From 451650eaacd5e482380f2b0e506fc81f5aa92fc7 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Tue, 17 Feb 2026 10:06:39 +0100 Subject: [PATCH] Test most StaticAssert macros in C++ extensions Most of the StaticAssert macros already worked in C++ with Clang and GCC:(the only compilers we're currently testing C++ extension support for). This adds a regression test for them in our test C++ extension, so we can safely change their implementation without accidentally breaking C++. The only macros that StaticAssert macros that don't work yet are the StaticAssertVariableIsOfType and StaticAssertVariableIsOfTypeMacro. These will be added in a follow-on commit.
