If it means that the interface to audit functions doesn't provide information about SSE register contents, then indeed any parts of the tests that rely on the interface providing such information can't be run for i386. But it should still be the case that audit functions for i386 can be ordinary C functions making use of SSE and AVX, and so clobbering any registers that are call-clobbered, without this interfering with function arguments or return values that are passed in such registers (where the i386 ABI involves use of SSE registers for argument passing or return, this should still work when the function being called is in a shared library). And so to the extent that the tests verify that such audit functions with incidental use of SSE or AVX work, they should be run for i386 - for example, I see nothing in tst-audit3 that should be inapplicable to i386. (If in fact such functions don't work, that's a separate bug.) -- You are receiving this mail because: You are on the CC list for the bug.
