------- Comment #6 from jakub at gcc dot gnu dot org 2010-03-21 13:26 ------- Found a problem - the patch relies on the fact that the fragments of each block are sorted in ascending order of their PCs, but apparently that is not the case. So how much the patch will actually save on .debug_loc size will show up only when this is fixed.
