Jakob Stoklund Olesen 201f2463a7 Don't treat a partial <def,undef> operand as a read. Normally, a partial register def is treated as reading the super-register unless it also defines the full register like this: %vreg110:sub_32bit<def> = COPY %vreg77:sub_32bit, %vreg110<imp-def> This patch also uses the <undef> flag on partial defs to recognize non-reading operands: %vreg110:sub_32bit<def,undef> = COPY %vreg77:sub_32bit This fixes a subtle bug in RegisterCoalescer where LIS->shrinkToUses would treat a coalesced copy as still reading the register, extending the live range artificially. My test case only works when I disable DCE so a dead copy is left for RegisterCoalescer, so I am not including it. <rdar://problem/9967101> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138018 91177308-0d34-0410-b5e6-96231b3b80d8		2011-08-19 00:30:17 +00:00

docs	Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL.	2011-08-16 22:09:43 +00:00
