Address Map Modifier Differences Between adb and MDB
The adb commands to modify segments of the virtual
address map and object file map are not present in MDB. Specifically, the
/m, /*m, ?m, and
?*m format specifiers are not recognized or supported
by MDB. These specifiers were used to manually modify the valid
addressable range of the current object and core files. MDB properly
recognizes the addressable range of such files automatically, and updates
the ranges when a live process is being debugged, so these commands are no
longer necessary.
