--- Comment #9 from Steve Ellcey <sje at gcc dot gnu.org> 2012-08-15 18:01:58 UTC --- That is correct, the original test fails with -fcompare-debug on a mipsel* target or a mips* (big-endian) target. The cutdown test case only fails on mips* big-endian targets. The original gives: g++: error: x.i: -fcompare-debug failure (length) The cutdown one gives: gcc: error: x.i: -fcompare-debug failure I am going to use delta to create a cut-down test case that fails in little endian mode.
