Hi all, I recently ran into some discussion with Jakub about using std::string in gfortran (see PR 78822), which got me curious about some general points ...
What I'd like to know is: In the current state of things in GCC, is it possible/reasonable to use any of the STL containers (like std::vector, std::string, whatever) in GCC and its front ends (in particular gfortran)? That question has two parts: 1) Is it technically possible at all? Are there drawbacks/pitfalls? (In particular Jakub mentioned possible memory management issues, i.e. xmalloc vs malloc etc.) 2) If technically possible, is it encouraged? I didn't find any statement about STL in the GCC coding conventions (https://gcc.gnu.org/codingconventions.html). Looking through the current GCC code base, it seems that mostly the Go FE is making extensive use of the things like std::string and std::vector, while other parts only use such things rarely. Basically the only STL construct used in the Fortran FE right now seems to be std::swap, and a single instance of std::map in trans-common.c. Would there be a general problem with using std::string in gfortran? Cheers, Janus
