--- Comment #2 from qinzhao at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #1) > The size limitation is given from the way columns, lines, blocks and > location ranges are encoded in location_t, which is a 32-bit number. > See libcpp/include/line-map.h comment above location_t typedef. > If you have very long lines (I think more than 4095 columns), the code is > badly formatted and -Wmisleading-indentation just doesn't make sense. does this mean, for a 32-bit number, the size limitation cannot be changed anymore? if we use 64-bit number for it, will that resolve the issue?
