Last change on this file since c2d2342 was c2d2342, checked in by Bruce Dubbs <bdubbs@…>, 13 months ago

Update test results for several packages.

Most of the changes were removing documentation of failed tests
that no longer fail.

152 On some combinations of kernel configuration and AMD processors
153 there may be more than 1100 failures in the gcc.target/i386/mpx
154 tests (which are designed to test the MPX option on recent
155 Intel processors). These can safely be ignored on AMD
156 processors. These tests will also fail on Intel processors if MPX support
157 is not enabled in the kernel even though it is present on the CPU.
