From fe4608386eb163c70a75ed84beb07516af378b36 Mon Sep 17 00:00:00 2001 From: Keith Rothman <537074+litghost@users.noreply.github.com> Date: Fri, 12 Mar 2021 13:09:44 -0800 Subject: Split nextpnr.h to allow for linear inclusion. "nextpnr.h" is no longer the god header. Important improvements: - Functions in log.h can be used without including BaseCtx/Arch/Context. This means that log_X functions can be called without included "nextpnr.h" - NPNR_ASSERT can be used without including "nextpnr.h" by including "nextpnr_assertions.h". This allows NPNR_ASSERT to be used safely in any header file. - Types defined in "archdefs.h" are now available without including BaseCtx/Arch/Context. This means that utility classes that will be used inside of BaseCtx/Arch/Context can be defined safely in a self-contained header.
