------- Comment #8 from joseph at codesourcery dot com 2008-12-15 00:31 ------- Subject: Re: __builtin_constant_p(t) ? t : 1 is not considered a constant integer expression
I also added more __builtin_constant_p tests (gcc.dg/bconstp-[34].c) to c-4_5-branch, following this discussion, to verify more of the model for how __builtin_constant_p works in constant expressions. In general the constant expressions tests there (both those added there, and the previously existing constant expressions / overflow diagnostics tests, most of which have had XFAILs removed on the branch) reflect my interpretation for the GNU C language of both the standard constant expressions rules where unclear and of how the rules should be applied to new language features in GNU C that aren't in ISO C. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38377
