[libc] Template the writing mode for the writer class (#111559) 2025-03-12T18:51:44+00:00 Joseph Huber huberjn@outlook.com 2025-03-12T18:51:44+00:00 598e882ee88a1e3349fb6d8dcd68f6d3b1c6334f Summary: Currently we dispatch the writing mode off of a runtime enum passed in by the constructor. This causes very unfortunate codegen for the GPU targets where we get worst-case codegen because of the unused function pointer for `sprintf`. Instead, this patch moves all of this to a template so it can be masked out. This results in no dynamic stack and uses 60 VGPRs instead of 117. It also compiles about 5x as fast.
