Subject: tests/tcg/xtensa: restore vecbase SR after test
X-Git-Tag: v7.1.0-rc0~112^2~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8164f14bb98dce986b755af4b3dfee3eb99c95a1;p=thirdparty%2Fqemu.git

tests/tcg/xtensa: restore vecbase SR after test

Writing garbage into the vecbase SR results in hang in the subsequent
tests that expect to raise an exception. Restore vecbase SR to its
reset value after the test.
