10 | // JPM 08/31/2018 Created this file | |
11 | // JPM 09/12/2018 Added a status bar and better status report | |
12 | // JPM 10/20/2018 Added the return address information in the call stack | |
13 | // JPM 08/09/2019 Prevent crash in case of call stack is out of range | |
14 | // JPM 03/16/2020 Modified the layout window and added source filename from the called source line | |
0718b3f2 JPM |
15 | |
16 | // STILL TO DO: | |
2b91c435 | 17 | // To set the information display at the right |
8b11a1b0 JPM |
18 | // To use DWARF frame information? |
19 | // To check if call stack pointer is used (DWARF information?) | |
