Subject: Remove two initialization functions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=37163dcf1a1b32115a49a51410e352366cc02fbc;p=binutils-gdb.git

Remove two initialization functions

I noticed a couple of initialization functions that aren't really
needed, and that currently require explicit calls in gdb_init.  This
patch removes these functions, simplifying gdb a little.

Regression tested on x86-64 Fedora 34.
