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. 2017-11-29 Daniel Cederman <cederman@gaisler.com> gcc/ * config/sparc/sparc.c (fpop_insn_p): New function. (sparc_do_work_around_errata): Insert NOP instructions to prevent sequences that could trigger the TN-0012 errata for GR712RC.

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.

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. gcc/ChangeLog: * diagnostic-show-locus.c (layout::print_trailing_fixits): Handle m_x_offset.

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.

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

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 ?

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.
