plans for gcobol 16

I want to describe what's arriving this fall for the COBOL front end, and check the plan with the august body here assembled. Or, are we compiled? Features pending or planned in 2025: 1. "National" support. COBOL programs define the runtime encoding and collation of each string (sometimes im

Re: Query about configure flags for NVPTX backend

I do not know if we have any "simpler bugs"; you have chosen a hard-mode configuration to work on! You can search gcc.gnu.org/bugzilla for "nvptx" and see if there's anything you'd like to work on. This one is an interesting minor feature to implement, perhaps? https://gcc.gnu.org/bugzilla/s

How to write/read tree contains ssa_name in lto

I used the functions stream_write_tree/stream_read_tree in lto. If tree contains ssa_name, then stream_read_tree will generate ice: cfun is null in wpa, so (*SSANAMES (cfun))[ix] will break the program. How to write/read tree contains ssa_name in lto, e.g., wpa phase? Thanks. ywgrit.

RFC: Debug info for coroutine suspension locations

Hi gcc-devs! TLDR: For debugging C++ coroutines, I patched clang to emit artificial DW_TAG_labels, mapping suspension point ids to the corresponding source location. Looking for alignment re debugging info between clang and gcc. (Finally following up on Iain Sandoe's request to send this email)

Re: How to write/read tree contains ssa_name in lto

A program may consist of multiple compilation units, and multiple array access operations may exist within the program. In SIMPLE_IPA_PASS, I want to check whether the index is consistent during two array accesses: During the first pass through all functions, traverse all gimples, record each array
