X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=74d877e5221f3459aa9f4f9354194b714d306e18;p=binutils-gdb.git

gdb: new function to wrap up executing command line scripts/commands

Small refactor to wrap up executing the scripts and commands passed
using the -x, -ex, -ix, -iex command line flags.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* main.c (execute_cmdargs): New function.
	(captured_main_1): Make use of execute_cmdargs.
