Subject: Trivially simplify rust_language::print_enum
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8ac460b742bc7f49acbcd78f8822386f56814055;p=binutils-gdb.git

Trivially simplify rust_language::print_enum

rust_language::print_enum computes:

  int nfields = variant_type->num_fields ();

... but then does not reuse this in one spot.  This patch corrects the
oversight.
