------- Comment #2 from yakov at emc dot com 2007-01-18 19:18 ------- Subject: Re: compiler inlines slightly invalid function without warning
gcc -O2 -Wall -c -fno-inline rtv.c rtv.c: In function `compute_tables_error_code': rtv.c:18: warning: control reaches end of non-void function gcc -O2 -Wall -c rtv.c <-- no warning here With '-fno-inline' compiler generates very useful warning - the return stmt has been missing. This is my point. sincerely, yakov pinskia at gcc dot gnu dot org wrote: >------- Comment #1 from pinskia at gcc dot gnu dot org 2007-01-18 18:00 >------- >I think you mean the following options: >-O2 -Wall -Winline >and with 4.0.0 and above I get: >t.c:9: warning: control may reach end of non-void function >'compute_tables_error_code' being inlined >or: >t.c: In function 'compute_tables_error_code': >t.c:19: warning: control reaches end of non-void function > >PS this is not really invalid code, just undefined code. > > > > -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30502
