Comment:
I just did. You need the following patch to get Clang 11 working:

```
--- a/src/is_supported_platform.h
+++ b/src/is_supported_platform.h
@@ -30,7 +30,7 @@
 #define DT_SUPPORTED_X86 0
 #endif
 
-#if defined(__aarch64__) && (defined(__ARM_64BIT_STATE) && defined(__ARM_ARCH) && defined(__ARM_ARCH_8A) || defined(__APPLE__) || defined(__MINGW64__))
+#if defined(__aarch64__) && (defined(__ARM_64BIT_STATE) && defined(__ARM_ARCH) && (defined(__ARM_ARCH_8A) || __ARM_ARCH_PROFILE == 'A') || defined(__APPLE__) || defined(__MINGW64__))
 #define DT_SUPPORTED_ARMv8A 1
 #else
 #define DT_SUPPORTED_ARMv8A 0
```

It compiles fine without any modifications to the OpenMP SIMD statements and the generated binary seems to work perfectly, utilizing all four cores on the Raspberry Pi 3 Model B.

I've sent a Pull Request with this patch to the darktable devs, see darktable-org/darktable#12388.
