Paul Mackerras	c13c73f1ae	tests: Adjust header inclusions and Makefile.test This fixes the decrementer, illegal and sc tests to compile successfully with cross-compilers that don't provide unistd.h or string.h. Instead of those headers we include stddef.h. This also fixes tests/Makefile.test to do what one expects when CROSS_COMPILE is defined in the environment.

Michael Neuling	9d7df2d507	Add test cases for new exceptions and supervisor state This adds test cases for: - sc, illegals and decrementer exceptions - decrementer overflow - rfid - mt/mf sprg0/1 srr0/1 - mtdec - mtmsrd - sc It also adds these test cases to make check/check_light Signed-off-by: Michael Neuling <mikey@neuling.org>	6 years ago
Anton Blanchard	467630573c	Dump CTR, LR and CR on sim termination, and update our tests Right now our test cases fold the SPRs into the GPRs. That makes debugging fails more difficult than it needs to be, so print out the CTR, LR and CR. We still need to print the XER, but that is in two spots in microwatt and will take some more work. This also adds many instructions to the tests that we have added lately including overflow instructions, CR logicals and mt/mfxer. Signed-off-by: Anton Blanchard <anton@linux.ibm.com>	6 years ago
