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. PR 81288/target * config/rs6000/rs6000.c (rs6000_rtx_costs): Do not handle TARGET_ISEL && !TARGET_MFCRF differently. Simplify code. From-SVN: r255188

If we have a negative condition we can use a literal 0 in the isel, instead of having to load it into a register. If the condition is from a comparison with an immediate we can change e.g. LT to LE and adjust the immediate, saving a li instruction. * config/rs6000/rs6000.md (<code><GPR:mode><GPR2:mode>2_isel): Change LT/GT/LTU/GTU to LE/GE/LEU/GEU where possible.
