erichkeane	380954b26f	Fix test failure introduced in ab187bb ... This patch, #147285 introduced a test that used preserve_none/preserve_all/preserve_most for the purposes of validating its ast-dump. However, this attribute isn't supported on some platforms, so this patch adds a triple to the test to ensure we try to run it as a non-supported platform. As this is simply an ast-dump test, there is no value to running it on other configurations.	2025-07-09 06:18:49 -07:00
Andreas C. Osowski	ab187bbd3a	[clang][AST] Fix positioning of preserve cconv attributes in TypePrinter (#147285) ... TypePrinter currently generates function pointer types that do not compile when using the `preserve_.*` calling conventions as per https://clang.llvm.org/docs/AttributeReference.html#preserve-all ff. Running clang with `-Xclang -ast-print` on the following: ```cc using IN1 = void (__attribute__((preserve_most)) *)(); using IN2 = __attribute__((preserve_most)) void (*) (); ``` outputs: ```cc using IN1 = void (*)() __attribute__((preserve_most)); using IN2 = void ((*))() __attribute__((preserve_most)); ``` However, this does not compile: ```cc <source>:3:23: error: expected ';' after alias declaration 3 | using IN1 = void (*)() __attribute__((preserve_most)); ``` This PR updates TypePrinter such that output is correct and compiles: ```cc using IN1 = __attribute__((preserve_most)) void (*)(); using IN2 = __attribute__((preserve_most)) void ((*))(); ``` I've verified via `-ast-dump` that the AST looks equivalent.	2025-07-09 08:52:56 -04:00
