Török Edvin	c47be26412	matcher-ac optimization: ... eliminate the IS_LEAF branch from the scanner: - concatenate the leaf's list with the failtarget's list - copy the trans pointer from the failtarget - make sure we only free the trans table once in ac_free (because we have more than 1 ->trans pointers that points to same place now) This results in ~5% speed improvement.	14 years ago
Török Edvin	e7fbb6a7d9	matcher-ac: optimize the not-taken case ... This generates more efficient code for the trie traversing loop, using registers instead of stack locations for the variables.	14 years ago

Török Edvin	ab89360583	Support for macros in logical subsignatures (bb #164). ... In the LDB there is (one or more) special subsignature ${min-max}MACROID$, which means: must match any signature from group MACROID (for current filetype), and the match must occur at a distance of min-max from the start(!) of the previous logical subsignature match. It also has the sideeffect of making the previous subsignature considered a match only if both that and the macro matches. The offset of first match for the previous logical subsig will be the offset where the {min-max} distance is satisfied. The macro logical subsignature will have a count of 0 (if it didn't match together with the previous subsig), or a count of 1 if it did. The matches can occur anywhere (even in different ac scan buffers), since I don't call cli_ac_scanbuff I just use the offset of first match (which we have for the bytecode anyway). There can be at most 32 macro groups, signatures are added to a macro group by using $MACROID$ as offset. For example pdb entries could be converted to PDB:3:$0:<hexsig of domainname> if we assign macro id 0 to PDB (and we can assign 31 more macro ids to whatever). Example: test.ldb: TestMacro;Target:0;0&1;616161;${3-4}12$ test.ndb: D:0:$12:6262 D:0:$12:6363 D:0:$11:6262 test.dat: aaaaxccdd test-nomatch.dat: aaaaxxxccdd	16 years ago
