Marcel Moolenaar	ad284e38a3	Wrap calls to memcpy(3) in a function called block_copy(). This way, ... and as long as we're not compiling with IPA, gcc(1) won't optimize the call away. The whole purpose of using memcpy(3) is to avoid misaligned loads and stores when we need to read or write the value in the unaligned memory location. But if gcc(1) optimizes the call to memcpy(3) away, it will typically introduce misaligned loads and stores. In this context that's not a good idea.	2005-01-28 02:58:32 +00:00
Marcel Moolenaar	c0604e27a8	Skip the register based postinc stores here and don't count them ... in the number of tests. This way we avoid skipped tests for non- existent memory access combinations. The number of tests dropped from 60 to 48.	2005-01-27 23:15:58 +00:00
Marcel Moolenaar	ced1bf58df	Make the local variables global so that the compiler cannot assume ... too much about them. This prevents certain peephole optimizations at -O that invalidate the tests.	2005-01-27 23:11:55 +00:00
Marcel Moolenaar	0335d35b09	Fix the unaligned store with post increment test: The misaligned pointer ... stopped pointing to the value the moment we wrote it due to the post increment. So, grab the value for comparison out of the data structure directly.	2005-01-27 22:46:15 +00:00
Marcel Moolenaar	baacc4acdf	Add tests for post increment. This bumps the number of tests up to ... 60. The postinc store tests currently fail (value mismatch). Hence the score as of this commit is 48 out of 60. Either the kernel or the tests need to be fixed.	2005-01-27 06:50:05 +00:00
Marcel Moolenaar	c5b5bf81c9	Regression test for unaligned loads and stores for short, int, long, ... float, double and long double types. No post-increment tests yet. All tests are skipped if the debug.unaligned_test sysctl variable cannot be set to 1.	2005-01-02 21:33:40 +00:00
