Ok, with a few fixes...

+/* Test for CDE #prama target macros. */

Typo in "pragma" in the comment.
+# A series of routines are created to 1) check if a given architecture is
+# effective (check_effective_target_*_ok) and then 2) give the corresponding
+# flags that enable the architecture (add_options_for_*).
+# The series includes:
+# arm_v8m_main_cde: Armv8-m CDE (Custom Datapath Extension).
+# arm_v8m_main_cde_fp: Armv8-m CDE with FP registers.
+# arm_v8_1m_main_cde_mve: Armv8.1-m CDE with MVE.
+# Usage:
+# /* { dg-require-effective-target arm_v8m_main_cde_ok } */
+# /* { dg-add-options arm_v8m_main_cde } */
+# The tests are valid for Arm.
+
+foreach { armfunc armflag armdef } {
New effective target checks need to be documented in doc/invoke.texi
Ok with those changes.
