commandline used --
bash$ clang++ -Xclang -femit-debug-entry-values -O2 -ggdb test.cpp
For this case-- these Tags are not emitted
DW_TAG_call_site, DW_TAG_call_site_paramter ..
only DW_AT_GNU_all_call_sites attribute is present.
+ @Djorde DW_TAG_call_site are supported using late MIR approach, are the
new Call Site related development will be supported via MIR. or their will
be a frontend level debug metadata support will be added.
Thanks!
