6e70287776 Use generic/dot.c for DSDOT on ARMV5 and above 
The default arm/dot.c is less precise when used for DSDOT, as shown by utest

e207107150 Use generic/dot.c for DSDOT on z13 
The implementation in arm/dot.c has lower precision, as shown by the utest for dsdot.

7c1925acec Use .p2align instead of .align for compatibility on Sandybridge as well 2018-02-24 19:43:15 +01:00

2359c7c1a9 Use .p2align instead of .align for portability 
The OSX assembler apparently mishandles the argument to decimal .align, leading to a significant loss of performance 
as observed in #730, #901 and most recently #1470

e7366a4161 Restore the remaining utests (#1462) 
* Restore the remaining utests

* Try fork test on Cygwin and Linux only, it hangs on at least ARMv8/Android as well

* Use generic sswap/dswap kernels for NEHALEM 32bit to fix fault found by the restored swap utest

* Disable zdotu test for MS cl to work around runtime error -1073741819 on AppVeyor for now
(probably coding error in the initialization of the complex numbers or wrong choice of zdotu API)

The inline assembly modifies its input operands, so mark them as output to avoid surprises with optimization. Fixes #1292

any of the other Intel x86_64 microkernels.
