A backport of this patch to gcc-3.3.3 was written by SUGIOKA Toshinobu
and is (mistakenly) archived as
http://www.m17n.org/linux-sh/ml/linux-sh/2003-02/msg00014.html
It causes no regressions on sh4 in gcc-3.3.3-20040131's C, C++,
and libstdc++ testsuites, nor in the part of the glibc-2.3.2
testsuite that I usually run.
I was surprised and pleased to see that it also fixed my testcase for PR11587!
