◆ applyMergedLocation()
| void Instruction::applyMergedLocation | ( | const DILocation * | LocA, |
| const DILocation * | LocB | ||
| ) |
Merge 2 debug locations and apply it to the Instruction.
If the instruction is a CallIns, we need to traverse the inline chain to find the common scope. This is not efficient for N-way merging as each time you merge 2 iterations, you need to rebuild the hashmap to find the common scope. However, we still choose this API because: 1) Simplicity: it takes 2 locations instead of a list of locations. 2) In worst case, it increases the complexity from O(N*I) to O(2*N*I), where N is # of Instructions to merge, and I is the maximum level of inline stack. So it is still linear. 3) Merging of call instructions should be extremely rare in real applications, thus the N-way merging should be in code path. The DebugLoc attached to this instruction will be overwritten by the merged DebugLoc.
