This is valid for little-endian targets, but fails on big-endian targets. This is fixed by determining the expected value in an endianness-independent way. gdb/testsuite/ChangeLog: * gdb.dwarf2/implptrpiece.exp: Fix check for big-endian targets. --- gdb/testsuite/gdb.dwarf2/implptrpiece.exp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/gdb/testsuite/gdb.dwarf2/implptrpiece.exp b/gdb/testsuite/gdb.dwarf2/implptrpiece.exp index af7dd37..3f6e0d6 100644 --- a/gdb/testsuite/gdb.dwarf2/implptrpiece.exp +++ b/gdb/testsuite/gdb.dwarf2/implptrpiece.exp @@ -119,4 +119,7 @@ if ![runto_main] { return -1 } -gdb_test "print/d p\[-1\]" " = 0" +# Access the second byte of s through an implicit pointer to the third +# byte of s, using a negative offset.
