Subject: Remove some dead code from the Rust value printer
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=925ea601f1892c6eb344e2c916f0ef448b42b606;p=binutils-gdb.git

Remove some dead code from the Rust value printer

This removes a bit of dead code from the Rust value printer.  This
code wasn't always dead -- it fixed a real bug, and a test case was
added for it.  However, once val_print was removed, it became
unnecessary.
