◆ MergeConstantGlobals

Whether we should merge constant global variables.

Definition at line 32 of file GlobalMerge.h.

◆ MergeExternal

bool llvm::GlobalMergeOptions::MergeExternal = true

◆ MinSize

unsigned llvm::GlobalMergeOptions::MinSize = 0

Definition at line 25 of file GlobalMerge.h.

◆ SizeOnly

bool llvm::GlobalMergeOptions::SizeOnly = false

Whether we should try to optimize for size only.

Currently, this applies a dead simple heuristic: only consider globals used in minsize functions for merging. FIXME: This could learn about optsize, and be used in the cost model.
