Description Tom de Vries 2021-02-08 13:32:16 UTC

[ Not a duplicate of PR24756, that one is related to split dwarf.  There will be overlap though. ]

$ clang -gdwarf-5 ../src/testsuite/dwz.tests/hello.c 
$ cp a.out 1; ./dwz 1
./dwz: 1: Unknown debugging section .debug_addr

Also note that there are two new location operations DW_OP_addrx and DW_OP_constx that can reference the .debug_addr section index.

Note that patch has been integrated and is in release but doesn't handle .debug_addr.
