Hi, I have builtin __function_size(foobar) that is applied to functions. This should be folded to a symbol foobar@size.
The problem comes when I mark in the fold_builtin function in my backend that DECL_PRESERVE(foobar) = 1; The reason I need to do this is so that foobar is not removed if we happen to use __function_size(foobar) since I will need foobar during linking phase to do some calculations with regards to its size. As a consequence of DECL_PRESERVE(foobar) I cannot build GCC with -- enable-checking because it fails the check in: fold-const.c and shows the message: internal compiler error: fold check: original tree changed by fold This is really annoying since I like to run my tests with --enable- checking=full to get the most of the checks in GCC but I can't with this issue lying around. I am open to suggestions on how to mark the function as preserve is the function name is referred to by a function builtin. Cheers, -- PMatos
