The ARM assembler recognises @ symbol as a comment marker and
therefore is unable to assemble some of gdb.dwarf2 testsuite tests.
This patch replaces all occurrences of @ symbol with % sign to allow
tests stay compatible with both ARM and x86 assembly. This patch has
been tested on x86_64 and ARMv7 targets.
gdb/testsuite/ChangeLog:
2013-07-19 Omair Javaid <Omair.Javaid@linaro.org>
* gdb.dwarf2/fission-reread.S: Replace @ sign with % sign to remove
assembler errors on arm.
* gdb.dwarf2/mac-fileno.S: Likewise.
* gdb.dwarf2/member-ptr-forwardref.S: Likewise.
* gdb.dwarf2/pr13961.S: Likewise.

/* Testcase to exercise the code path in bug 13961.
|
|
|
|
Compiled from:
|
|
|
|
class foo
|
|
{
|
|
public:
|
|
int bar;
|
|
};
|
|
|
|
foo baz;
|
|
|
|
int
|
|
main ()
|
|
{
|
|
return 0;
|
|
}
|
|
|
|
And then manually edited to insert the necessary DW_AT_specification
|
|
entries to trigger the desired code path.
|
|
There's no real need to make this architecture-specific, so it has been
|
|
further hand-edited to support that.
