Author: dim Date: Fri Jun 7 18:52:36 2019 New Revision: 348787 URL: https://svnweb.freebsd.org/changeset/base/348787 Log: MFC r348500: Partially revert r271349, which disabled the msun cexp test #4 on i386. Ensure the expected result is stored first in a volatile variable with the desired type. This makes all the tests succeed. Slightly changed from the original pull request, but functionally the same.
