// Note that parameterizing on these variables (and not other parameters) is

// too much, the gtest framework does not handle it well (increased overhead per
// test, huge amount of output to stdout, etc.).
//
// Also note that the test suites must be named with the architecture, e.g.,
// C, C_X, AVX2_X, ... The test suite that runs on Jenkins sometimes runs tests
// that cannot deal with intrinsics (e.g., the Valgrind tests on 32-bit x86
// binaries) and will disable tests using a filter like
// --gtest_filter=-:SSE4_1.*. If the test suites are not named this way, the
// testing infrastructure will not selectively filter them properly.
