Abstract
Systems and methods are provided for regular expression support in instrumentation languages using kernel-mode executable code. An example system includes a translator module that receives an input source code including a regular expression in a first source code language, wherein the translator module further determines a matching function in kernel-mode code language corresponding to the regular expression, and wherein the matching function corresponds to deterministic finite automaton. The system further includes a kernel module that processes at least one string using the matching function, wherein the matching function simulates state transitions of the deterministic finite automaton using the at least one string.
