Hi Gustavo,

thanks for providing the webrevs. I have ran the StrictMath jck tests which fail when building with -O3 and without -ffp-contract=off: FailedTests: api/javalang/StrictMath/desc.html#acos javasoft.sqe.tests.api.java.lang.StrictMath.acostest api/javalang/StrictMath/desc.html#asin javasoft.sqe.tests.api.java.lang.StrictMath.asintest api/javalang/StrictMath/desc.html#atan javasoft.sqe.tests.api.java.lang.StrictMath.atantest api/javalang/StrictMath/desc.html#atan2 javasoft.sqe.tests.api.java.lang.StrictMath.atan2test api/javalang/StrictMath/desc.html#cos javasoft.sqe.tests.api.java.lang.StrictMath.costest api/javalang/StrictMath/desc.html#exp javasoft.sqe.tests.api.java.lang.StrictMath.exptest api/javalang/StrictMath/desc.html#log javasoft.sqe.tests.api.java.lang.StrictMath.logtest api/javalang/StrictMath/desc.html#sin javasoft.sqe.tests.api.java.lang.StrictMath.sintest api/javalang/StrictMath/desc.html#tan javasoft.sqe.tests.api.java.lang.StrictMath.tantest api/javalang/StrictMath/index.html#expm1 javasoft.sqe.tests.api.java.lang.StrictMath.expm1Tests -TestCaseID ALL api/javalang/StrictMath/index.html#log10 javasoft.sqe.tests.api.java.lang.StrictMath.log10Tests -TestCaseID ALL api/javalang/StrictMath/index.html#log1p javasoft.sqe.tests.api.java.lang.StrictMath.log1pTests -TestCaseID ALL All of them have passed when building with -O3 and -ffp-contract=off (on linuxppc64le).

Thank you very much for running the additional StrictMath jck tests against the change!
