Subject: [PATCH 4/6] [gdb/testsuite] Handle asm frame in
|
||
|
|
gdb.python/py-missing-objfile.exp
|
||
|
|
|
||
|
|
On arm-linux, with test-case gdb.python/py-missing-objfile.exp I get:
|
||
|
|
...
|
||
|
|
(gdb) whatis global_exec_var^M
|
||
|
|
type = volatile exec_type^M
|
||
|
|
(gdb) FAIL: $exp: initial sanity check: whatis global_exec_var
|
||
|
|
...
|
||
|
|
instead of the expected "type = volatile struct exec_type".
|
||
|
|
|
||
|
|
The problem is that the current language is ASM instead of C, because the
|
||
|
|
inner frame at the point of the core dump has language ASM:
|
||
|
|
...
|
||
|
|
#0 __libc_do_syscall () at libc-do-syscall.S:47
|
||
|
|
#1 0xf7882920 in __pthread_kill_implementation () at pthread_kill.c:43
|
||
|
|
#2 0xf784df22 in __GI_raise (sig=sig@entry=6) at raise.c:26
|
||
|
|
#3 0xf783f03e in __GI_abort () at abort.c:73
|
||
|
|
#4 0x009b0538 in dump_core () at py-missing-objfile.c:34
|
||
|
|
#5 0x009b0598 in main () at py-missing-objfile.c:46
|
||
|
|
...
|
||
|
|
|
||
|
|
Fix this by manually setting the language to C.
|
||
|
|
|
||
|
|
Tested on arm-linux and x86_64-linux.
