From 9f34b60a43db147aa186ac97d9d6fc4cde7d4a3d Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 22 Feb 2021 00:51:34 -0500 Subject: [PATCH] sim: igen: drop config.h & header checking While the configure script was checking for a bunch of headers, only one of them was conditionally included in the source (unistd.h). The rest were always included. Based on those usage this whole time, we can reasonably assume that the build also has unistd.h. All the other files including config.h never actually used any defines from the header. --- sim/igen/ChangeLog | 14 + sim/igen/Makefile.in | 9 +- sim/igen/config.in | 64 --- sim/igen/configure | 1074 ++-------------------------------------- sim/igen/configure.ac | 9 +- sim/igen/filter.c | 3 - sim/igen/filter_host.c | 1 - sim/igen/igen.c | 1 - sim/igen/lf.c | 1 - sim/igen/misc.c | 1 - sim/igen/misc.h | 3 - sim/igen/table.c | 3 - 12 files changed, 58 insertions(+), 1125 deletions(-) delete mode 100644 sim/igen/config.in diff --git a/sim/igen/ChangeLog b/sim/igen/ChangeLog index 69af85dc267..1141db94657 100644 --- a/sim/igen/ChangeLog +++ b/sim/igen/ChangeLog @@ -1,3 +1,17 @@ +2021-02-28 Mike Frysinger + + * Makefile.in (filter_filename.o): Delete unused target. + (distclean): Remove config.h. + (config.h, stamp-h): Delete targets. + * configure.ac (AC_CONFIG_HEADER): Delete call. + (AC_CHECK_HEADERS, AC_HEADER_DIRENT): Likewise. + (AC_OUTPUT): Remove 2nd arg. + * filter.c: Remove config.h include. + * filter_host.c, igen.c, lf.c, misc.c, misc.h: Likewise. + * table.c: Likewise.
