◆ 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.

◆ comesBefore()
| bool Instruction::comesBefore | ( | const Instruction * | Other | ) | const |
Given an instruction Other in the same basic block as this instruction, return true if this instruction comes before Other.
In this worst case, this takes linear time in the number of instructions in the block. The results are cached, so in common cases when the block remains unmodified, it takes constant time.
