Subject: [Bug libgcj/40860] [4.4/4.5 regression] regressions in libjava testsuite on arm-linux

------- Comment #22 from mikpe at it dot uu dot se 2010-03-17 21:23 -------
I did another binutils experiment. I reverted my patch to disable general
merging of table entries, and instead disabled generating new and merging
cantunwind entries. With that binutils libjava regressed just like with vanilla
post-2.19.1 binutils. The general merging bit seems to be the problem.
