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. This leads to infinite recursion in CSE (see PR81288). This patch removes the too-high cost, also simplifying this code.
