| Description | MPS mpsicv (test) on OS X does not use reg&stack scanner. MPS mpsicv coverage test source has ifndef CONFIG_PF_XCPPGC. [RHSK 2006-12-11] This means that on XCPPGC (OS X on PPC) is not testing the reg&stack scanner, even though this now exists (ssxcpp.s). |
| Analysis | [RHSK 2006-12-11] Should remove the ifndef and check it's ok. Or perhaps change it to apply to OS X on Intel? See job001544. 2007-03-01 DRJ: Actually that's CONFIG_PF_XCPPGC not MPS_PF_XCPPGC. Our build sytem doesn't define CONFIG_PF_XCPPGC (speculation: Maybe Global Graphics define this?). So I believe that the reg&stack scanner in ssxcpp.s was in fact being used. Further confirmed by adding a PRINT to the code. I removed the #if. In change 161466. xcppgc/ci/mpsicv now fails with an assertion when running under Rosetta. That's a Rosetta bug, see job001634 . It should be fine on real silicon. |
