Hi, the minimum version of gtest that we tested with is 1.8.0, which was launched in 2016. I just checked 1.7 and I don't see the templated TestParam version, which...

This currently fails in a bunch of `HwyMathTestGroup` tests (more failures for gcc i686 than for x86_64)

So, the compilation takes quite a while because it compiles for all 4 targets. The other two clang builders compile only scalar (1m) vs these builders that compile all (5m)....

@jan-wassenberg HwyMathTestGroup/HwyMathTest.TestAllAcos segfaults here for `x86_64`, but I don't see any log output about it. Maybe it would help to use EXPECT_EQ and similar functions instead of HWY_ASSERT for tests.

@jan-wassenberg I rebased it and SortTestGroup/SortTest.TestAllReverse/AVX2 is now failing, and also clang-5

We need to first figure our what use cases we want to support here. "high-level" can mean different things for different people. Some use cases we identified when discussing this...

I think that the default order (left-to-right, top to bottom) is better from a decoder performance point of view, so that's a consideration too. If progressive decoding is not "needed"...

I'm not talking about the file size penalty, but the decoding performance penalty (CPU/RAM). If the groups come in the default order (or if we decode them in the default...
