Chris Lattner	ee9eb411ff	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102400 91177308-0d34-0410-b5e6-96231b3b80d8	2010-04-26 23:37:21 +00:00
Chris Lattner	10e7c60c04	emit a 0 byte instead of a noop if a function is empty on darwin. ... "0" is nice and target independent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94718 91177308-0d34-0410-b5e6-96231b3b80d8	2010-01-28 01:06:32 +00:00
Dan Gohman	36a0947820	Eliminate more uses of llvm-as and llvm-dis. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 23:54:48 +00:00
Chris Lattner	7cf9abff23	Add target triples to these so they don't fail on linux. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46496 91177308-0d34-0410-b5e6-96231b3b80d8	2008-01-29 06:26:07 +00:00
Bill Wendling	824a721560	If there's no instructions being emitted on X86 for a function, emit a ... nop. Emit the nop directly for PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46398 91177308-0d34-0410-b5e6-96231b3b80d8	2008-01-26 09:03:52 +00:00
