This built-in function returns exp1 if const_exp, which is a constant expression that must be able to be determined at compile time, is nonzero. --> Otherwise it returns 0. should be --> Otherwise it returns exp2. This is confusing and misleading for the actual functionailty of the builtin, it shold be changed. -- Summary: misleading __builtin_choose_expr documentation error Product: gcc Version: 4.0.1 Status: UNCONFIRMED Severity: minor Priority: P3 Component: web AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: twang at apple dot com GCC build triplet: powerpc-apple-darwin8 GCC host triplet: powerpc-apple-darwin8 GCC target triplet: powerpc-apple-darwin8 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28575
