47c72733ab [SPARC] Errata workaround for GRLIB-TN-0010
This patch provides a workaround for the errata described in GRLIB-TN-0010.

If the workaround is enabled it will:

 * Insert a NOP between load instruction and atomic
   instruction (swap, ldstub, casa).

 * Insert a NOP at branch target if load in delay slot
   and atomic instruction at branch target.

It is applicable to UT700.

dcacda0cc1 [SPARC] Errata workaround for GRLIB-TN-0012
This patch provides a workaround for the errata described in GRLIB-TN-0012.

If the workaround is enabled it will:

 * Prevent any floating-point operation from being placed in the
   delay slot of an annulled integer branch.

 * Place a NOP at the branch target of an integer branch if it is
   a floating-point operation or a floating-point branch.

It is applicable to GR712RC.

e69a816d8f [AArch64] Fix ICE due to store_pair_lanes
The recently added store_pair_lanes causes ICEs in output_operand.
This is due to aarch64_classify_address treating it like a 128-bit STR
rather than a STP.  The valid immediate offsets don't fully overlap,
causing it to return false.  Eg. offset 264 is a valid 8-byte STP offset
but not a valid 16-byte STR offset since it isn't a multiple of 16.

The original instruction isn't passed in the printing code, so the context
is unclear.  The solution is to add a new operand formatting specifier
which is used for LDP/STP instructions like this.  This, like the Uml
constraint that applies to store_pair_lanes, uses PARALLEL when calling
aarch64_classify_address so that it knows it is an STP.
Also add the 'z' specifier for future use by load/store pair instructions.

    gcc/
	* config/aarch64/aarch64.c (aarch64_print_operand): Add new
	cases for printing LDP/STP memory addresses.
	(aarch64_print_address_internal): Renamed from

	(aarch64_print_operand_address): Indirect to
	aarch64_print_address_internal.

64ea27f0d2 Handle very long lines when printing fix-it hints
When fixing PR c/82050 I noticed a bug in how we print fix-it hints
for very long lines: we weren't taking into account the x-offset for
the line when printing the fix-it hint.

This could lead to output where instead of printing:

foo.c:14:3944: error: etc
  = foo.field
        ^~~~~
        replacement

where the lines have been offset to start printing at about column 3900,
the "replacement" line was erroneously *not* offset, and was thus
prefixed by thousands of spaces, leading to large whitespace gaps in
the output, and the replacement failing to line up with the source to be
replaced.

Fixed thusly.

67c24a8bd6 PR 53796 Improve INQUIRE(RECL=...) handling
The current F2018 draft (N2137) specifies behavior of the RECL=
specifier in the INQUIRE statement, where it previously was left as
undefined. Namely:

- If the unit is not connected, RECL= should be given the value -1.
- If the unit is connected with stream access, RECL= should be given
  the value -2.

Further, as PR 53796 describes, the handling of RECL= is poor in other
ways as well. When the recl is set to the maximum possible
(GFC_INTEGER_8_HUGE / LLONG_MAX), which it does by default except for
preconnected units, and when INQUIRE(RECL=) is used with a 4 byte
integer, the value is truncated and the 4 byte value is thus
-1. Fixing this to generate an error is a lot of work, as currently
the truncation is done by the frontend, the library sees only an 8
byte value with no indication that the frontend is going to copy it to
a 4 byte one. Instead, this patch does a bit twiddling trick such that
the truncated 4 byte value is GFC_INTEGER_4_HUGE while still being
0.99999999 * GFC_INTEGER_8_HUGE which is large enough for all
practical purposes.

Finally, the patch removes GFORTRAN_DEFAULT_RECL which was used only
for preconnected units, and instead uses the same approach as describe
above.

Regtested on x86_64-pc-linux-gnu, Ok for trunk.

6df8934f6a Reject fix-it hints for various awkward boundary cases (PR c/82050)
PR c/82050 reports a failed assertion deep within diagnostic_show_locus's
code for printing fix-it hints.

The root cause is a fix-it hint suggesting a textual replacement,
where the affected column numbers straddle the LINE_MAP_MAX_COLUMN_NUMBER
boundary, so that the start of the range has a column number, but the
end of the range doesn't.

The fix is to verify that the column numbers are sane when adding fix-it
hints to a rich_location, rejecting fix-it hints where they are not.

	PR c/82050
	* include/line-map.h (LINE_MAP_MAX_COLUMN_NUMBER): Move here.

1be49a38e4 [Patch AArch64] Fixup floating point division with -march=armv8-a+nosimd
The canonical examples is :

    double
    foo (double x, double y)
      {
        return x / y;
      }

    with -march=armv8-a+nosimd

generates a function that calls __divdf3. Ofcourse on AArch64 we don't
have any software floating point and this causes issues.

There is also a problem in +nosimd that has existed since the dawn of
time in the port with respect to long doubles (128 bit floating
point), here the ABI and the compiler expect the presence of the SIMD
unit as these parameters are passed in the vector registers. Thus
while +nosimd tries to prevent the use of SIMD instructions in the
compile we don't get this right as we end up using ldr qN / str qN
instructions and even there I think things go wrong in a simple
example that I tried.

Is that sufficient to consider marking +nosimd as deprecated in GCC-8
and remove this in a future release ?

That is not a subject for this patch but something separate but I
would like to put this into trunk and the release
branches. Bootstrapped and regression tested on my aarch64 desktop.

Ok ?

b8adcbd923 rs6000: Improve comparison rtx_cost (PR81288)
The current rs6000 rtx_cost for comparisons against 0 is very high if
TARGET_ISEL && !TARGET_MFCRF, much higher than for reg-reg comparisons,
much higher than a load of 0 and such a reg-reg-comparison.  This leads
to infinite recursion in CSE (see PR81288).

This patch removes the too-high cost, also simplifying this code.


	PR 81288/target
	* config/rs6000/rs6000.c (rs6000_rtx_costs): Do not handle
	TARGET_ISEL && !TARGET_MFCRF differently.  Simplify code.
