Well, my feeling would be: - Put in the patches that are testsuite-only (7, 8, 9 in my list) They should be harmless and significantly clean up test suite results on some platforms - Put in the solely platform-specific patches (3, 5, 6) I've tested these, and they definitely help on those platforms - The bitfield regression (1) seems a serious error affecting multiple platforms that really should be fixed, and the patch seems straightforward ... (All the above patches are already in mainline.) The remaining two PowerPC-related patches (not yet in mainline) are more difficult: - The displaced stepping regression is unfortunate, as it completely breaks a new feature. The patch *should* affect only PowerPC, but it does need to touch generic files (infrun.c), so there's always some risk. In any case, I'd prefer to get at least some feedback before putting it in ... - The Obj-C changes are not really a regression, so it may not really be critical to put those in. On the other hand, they just touch Obj-C code (except for one PowerPC-specific bugfix), and they drastically improve the situation on PowerPC-64, so it would be nice ... Again, I'd definitely like some feedback first. Thanks, Ulrich -- Dr. Ulrich Weigand GNU Toolchain for Linux on System z and Cell BE Ulrich.Weigand@de.ibm.com
