Subject: gdb: Add test for some error cases of @entry usage
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b1b189e04cb5ea5da1cbb07bd6cceccd4d2ac969;p=binutils-gdb.git

gdb: Add test for some error cases of @entry usage

Adds a test that using @entry for a non-parameter, or for an unknown
symbol, both give the expected error.  This error message was
previously untested.

gdb/testsuite/ChangeLog:

	* gdb.arch/amd64-entry-value.exp: Test using @entry on a
	non-parameter, and on an unknown symbol.
