Bug ID: 25655
Summary: Language is not auto/ada in main ada function for exec
without debug info
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Consider the executable produced by gdb.ada/minsyms.exp: foo_qb07_057, an
executable build without debug info (well, for the source files, as usual there
will be debug info for the linked-in libraries and startup files for openSUSE).
When running to main, the language changes from auto/ada to auto/c:
...
$ gdb -batch -iex "set verbose on" foo_qb07_057 -ex "show language" -ex start
Reading symbols from foo_qb07_057...
The current source language is "auto; currently ada".
Temporary breakpoint 1 at 0x401fbc
Reading symbols from /lib64/ld-linux-x86-64.so.2...
Reading symbols from
/usr/lib/debug/lib64/ld-2.26.so-2.26-lp151.18.7.x86_64.debug...
Reading symbols from system-supplied DSO at 0x7ffff7ffa000...
(No debugging symbols found in system-supplied DSO at 0x7ffff7ffa000)
Reading in symbols for rtld.c...
Reading symbols from /lib64/libc.so.6...
Reading symbols from
/usr/lib/debug/lib64/libc-2.26.so-2.26-lp151.18.7.x86_64.debug...
Temporary breakpoint 1, 0x0000000000401fbc in foo_qb07_057 ()
Current language: auto
The current source language is "auto; currently c".
...
After removing --with-separate-debug-dir=/usr/lib/debug from my configure
flags, such that package debug info is not found, I have instead:
...
$ gdb -batch -iex "set verbose on" foo_qb07_057 -ex "show language" -ex start
-ex "show language"
Reading symbols from foo_qb07_057...
The current source language is "auto; currently ada".
Temporary breakpoint 1 at 0x401fbc
Reading symbols from /lib64/ld-linux-x86-64.so.2...
(No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
Reading symbols from system-supplied DSO at 0x7ffff7ffa000...
(No debugging symbols found in system-supplied DSO at 0x7ffff7ffa000)
Reading symbols from /lib64/libc.so.6...
(No debugging symbols found in /lib64/libc.so.6)
Temporary breakpoint 1, 0x0000000000401fbc in foo_qb07_057 ()
The current source language is "auto; currently ada".
...
Now the language just remains ada.
It seems we should do better in the first case.

Classifying this as enhancement for now, given that I'm not certain that it is
a bug.
