* It turns out that the two dimensional vectors were causing big slowdownsChris Lattner2004-02-091-32/+34
| | | | | | | | | | | | | | | | | | in this for programs with lots of types (like the testcase in PR224). The problem was that the type ID that the outer vector was using was not very dense (as many types are getting resolved), so the vector is large and gets reallocated a lot. Since there are a lot of values in the program (the .ll file is 10M), each reallocation has to copy the subvectors, which is also quite slow (this wouldn't be a problem if C++ supported move semantics, but it doesn't, at least not yet :( Changing the outer data structure to a map speeds a release build of llvm-as up from 11.21s to 5.13s on the testcase in PR224. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11244 91177308-0d34-0410-b5e6-96231b3b80d8
* When resolving upreferences, if multiple uprefs will be resolved to the sameChris Lattner2004-02-091-6/+24
| | | | | | | | | type at the same time, resolve the upreferences to each other before resolving it to the outer type. This shaves off some time from the testcase in PR224, from 25.41s -> 21.72s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11241 91177308-0d34-0410-b5e6-96231b3b80d8

* Instead of searching the entire type graph for a type to determine if itChris Lattner2004-02-091-8/+29
| | | | | | | | | | | | contains the type we are looking for, just search the immediately used types. We can only do this because we keep the "current" type in the nesting level as we decrement upreferences. This change speeds up the testcase in PR224 from 50.4s to 22.08s, not too shabby. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11221 91177308-0d34-0410-b5e6-96231b3b80d8
