Tim Northover	fb26d9a286	MIR: remove explicit "noVRegs" property. We can infer this from the incoming MIR, so there's no reason to represent it with a special flag. llvm-svn: 304246	2017-05-30 21:28:57 +00:00
Tim Northover	0d98b03b9f	ARM: avoid clobbering register in v6 jump-table expansion. If we got unlucky with register allocation and actual constpool placement, we could end up producing a tTBB_JT with an index that's already been clobbered. Technically, we might be able to fix this situation up with a MOV, but I think the constant islands pass is complex enough without having to deal with more weird edge-cases. llvm-svn: 297871	2017-03-15 18:38:13 +00:00
