[Bug translator/5377] New: Wildcards following the dwarf probe are expanded incorrectly

["mhiramat at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

I found wildcards at the tail of the dwarf probes were expanded incorrectly.

For example,
---
 probe kernel.function("sys_read").* {}
---
This script was expanded as below (output of 'stap -p2');
---
 # probes
 kernel.function("sys_read@fs/read_write.c:358") /* pc=0x807ff */ /* <-
kernel.function("sys_read").* */
 kernel.function("sys_read@fs/read_write.c:358") /* pc=0x807ff */ /* <-
kernel.function("sys_read").* */
 kernel.function("sys_read@fs/read_write.c:358") /* pc=0x807ff */ /* <-
kernel.function("sys_read").* */
---
I expected that it should be expanded as below;
---
 # probes
 kernel.function("sys_read@fs/read_write.c:358").call /* pc=0x807ff */ /* <-
kernel.function("sys_read").* */
 kernel.function("sys_read@fs/read_write.c:358").return /* pc=0x807ff */ /* <-
kernel.function("sys_read").* */
---

And also,
---
 probe kernel.function("sys_read").ret* {}
---
This was expanded as below;
---
 # probes
 kernel.function("sys_read@fs/read_write.c:358") /* pc=0x807ff */ /* <-
kernel.function("sys_read").ret* */
---
But it should be expanded as below;
---
 # probes
 kernel.function("sys_read@fs/read_write.c:358").return /* pc=0x807ff */ /* <-
kernel.function("sys_read").ret* */
---

Thanks,
