intersects()

bool llvm::DWARFAddressRange::intersects ( const DWARFAddressRange &  RHS ) const

inline

Returns true if [LowPC, HighPC) intersects with [RHS.LowPC, RHS.HighPC).

merge()

bool llvm::DWARFAddressRange::merge ( const DWARFAddressRange &  RHS )

inline

Union two address ranges if they intersect.

This function will union two address ranges if they intersect by modifying this range to be the union of both ranges. If the two ranges don't intersect this range will be left alone.

Parameters

RHS	Another address range to combine with.

Returns

false if the ranges don't intersect, true if they do and the ranges were combined.

References HighPC, intersects(), LowPC, and RHS.

valid()

bool llvm::DWARFAddressRange::valid ( ) const

inline

Returns true if LowPC is smaller or equal to HighPC.

This accounts for dead-stripped ranges.
