Hi, The header in gcc/config/arm/constraints.md list all the ARM-specific constraints defined and for which targets they are but miss a couple of them. This patch add the missing Cs and US constraints to the list.
Patch was tested by verifying that arm-none-eabi-gcc cross-compiler can still be build (ie the comment remains a comment). diff --git a/gcc/config/arm/constraints.md b/gcc/config/arm/constraints.md index 42935a4..2d9ffb8 100644 --- a/gcc/config/arm/constraints.md +++ b/gcc/config/arm/constraints.md @@ -21,7 +21,7 @@ ;; The following register constraints have been used: ;; - in ARM/Thumb-2 state: t, w, x, y, z ;; - in Thumb state: h, b -;; - in both states: l, c, k, q, US +;; - in both states: l, c, k, q, Cs, Ts, US ;; In ARM state, 'l' is an alias for 'r' ;; 'f' and 'v' were previously used for FPA and MAVERICK registers.
