◆ GroupByUse

bool llvm::GlobalMergeOptions::GroupByUse = true

◆ IgnoreSingleUse

bool llvm::GlobalMergeOptions::IgnoreSingleUse = true

◆ MaxOffset

unsigned llvm::GlobalMergeOptions::MaxOffset = 0

◆ MergeConstAggressive

bool llvm::GlobalMergeOptions::MergeConstAggressive = false

Whether we should merge constant global variables aggressively without looking at use.

Definition at line 34 of file GlobalMerge.h.

◆ MergeConstantGlobals

bool llvm::GlobalMergeOptions::MergeConstantGlobals = false

Whether we should merge constant global variables.

Definition at line 31 of file GlobalMerge.h.

◆ MergeExternal

bool llvm::GlobalMergeOptions::MergeExternal = true

Whether we should merge global variables that have external linkage.

Definition at line 29 of file GlobalMerge.h.

◆ MinSize

unsigned llvm::GlobalMergeOptions::MinSize = 0

◆ 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.
