void StackMaps::recordStackMap | ( | const MCSymbol & | L, |
const MachineInstr & | MI | ||

Generate a stackmap record for a stackmap instruction.
MI must be a raw STACKMAP, not a PATCHPOINT.

void StackMaps::serializeToStackMapSection | ( | ) |
If there is any stack map data, create a stack map section and serialize the map info into it.
Serialize the stackmap data.
This clears the stack map data structures afterwards.
