* New virtual registers created for spill intervals should inherit allocation ↵Jakob Stoklund Olesen2009-11-302-1/+7
| | | | | | | | | | | | | | | | | | | hints from the original register. This helps us avoid silly copies when rematting values that are copied to a physical register: leaq _.str44(%rip), %rcx movq %rcx, %rsi call _strcmp becomes: leaq _.str44(%rip), %rsi call _strcmp The coalescer will not touch the movq because that would tie down the physical register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90163 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | branches even when optimizing for code size. Unless we find evidence to the contrary in the future, the special treatment for indirect branches does not have a significant effect on code size, and performance still matters with -Os. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90147 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | for all the processors where I have tried it, and even when it might not help performance, the cost is quite low. The opportunities for duplicating indirect branches are limited by other factors so code size does not change much due to tail duplicating indirect branches aggressively. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90144 91177308-0d34-0410-b5e6-96231b3b80d8

* Only print edgeSourceLabels if they are not emptyTobias Grosser2009-11-301-13/+39
| | | | | | | | | | Graphviz can layout the graphs better if a node does not contain source ports. Therefore only print the ports if the source ports are useful, that means are not labeled with the empty string "". This patch also simplifies graphs without any edgeSourceLabels e.g. the dominance trees. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | was being added to the Result vector, but not being put in the cache. This means that if the cache was reused wholesale for a later query that it would be missing this entry and we'd do an incorrect load elimination.
