+gcc testsuite tweaks for mips/OE
+
+Disable loongson-mmi runtine, qemu doesn't appear to fully support them even if some
+of the instruction decoding is there.
+
+Also disable MSA mips runtime extensions. For some reason qemu appears to accept the test
+code when it shouldn't. Our selected MIPS cpu for QEMU doesn't support them.
+
+MIPS is unusual in the gcc testsuite as it uses EFFECTIVE_TARGETS and loops
+multiple times through the vector testsuite. In the case of the two above, we can
+compile/link them but not run them. Even with the runtime disabled, if the code
+marks it as a runtime test, it will elevate itself to that. Setting the default
+target to compile therefore isn't enough.
+
+Therefore add code to downgrade runtime tests to link tests if the hardware
+support isn't there to run them. This avoids thousands of test failures. To do
+this we have to hook downgrade code into the main test runner.
+
+Enable that downgrading for other cases where hardware to run vector extensions is
+unavailable to remove test failures on other architectures too.
+
+Also, for gcc.target tests, add checks on wheter loongson or msa code can
+be run before trying that, allowing downgrading of tests there to work too.
+
+Upstream-Status: Pending
+[Parts of the patch may be able to be split off and acceptable to upstream with
+discussion. Need to investigate why qemu-user passes the 'bad' instructions']
