> One drive-by request/question: have you done any measurements of the impact on debuggers? In other words, does it improve/make worse the time it takes them to load the debug data?
loading times for debuggers:
no gc-debuginfo case:
gdb 8.1 clang11 1,4G: loading time 56 sec used memory 2166872kb
lldb 8.0 clang11 1,4G: loading time 7.5 sec used memory 1508860kb
gc-debuginfo case:
gdb 8.1 clang11 783M: loading time 51 sec used memory 1741552kb
lldb 8.1 clang11 783M: loading time 4 sec used memory 842980kb
Overall result: gc-debuginfo makes loading time shorter and reduces memory usage for debuggers,
