location_t and so one actually needs far longer header files
-to trigger it.
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120061#c11
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120061#c12
-contain (large) testcases in patch form which show on the 14 branch
-that the first one used to fail before the PR108900 backport and now
-works correctly, while the second one attempts to match the chromium
-behavior and it used to pass before the PR108900 backport and now it
-FAILs.
-The two testcases show rare problematic cases, because
-do_include_common -> parse_include -> check_eol -> check_eol_1 ->
-cpp_get_token_1 -> _cpp_lex_token -> _cpp_lex_direct -> linemap_line_start
-triggers there
-      /* Allocate the new line_map.  However, if the current map only has a
-         single line we can sometimes just increase its column_bits instead. */
-      if (line_delta < 0
-          || last_line != ORDINARY_MAP_STARTING_LINE_NUMBER (map)
-          || SOURCE_COLUMN (map, highest) >= (1U << (column_bits - range_bits))
-          || ( /* We can't reuse the map if the line offset is sufficiently
-                  large to cause overflow when computing location_t values.  */
-              (to_line - ORDINARY_MAP_STARTING_LINE_NUMBER (map))
-              >= (((uint64_t) 1)
-                  << (CHAR_BIT * sizeof (linenum_type) - column_bits)))
-          || range_bits < map->m_range_bits)
-        map = linemap_check_ordinary
-                (const_cast <line_map *>
-                  (linemap_add (set, LC_RENAME,
-                                ORDINARY_MAP_IN_SYSTEM_HEADER_P (map),
-                                ORDINARY_MAP_FILE_NAME (map),
-                                to_line)));
-and so creates a new ordinary map on the line right after the
-(problematic) #include line.
-Now, in the spot that r14-11679-g8a884140c2bcb7 patched,
-pfile->line_table->highest_location in all 3 tests (also
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120061#c13
-) is before the decrement the start of the line after the #include line and so
-the decrement is really desirable in that case to put highest_location
-somewhere on the line where the #include actually is.
-But at the same time it is also undesirable, because if we do decrement it,
-then linemap_add LC_ENTER called from _cpp_do_file_change will then
-  /* Generate a start_location above the current highest_location.
-     If possible, make the low range bits be zero.  */
-  location_t start_location = set->highest_location + 1;
-  unsigned range_bits = 0;
-  if (start_location < LINE_MAP_MAX_LOCATION_WITH_COLS)
-    range_bits = set->default_range_bits;
-  start_location += (1 << range_bits) - 1;
-  start_location &=  ~((1 << range_bits) - 1);
-
-  linemap_assert (!LINEMAPS_ORDINARY_USED (set)
-                  || (start_location
-                      >= MAP_START_LOCATION (LINEMAPS_LAST_ORDINARY_MAP (set))));
-and we can end up with the new LC_ENTER ordinary map having the same
-start_location as the preceding LC_RENAME one.
-Next thing that happens is computation of included_from:
-  if (reason == LC_ENTER)
-    {
-      if (set->depth == 0)
-        map->included_from = 0;
-      else
-        /* The location of the end of the just-closed map.  */
-        map->included_from
-          = (((map[0].start_location - 1 - map[-1].start_location)
-              & ~((1 << map[-1].m_column_and_range_bits) - 1))
-             + map[-1].start_location);
-The normal case (e.g. with the testcase included at the start of this comment) is
-that map[-1] starts somewhere earlier and so map->included_from computation above
-nicely computes location_t which expands to the start of the #include line.
-With r14-11679 reverted, for #c11 as well as #c12
-map[0].start_location == map[-1].start_location above, and so it is
-((location_t) -1 & ~((1 << map[-1].m_column_and_range_bits) - 1)))
-+ map[-1].start_location,
-which happens to be start of the #include line.
-For #c11 map[0].start_location is 0x500003a0 and map[-1] has
-m_column_and_range_bits 7 and map[-2] has m_column_and_range_bits 12 and
-map[0].included_from is set to 0x50000320.
