--- Comment #29 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 55031 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55031 WIP patch for a dynamic int_range<> What I meant is that by using a auto_vec could avoid reimplementing larger chunks of vec.h/vec.cc for this. Resizing by adding 10 more ranges can have higher compile time cost than what vec.cc (calculate_allocation_1) does - doubles the size each time for smaller sizes and and multiplying previous by 3 / 2 for larger ones.
