From c0ccb8bb17028fe0dda139c0972c0125d10e6053 Mon Sep 17 00:00:00 2001 From: Andrew Trick Date: Fri, 20 Apr 2012 20:05:28 +0000 Subject: SparseSet: Add support for key-derived indexes and arbitrary key types. This nicely handles the most common case of virtual register sets, but also handles anticipated cases where we will map pointers to IDs. The goal is not to develop a completely generic SparseSet template. Instead we want to handle the expected uses within llvm without any template antics in the client code. I'm adding a bit of template nastiness here, and some assumption about expected usage in order to make the client code very clean. The expected common uses cases I'm designing for: - integer keys that need to be reindexed, and may map to additional data - densely numbered objects where we want pointer keys because no number->object map exists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155227 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAllocFast.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/RegAllocFast.cpp') diff --git a/lib/CodeGen/RegAllocFast.cpp b/lib/CodeGen/RegAllocFast.cpp index e09b7f8d26..70fbfd4c5c 100644 --- a/lib/CodeGen/RegAllocFast.cpp +++ b/lib/CodeGen/RegAllocFast.cpp @@ -77,7 +77,7 @@ namespace { explicit LiveReg(unsigned v) : LastUse(0), VirtReg(v), PhysReg(0), LastOpNum(0), Dirty(false) {} - unsigned getSparseSetKey() const { + unsigned getSparseSetIndex() const { return TargetRegisterInfo::virtReg2Index(VirtReg); } }; -- cgit v1.2.3-18-g5258
