ScalarizeLoadStore

bool llvm::ScalarizerPassOptions::ScalarizeLoadStore = false

Allow the scalarizer pass to scalarize loads and store.

This is disabled by default because having separate loads and stores makes it more likely that the -combiner-alias-analysis limits will be reached.

ScalarizeMinBits

unsigned llvm::ScalarizerPassOptions::ScalarizeMinBits = 0

Instruct the scalarizer pass to attempt to keep values of a minimum number of bits.

Split vectors larger than this size into fragments, where each fragment is either a vector no larger than this size or a scalar.

Instructions with operands or results of different sizes that would be split into a different number of fragments are currently left as-is.

ScalarizeVariableInsertExtract

bool llvm::ScalarizerPassOptions::ScalarizeVariableInsertExtract = true

Allow the scalarizer pass to scalarize insertelement/extractelement with variable index.
