Paul Mackerras	0a95e4bfdd	tests: Put an attn instruction at 0x700 This puts an attn instruction at offset 0x700 in each of the tests so that the test will terminate if a program interrupt is taken. This means that we can implement the tw instruction to cause a program interrupt. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	6 years ago
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
