* Add a getPointerOperand() helper function to VAArgInst, for consistencyDan Gohman2010-09-091-0/+4

* For each instruction itinerary class, specify the number of micro-ops eachEvan Cheng2010-09-093-1/+14
| | | | | | | | | | | instruction in the class would be decoded to. Or zero if the number of uOPs must be determined dynamically.

* Refactor code-size reduction estimation methods out of InlineCostAnalyzer ↵Owen Anderson2010-09-092-10/+12
| | | | | | | | | | | | and into CodeMetrics. They don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113499 91177308-0d34-0410-b5e6-96231b3b80d8