-For #c12 map[0].start_location is 0x606c0402 and map[-2].start_location is
-0x606c0400 and m_column_and_range_bits is 0 for all 3 maps.
-map[0].included_from is set to 0x606c0401.
-The last important part is again in linemap_add when doing LC_LEAVE:
-      /* (MAP - 1) points to the map we are leaving. The
-         map from which (MAP - 1) got included should be the map
-         that comes right before MAP in the same file.  */
-      from = linemap_included_from_linemap (set, map - 1);
-
-      /* A TO_FILE of NULL is special - we use the natural values.  */
-      if (to_file == NULL)
-        {
-          to_file = ORDINARY_MAP_FILE_NAME (from);
-          to_line = SOURCE_LINE (from, from[1].start_location);
-          sysp = ORDINARY_MAP_IN_SYSTEM_HEADER_P (from);
-        }
-Here it wants to compute the right to_line which ought to be the line after
-the #include directive.
-On the #c11 testcase that doesn't work correctly though, because
-map[-1].included_from is 0x50000320, from[0] for that is LC_ENTER with
-start_location 0x4080 and m_column_and_range_bits 12 but note that we've
-earlier computed map[-1].start_location + (-1 & 0xffffff80) and so only
-decreased by 7 bits, so to_line is still on the line with #include and not
-after it.  In the #c12 that doesn't happen, all the ordinary maps involved
-there had 0 m_column_and_range_bits and so this computes correct line.
-
-Below is a fix for the trunk including testcases using the
-location_overflow_plugin hack to simulate the bugs without needing huge
-files (in the 14 case it is just 330KB and almost 10MB, but in the 15
-case it would need to be far bigger).
-The pre- r15-9018 trunk has
-FAIL: gcc.dg/plugin/location-overflow-test-pr116047.c -fplugin=./location_overflow_plugin.so  scan-file static_assert[^\n\r]*6[^\n\r]*== 6
-and current trunk
-FAIL: gcc.dg/plugin/location-overflow-test-pr116047.c -fplugin=./location_overflow_plugin.so  scan-file static_assert[^\n\r]*6[^\n\r]*== 6
-FAIL: gcc.dg/plugin/location-overflow-test-pr120061.c -fplugin=./location_overflow_plugin.so  scan-file static_assert[^\n\r]*5[^\n\r]*== 5
-and with the patch everything PASSes.
-
-The patch reverts the r14-11679 change, because it is incorrect,
-we really need to decrement it even when crossing ordinary map
-boundaries, so that the location is not on the line after the #include
-line but somewhere on the #include line.  It also patches two spots
-in linemap_add mentioned above to make sure we get correct locations
-both in the included_from location_t when doing LC_ENTER (second
-line-map.cc hunk) and when doing LC_LEAVE to compute the right to_line
-(first line-map.cc hunk), both in presence of an added LC_RENAME
-with the same start_location as the following LC_ENTER (i.e. the
-problematic cases).
-The LC_ENTER hunk is mostly to ensure included_form location_t is
-at the start of the #include line (column 0), without it we can
-decrease include_from not enough and end up at some random column
-in the middle of the line, because it is masking away
-map[-1].m_column_and_range_bits bits even when in the end the resulting
-include_from location_t will be found in map[-2] map with perhaps
-different m_column_and_range_bits.  That alone doesn't fix the bug
-though.
-The more important is the LC_LEAVE hunk and the problem there is
-caused by linemap_line_start not actually doing
-    r = set->highest_line + (line_delta << map->m_column_and_range_bits);
-when adding a new map (the LC_RENAME one because we need to switch to
-different number of directly encoded ranges, or columns, etc.).
