From c9d44a75d48ed8a9b9275b95be1fadaa562f3826 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas <heikki.linnakangas@iki.fi> Date: Mon, 12 Nov 2012 15:02:40 +0200 Subject: [PATCH] Silence "expression result unused" warnings in AssertVariableIsOfTypeMacro At least clang 3.1 generates those warnings. Prepend (void) to avoid them, like we have in AssertMacro. --- src/include/c.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/include/c.h b/src/include/c.h index 3b0fa9c4f01..a6c0e6e6505 100644 --- a/src/include/c.h +++ b/src/include/c.h @@ -736,15 +736,15 @@ typedef NameData *Name; StaticAssertStmt(__builtin_types_compatible_p(__typeof__(varname), typename), \ CppAsString(varname) " does not have type " CppAsString(typename)) #define AssertVariableIsOfTypeMacro(varname, typename) \ - StaticAssertExpr(__builtin_types_compatible_p(__typeof__(varname), typename), \ - CppAsString(varname) " does not have type " CppAsString(typename)) + ((void) StaticAssertExpr(__builtin_types_compatible_p(__typeof__(varname), typename), \ + CppAsString(varname) " does not have type " CppAsString(typename))) #else /* !HAVE__BUILTIN_TYPES_COMPATIBLE_P */ #define AssertVariableIsOfType(varname, typename) \ StaticAssertStmt(sizeof(varname) == sizeof(typename), \ CppAsString(varname) " does not have type " CppAsString(typename)) #define AssertVariableIsOfTypeMacro(varname, typename) \ - StaticAssertExpr(sizeof(varname) == sizeof(typename), \ - CppAsString(varname) " does not have type " CppAsString(typename)) + ((void) StaticAssertExpr(sizeof(varname) == sizeof(typename), \ + CppAsString(varname) " does not have type " CppAsString(typename))) #endif /* HAVE__BUILTIN_TYPES_COMPATIBLE_P */ -- GitLab
