| | | | | | | | | | | | | all attributes have now a \t before and after, as done for '.type'.

* This is the first patch to put the needed bits in place to eventually allow codeKevin Enderby2010-02-231-0/+9
| | | | | | | | | | | | to be aligned with optimal nops. This patch does not change any functionality and when the compiler is changed to use EmitCodeAlignment() it should also not change the resulting output. Once the compiler change is made and everything looks good the next patch with the table of optimal X86 nops will be added to WriteNopData() changing the output. There are many FIXMEs in this patch which will be removed when we have better target hooks (coming soon I hear). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96963 91177308-0d34-0410-b5e6-96231b3b80d8