-So, in the original PR108900 case that
-  to_line = SOURCE_LINE (from, from[1].start_location);
-doesn't do the right thing, from there is the last < 0x50000000 map
-with m_column_and_range_bits 12, from[1] is the first one above it
-and map[-1].included_from is the correct location of column 0 on
-the #include line, but as the new LC_RENAME map has been created without
-actually increasing highest_location to be on the new line (we've just
-set to_line of the new LC_RENAME map to the correct line),
-  to_line = SOURCE_LINE (from, from[1].start_location);
-stays on the same source line.  I've tried to just replace that with
-  to_line = SOURCE_LINE (from, linemap_included_from (map - 1)) + 1;
-i.e. just find out the #include line from map[-1].included_from and
-add 1 to it, unfortunately that breaks the
-c-c++-common/cpp/line-4.c
-test where we expect to stay on the same 0 line for LC_LEAVE from
-<command line> and gcc.dg/cpp/trad/Wunused.c, gcc.dg/cpp/trad/builtins.c
-and c-c++-common/analyzer/named-constants-via-macros-traditional.c tests
-all with -traditional-cpp preprocessing where to_line is also off-by-one
-from the expected one.
-So, this patch instead conditionalizes it, uses the
-  to_line = SOURCE_LINE (from, linemap_included_from (map - 1)) + 1;
-way only if from[1] is a LC_RENAME map (rather than the usual
-LC_ENTER one), that should limit it to the problematic cases of when
-parse_include peeked after EOL and had to create LC_RENAME map with
-the same start_location as the LC_ENTER after it.
-
-Some further justification for the LC_ENTER hunk, using the
-https://gcc.gnu.org/pipermail/gcc-patches/2025-May/682774.html testcase
-(old is 14 before r14-11679, vanilla current 14 and new with the 14 patch)

-Subject: [PATCH] libstdc++: Fix std::chrono::tzdb to work with vanguard format
-
-I found some issues in the std::chrono::tzdb parser by testing the
-tzdata "vanguard" format, which uses new features that aren't enabled in
-the "main" and "rearguard" data formats.
-
-Since 2024a the keyword "minimum" is no longer valid for the FROM and TO
-fields in a Rule line, which means that "m" is now a valid abbreviation
-for "maximum". Previously we expected either "mi" or "ma". For backwards
-compatibility, a FROM field beginning with "mi" is still supported and
-is treated as 1900. The "maximum" keyword is only allowed in TO now,
-because it makes no sense in FROM. To support these changes the
-minmax_year and minmax_year2 classes for parsing FROM and TO are
-replaced with a single years_from_to class that reads both fields.
-
-The vanguard format makes use of %z in Zone FORMAT fields, which caused
-an exception to be thrown from ZoneInfo::set_abbrev because no % or /
-characters were expected when a Zone doesn't use a named Rule. The
-ZoneInfo::to(sys_info&) function now uses format_abbrev_str to replace
-any %z with the current offset. Although format_abbrev_str also checks
-for %s and STD/DST formats, those only make sense when a named Rule is
-in effect, so won't occur when ZoneInfo::to(sys_info&) is used.
-
-Since making this change on trunk, the tzdata-2024b release started
-using %z in the main format, not just vanguard. This makes a backport to
-release branches necessary (see PR 116657).
-
-This change also implements a feature that has always been missing from
-time_zone::_M_get_sys_info: finding the Rule that is active before the
-specified time point, so that we can correctly handle %s in the FORMAT
-for the first new sys_info that gets created. This requires implementing
-a poorly documented feature of zic, to get the LETTERS field from a
-later transition, as described at
-https://mm.icann.org/pipermail/tz/2024-April/058891.html
-In order for this to work we need to be able to distinguish an empty
-letters field (as used by CE%sT where the variable part is either empty
-or "S") from "the letters field is not known for this transition". The
-tzdata file uses "-" for an empty letters field, which libstdc++ was
-previously replacing with "" when the Rule was parsed. Instead, we now
-preserve the "-" in the Rule object, so that "" can be used for the case
-where we don't know the letters (and so need to decide it).
-
-(cherry picked from commit 0ca8d56f2085715f27ee536c6c344bc47af49cdd)
