Analysis that detects all canonical Regions.

The RegionInfo pass detects all canonical regions in a function. The Regions are connected using the parent relation. This builds a Program Structure Tree.

Definition at line 672 of file RegionInfo.h.

◆ clearNodeCache()

◆ dump()

◆ getCommonRegion() [1/4]

Find the smallest region that contains two basic blocks.

Parameters

A The first basic block.
B The second basic block.

Returns

The smallest region that contains A and B.

Definition at line 848 of file RegionInfo.h.

◆ getCommonRegion() [2/4]

◆ getCommonRegion() [3/4]

◆ getCommonRegion() [4/4]

◆ getMaxRegionExit()

◆ getRegionFor()

◆ getTopLevelRegion()

◆ operator=()

◆ operator[]()

A shortcut for getRegionFor().

Parameters

Returns

The smallest region, that contains BB or NULL, if there is no region containing BB.

Definition at line 794 of file RegionInfoImpl.h.

References getRegionFor().

◆ print()

◆ releaseMemory()

◆ setRegionFor()

Set the smallest region that surrounds a basic block.

Parameters

BB The basic block surrounded by a region.
R The smallest region that surrounds BB.
