[Bug objc/43535] ICE on objc.dg/objc-gc-4.m -fgnu-runtime
--- Comment #1 from developer at sandoe-acoustics dot co dot uk 2010-03-26 12:16 --- I believe that this test was not previously carried out with -fgnu-runtime . So, technically I think it's a failed New test rather than a regression (but I will triple-check a little later). In any event, I don't suppose we want an ICE as a response to a command line error. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43535

I think there is an already filed bug about this option with the gnu runtime also. This option should not be supported or a nop there.

--- Comment #4 from developer at sandoe-acoustics dot co dot uk 2010-03-26 16:36 --- (In reply to comment #3) Subject: Re: ICE on objc.dg/objc-gc-4.m -fgnu-runtime This option should not be supported or a nop there. if gc is incompatible with gnu runtime then that should be thrown out either in options processing - or in objc init.. .. I'm happy to take on doing the latter ; the question then is error or remove the flag and warn? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43535
