// WHO WHEN WHAT\r
// --- ---------- ------------------------------------------------------------\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 Aug./2019 Added new functions to handle DWARF information, full filename fix\r
// JPM Mar./2020 Fix a random crash when reading the source lines information\r
+// JPM Aug./2020 Added a source code file date check when reading DWARF information\r
+// RG Jan./2021 Linux build fixes\r
//\r
\r
// To Do\r
// To use pointers instead of arrays usage\r
-// To keep sources text file intact wihtout QT/HTML transformation\r
