elf mapper

Replaces address occurrences matching 0x[0-9a-zA-Z]{4} by labels as shown by readelf -a. This usefull when generating a .dot graph where addresses should be replaced by labels. In case of multiple labels, the address is replaced by a list: {labe1, label2, labeln}.

Usage

java -jar <mapper> <labelsFile> <fileToReplaceAddresses>

Writes the translated file to pretty-fileToReplaceAddresses.

Compile

mvn clean assembly:single

Run

readelf -a > elfDump.txt
java -jar ./target/elf-mapper-0.0.2-SNAPSHOT-jar-with-dependencies.jar elfDump.txt fileToReplaceAddresses.txt

Example

A .dot file snippet with replaced addresses.
