------- Comment #9 from socketpair at gmail dot com 2010-05-06 15:03 ------- > Not if you make the output unused by not using it. I do not understand why gcc distinguish between 'specifying register as output' and 'specifying as clobbering'.
I always considered, that 'clobber list' specify list of items which may be changed *AFTER* the end of instruction(s). So I do not understand why adding eax in clobber list will break compilation. I found some posts where people create size_t dummy; and specify this variable as output. insted of just specifying this register in clobber-list. Why not to fix bug I have reported? Maybe convert to feature? -- socketpair at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43998
