Allow Search Command Of PTEs
When tracking down a bug in Win95, I found it useful to extend the
search command to search through the PTEs for a specific value. The
new syntax is
S addr addr # PTE
S addr L expr # PTE
where PTE can be any expression.
At the same time, I fixed a bug where a Page Fault during the display
of the searched for data caused a crash.
386SWAT.DOC Document new syntax.
386SWAT.GRM Document new syntax.
SWAT_MOD.INC Define new bit for PTE searching.
SWAT_HTX.ASM Document new syntax.
SWAT_OPR.ASM When returning from a trapped Page Fault, ensure that
ZF=1 in case the Page fault occurs on a REPNE
operation.
SWAT_SRC.ASM Change default SRC?MODE and SRC?MASK to PM with full
4GB range.
Define variables for searching PTEs.
Use PARSE_EXPR instead of PARSE_ATOM as appropriate
for greater generality.
Document new syntax.
Defer offset vs. mask checks to later so as to avoid
them for PTE searching.
Define actions for PTE searching.
