on darwin empty functions need to codegen into something of non-zero length, otherwise labels get incorrectly merged. We handled this by emitting a ".byte 0", but this isn't correct on thumb/arm targets where the text segment needs to be a multiple of 2/4 bytes. Handle this by emitting a noop. This is more gross than it should be because arm/ppc are not fully mc'ized yet. This fixes rdar://7908505 llvm-svn: 102400 2010-04-27 01:37:21 +02:00			`; RUN: llc < %s -march=x86 \| grep nop`
Add target triples to these so they don't fail on linux. llvm-svn: 46496 2008-01-29 07:26:07 +01:00			`target triple = "i686-apple-darwin8"`

If there's no instructions being emitted on X86 for a function, emit a nop. Emit the nop directly for PPC. llvm-svn: 46398 2008-01-26 10:03:52 +01:00
