Subject: [PATCH 07/12] [gdb/symtab] Fix line number of static const class
|
|
member
|
|
|
|
Since commit 6d263fe46e0 ("Avoid bad breakpoints with --gc-sections"), there
|
|
was a silent regression on openSUSE Leap 15.4 for test-case
|
|
gdb.cp/m-static.exp, from:
|
|
...
|
|
(gdb) info variable everywhere^M
|
|
All variables matching regular expression "everywhere":^M
|
|
^M
|
|
File /home/vries/tmp.local-remote-host-native/m-static.h:^M
|
|
8: const int gnu_obj_4::everywhere;^M
|
|
(gdb)
|
|
...
|
|
to:
|
|
...
|
|
(gdb) info variable everywhere^M
|
|
All variables matching regular expression "everywhere":^M
|
|
^M
|
|
File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
|
|
8: const int gnu_obj_4::everywhere;^M
|
|
^M
|

|
|
Another regression was found due to that commit, and it was fixed in commit
|
|
99d679e7b30 ("[gdb/symtab] Fix "file index out of range" complaint") by
|
|
limiting the scope of the fix in the original commit.
|
|
|
|
Fix this regression by yet further limiting the scope of that fix, making sure
|
|
that this bit in dwarf_decode_lines is executed again for m-static1.cc:
|
|
...
|
|
/* Make sure a symtab is created for every file, even files
|
|
which contain only variables (i.e. no code with associated
|
|
line numbers). */
|
|
...
|
|
|
|
Tested on x86_64-linux.
