[PATCH] D157547: Arm64EC entry/exit thunks, consolidated.

[Billy Laws via Phabricator via cfe-commits]

bylaws added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64MCInstLower.cpp:59
+
+    StringRef Name = Printer.getSymbol(GV)->getName();
+    // Don't mangle ARM64EC runtime functions.
----------------
This mangling logic is also necessary for dllimported functions, as is visible if you compile:

__declspec(dllimport) long UnhandledExceptionFilter (void *ExceptionInfo);

void test() {
    UnhandledExceptionFilter(0);
}

With cl.exe /c and run dumpbin, without this link.exe will fail
