constraints.md (Q constraint): Document its use for Thumb-1.
2016-10-25 Thomas Preud'homme <thomas.preudhomme@arm.com>
gcc/
* config/arm/constraints.md (Q constraint): Document its use for
Thumb-1.
(Pf constraint): New constraint for relaxed, consume or relaxed memory
models.
* config/arm/sync.md (atomic_load<mode>): Add new ARMv8-M Baseline only
alternatives to allow any register when memory model matches Pf and
thus lda is used, but only low registers otherwise. Use unpredicated
output template for Thumb-1 targets.
(atomic_store<mode>): Likewise for stl.
(arm_load_exclusive<mode>): Add new ARMv8-M Baseline only alternative
whose output template does not have predication.
(arm_load_acquire_exclusive<mode>): Likewise.
(arm_load_exclusivesi): Likewise.
(arm_load_acquire_exclusivesi): Likewise.
(arm_store_release_exclusive<mode>): Likewise.
(arm_store_exclusive<mode>): Use unpredicated output template for
Thumb-1 targets.
