MPS issue job001543

TitleMPS mpsicv (test) on OS X does not use reg&stack scanner.
Assigned userRichard Kistruck
DescriptionMPS 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.
