Subject: [PATCH 17/46] Fix gdb.dwarf2/shortpiece.exp on s390x
|
|
|
|
On s390x-linux, I run into:
|
|
...
|
|
(gdb) p (short []) s1^M
|
|
$3 = {0, 1, 0, <optimized out>}^M
|
|
(gdb) FAIL: gdb.dwarf2/shortpiece.exp: p (short []) s1
|
|
...
|
|
while this is expected:
|
|
...
|
|
(gdb) p (short []) s1^M
|
|
$3 = {1, 0, 0, <optimized out>}^M
|
|
(gdb) PASS: gdb.dwarf2/shortpiece.exp: p (short []) s1
|
|
...
|
|
|
|
The type of s1 is:
|
|
...
|
|
(gdb) ptype s1
|
|
type = struct S {
|
|
myint a;
|
|
myushort b;
|
|
}
|
|
...
|
|
so the difference is due the fact that viewing an int as two shorts gives
|
|
different results depending on the endianness.
|
|
|
|
Fix this by allowing both results.
|
|
|
|
Tested on x86_64-linux and s390x-linux.
