Chris Lattner a958cbfe36 Disable folding sext(trunc(x)) -> x (and other similar cast/cast cases) when the ... trunc has multiple uses. Codegen is not able to coalesce the subreg case correctly and so this leads to higher register pressure and spilling (see PR5997). This speeds up 256.bzip2 from 8.60 -> 8.04s on my machine, ~7%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93200 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-11 22:45:25 +00:00

Linker	Fixed linking of modules containing aliases to constant bitcasts. Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).	2010-01-09 16:27:31 +00:00
