--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Now I have make[3]: Entering directory `/home/abuild/rguenther/obj-early-lto-debug-g/gcc/ada/tools' ../../gnatbind -I- -I../rts -I. -I/space/rguenther/src/svn/early-lto-debug/gcc/ada -o b_gnatm.adb gnatmake.ali error: "s-stalib.adb" and "gnatmake.adb" compiled with different exception handling mechanisms error: "s-secsta.adb" and "gnatmake.adb" compiled with different exception handling mechanisms ... not sure what happened this time but it's really annoying to have to rm -Rf my whole dev tree and re-build it all the time just to be able to look at a single gnat testcase. Oh, and that I can't cut&paste from gnat.dg testsuite logs and add -v -save-temps to see and debug subcommands invoked is another thing. Putting some "how to debug ada fails in acats, how to debug ada fails in gnat.dg" hints on the wiki would be nice.
