The below makes devel/highway build on sparc64. I don't know what the
correct value for HWY_ARCH_MAX_BYTES would be. I tried 64 and 16 and
the tests look the same on the M3000.
99% tests passed, 3 tests failed out of 459
Total Test time (real) = 111.15 sec
The following tests FAILED:
391 - HwyMathTestGroup/HwyMathTest.TestAllExpm1/SCALAR (Subprocess
aborted)
405 - HwyMathHyperTestGroup/HwyMathHyperTest.TestAllAsinh/SCALAR
(Subprocess aborted)
407 - HwyMathHyperTestGroup/HwyMathHyperTest.TestAllSinh/SCALAR
(Subprocess aborted)
