How is this different from arm_thumb2_ok and !arm_thumb2_ok ?
If l Iook at arm_thumb2 that appears to be identical to what
arm_thumb2_ok does.
proc check_effective_target_arm_thumb2_ok { } {
return [check_no_compiler_messages arm_thumb2_ok assembly {
#if !defined(__thumb2__)
#error FOO
#endif
} "-mthumb"]
}
+# Return 1 is this is an ARM target where is Thumb-2 used.
+
+proc check_effective_target_arm_thumb2 { } {
+ return [check_no_compiler_messages arm_thumb2 assembly {
+ #if !defined(__thumb2__)
+ #error FOO
+ #endif
+ } ""]
+}
+
Or am I missing something ?
