Subject: Do not push 'cpsr' register on Darwin/arm
X-Git-Tag: v8.0.0~376
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e82235769795e9501f08b64e763b7ac3b3164a7e;p=platform%2Fupstream%2Flibgc.git

Do not push 'cpsr' register on Darwin/arm

ARM cpsr stands for Control Program State Register.
It cannot contain a pointer.

* darwin_stop_world.c [ARM32] (GC_stack_range_for): Ignore cpsr
register; update comment.
