ARM: teach backend about WatchOS and TvOS libcalls. The most substantial changes are again for watchOS: libcalls are hard-float if needed and sincos has a different calling convention. llvm-svn: 251571 2015-10-28 23:51:16 +01:00			`; RUN: llc -mtriple=thumbv7k-apple-watchos2.0 -o - %s \| FileCheck %s`

ARM: stop emitting blx instructions for most calls on MachO. I'm really not sure why we were in the first place, it's the linker's job to convert between BL/BLX as necessary. Even worse, using BLX left Thumb calls that could be locally resolved completely unencodable since all offsets to BLX are multiples of 4. rdar://26182344 llvm-svn: 269101 2016-05-10 21:17:47 +02:00			`; CHECK: bl ___sincos_stret`
