- Subject: [libjava] Fix md5test, shatest on Tru64 UNIX with native libiconv (PR libgcj/49314)
As described in the PR, unless the UTF-8 encoding of \ufeff is padded
with a NUL byte, the iconv_init test fails for the native Tru64 UNIX
libiconv, iconv_byte_swap isn't set correctly and later iconv calls
fail. This patch fixes this, allowing the arraycopy testcase in the PR
and the actual md5test and shatest testcases to succeed. This way, I
get clean libjava testsuite results.
Tested by rebuilding libgcj.so with the fixed natIconv.cc. A full
rebuild and test of libgcj is currently running on alpha-dec-osf5.1b.
Ok for mainline if it passes?
Thanks.
