From 76c4ee4ea5cb6a3dc214f66237af22a1bedda010 Mon Sep 17 00:00:00 2001 From: whitequark Date: Wed, 3 Jun 2020 00:12:54 +0000 Subject: [PATCH] techmap, flatten: remove dead options. After splitting the passes, some options can never be activated, and most conditions involving them become dead. Remove them, and also all of the newly dead code. --- passes/techmap/flatten.cc | 747 +++----------------------------------- passes/techmap/techmap.cc | 403 +++++++++----------- 2 files changed, 217 insertions(+), 933 deletions(-) diff --git a/passes/techmap/flatten.cc b/passes/techmap/flatten.cc index b0c8ea907..214cda844 100644 --- a/passes/techmap/flatten.cc +++ b/passes/techmap/flatten.cc @@ -20,21 +20,11 @@ #include "kernel/yosys.h" #include "kernel/utils.h" #include "kernel/sigtools.h" -#include "libs/sha1/sha1.h" #include #include #include -#include "simplemap.h" - -YOSYS_NAMESPACE_BEGIN - -// see maccmap.cc -extern void maccmap(RTLIL::Module *module, RTLIL::Cell *cell, bool unmap = false);
