-// JPM 12/03/2016 Created this file\r
-// JPM 12/03/2016 DWARF format support\r
+// JPM Dec./2016 Created this file, and added the DWARF format support\r
// JPM Sept./2018 Added LEB128 decoding features, and improve the DWARF parsing information\r
+// JPM Oct./2018 Improve the DWARF parsing information, and the source file text reading; support the used source lines from DWARF structure, and the search paths for the files\r
+// JPM Mar./2020 Fix a random crash when reading the source lines information\r
//\r
\r
// To Do\r
// To use pointers instead of arrays usage\r
