2017-11-28[Patch AArch64] Fixup floating point division with -march=armv8-a+nosimdRamana Radhakrishnan3-1/+10
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 ?

2017-11-28rs6000: Improve comparison rtx_cost (PR81288)Segher Boessenkool2-17/+12
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.

2017-11-24Factor out division by squaresJackson Woodruff6-30/+289
This patch implements the some of the division optimizations discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026. The division reciprocal optimization now handles divisions by squares: x / (y * y) -> x * (1 / y) * (1 / y) This requires at least one more division by y before it triggers - the 3 divisions of (1/ y) are then CSEd into a single division. Overall this changes 1 division into 1 multiply, which is generally much faster. 2017-11-24 Jackson Woodruff <jackson.woodruff@arm.com> gcc/ PR tree-optimization/71026 * tree-ssa-math-opts (is_division_by_square, is_square_of): New.
