the related comma pasting extension. In certain cases, we used to get two diagnostics for what is essentially one extension. This change suppresses the first diagnostic in certain cases where we know we're going to print the second diagnostic. The diagnostic is redundant, and it can't be suppressed in the definition of the macro because it points at the use of the macro, so we want to avoid printing it if possible. The implementation works by detecting constructs which look like comma pasting at the time of the definition of the macro; this information is then used when the macro is used. (We can't actually detect whether we're using the comma pasting extension until the macro is actually used, but we can detecting constructs which will be comma pasting if the varargs argument is elided.) <rdar://problem/12292192> llvm-svn: 167907 |
