+ * lib/target-supports.exp (check_effective_target_arm_arch_FUNC_ok):
+ Test for null definitions instead of them being undefined. Add entry
+ for ARMv7VE. Reindent entry for ARMv8-M Baseline. Add comment warning
+ about using the effective target for architecture extension.
+ (check_effective_target_arm_arch_v7ve_ok): Remove.
+ (add_options_for_arm_arch_v7ve): Likewise.

# can be selected and a routine to give the flags to select that architecture
# Note: Extra flags may be added to disable options from newer compilers
# (Thumb in particular - but others may be added in the future).
-# -march=armv7ve is special and is handled explicitly after this loop because
-# it needs more than one predefine check to identify.
+# Warning: Do not use check_effective_target_arm_arch_*_ok for architecture
+# extension (eg. ARMv8.1-A) since there is no macro defined for them. See
+# how only __ARM_ARCH_8A__ is checked for ARMv8.1-A.
