From 37caa3d71fd8bb4d0d9204e4a2f5cac234fa25fd Mon Sep 17 00:00:00 2001 From: Tavian Barnes Date: Mon, 29 Apr 2024 15:30:39 -0400 Subject: build: Replace `make config` with a `./configure` script This lets us do more traditional out-of-tree builds like $ ../path/to/bfs/configure $ make The .mk files are moved from ./config to ./build, mostly so that ./configure will auto-complete easily. --- config/flags.mk | 136 -------------------------------------------------------- 1 file changed, 136 deletions(-) delete mode 100644 config/flags.mk (limited to 'config/flags.mk') diff --git a/config/flags.mk b/config/flags.mk deleted file mode 100644 index 837c30f..0000000 --- a/config/flags.mk +++ /dev/null @@ -1,136 +0,0 @@ -# Copyright © Tavian Barnes -# SPDX-License-Identifier: 0BSD - -# Makefile that generates gen/flags.mk - -include config/prelude.mk -include ${GEN}/vars.mk - -# Configurable flags -CPPFLAGS ?= -CFLAGS ?= \ - -g \ - -Wall \ - -Wformat=2 \ - -Werror=implicit \ - -Wimplicit-fallthrough \ - -Wmissing-declarations \ - -Wshadow \ - -Wsign-compare \ - -Wstrict-prototypes -LDFLAGS ?= -LDLIBS ?= - -export XCPPFLAGS=${CPPFLAGS} -export XCFLAGS=${CFLAGS} -export XLDFLAGS=${LDFLAGS} -export XLDLIBS=${LDLIBS} - -# Immutable flags -export BFS_CPPFLAGS= \ - -Isrc \ - -I${GEN} \ - -D__EXTENSIONS__ \ - -D_ATFILE_SOURCE \ - -D_BSD_SOURCE \ - -D_DARWIN_C_SOURCE \ - -D_DEFAULT_SOURCE \ - -D_GNU_SOURCE \ - -D_POSIX_PTHREAD_SEMANTICS \ - -D_FILE_OFFSET_BITS=64 \ - -D_TIME_BITS=64 -export BFS_CFLAGS= -std=c17 -pthread - -# Platform-specific system libraries -LDLIBS,DragonFly := -lposix1e -LDLIBS,Linux := -lrt -LDLIBS,NetBSD := -lutil -LDLIBS,SunOS := -lsec -lsocket -lnsl -export BFS_LDLIBS=${LDLIBS,${OS}} - -# Build profiles -_ASAN := ${TRUTHY,${ASAN}} -_LSAN := ${TRUTHY,${LSAN}} -_MSAN := ${TRUTHY,${MSAN}} -_TSAN := ${TRUTHY,${TSAN}} -_UBSAN := ${TRUTHY,${UBSAN}} -_GCOV := ${TRUTHY,${GCOV}} -_LINT := ${TRUTHY,${LINT}} -_RELEASE := ${TRUTHY,${RELEASE}} - -# https://github.com/google/sanitizers/issues/342 -TSAN_CPPFLAGS,y := -DBFS_USE_TARGET_CLONES=0 -export TSAN_CPPFLAGS=${TSAN_CPPFLAGS,${_TSAN}} - -ASAN_CFLAGS,y := -fsanitize=address -LSAN_CFLAGS,y := -fsanitize=leak -MSAN_CFLAGS,y := -fsanitize=memory -fsanitize-memory-track-origins -TSAN_CFLAGS,y := -fsanitize=thread -UBSAN_CFLAGS.y := -fsanitize=undefined - -export ASAN_CFLAGS=${ASAN_CFLAGS,${_ASAN}} -export LSAN_CFLAGS=${LSAN_CFLAGS,${_LSAN}} -export MSAN_CFLAGS=${MSAN_CFLAGS,${_MSAN}} -export TSAN_CFLAGS=${TSAN_CFLAGS,${_TSAN}} -export UBSAN_CFLAGS=${UBSAN_CFLAGS,${_UBSAN}} - -SAN_CFLAGS,y := -fno-sanitize-recover=all -INSANE := ${NOT,${_ASAN}${_LSAN}${_MSAN}${_TSAN}${_UBSAN}} -SAN := ${NOT,${INSANE}} -export SAN_CFLAGS=${SAN_CFLAGS,${SAN}} - -# MSAN and TSAN both need all code to be instrumented -YESLIBS := ${NOT,${_MSAN}${_TSAN}} -NOLIBS ?= ${NOT,${YESLIBS}} -export XNOLIBS=${NOLIBS} - -# gcov only intercepts fork()/exec() with -std=gnu* -GCOV_CFLAGS,y := -std=gnu17 --coverage -export GCOV_CFLAGS=${GCOV_CFLAGS,${_GCOV}} - -LINT_CPPFLAGS,y := -D_FORTIFY_SOURCE=3 -DBFS_LINT -LINT_CFLAGS,y := -Werror -O2 - -export LINT_CPPFLAGS=${LINT_CPPFLAGS,${_LINT}} -export LINT_CFLAGS=${LINT_CFLAGS,${_LINT}} - -RELEASE_CPPFLAGS,y := -DNDEBUG -RELEASE_CFLAGS,y := -O3 -flto=auto - -export RELEASE_CPPFLAGS=${RELEASE_CPPFLAGS,${_RELEASE}} -export RELEASE_CFLAGS=${RELEASE_CFLAGS,${_RELEASE}} - -# Set a variable -SETVAR = printf '%s := %s\n' >>$@ - -# Append to a variable, if non-empty -APPEND = append() { test -z "$$2" || printf '%s += %s\n' "$$1" "$$2" >>$@; }; append - -${GEN}/flags.mk:: - ${MSG} "[ GEN] ${TGT}" - printf '# %s\n' "${TGT}" >$@ - ${SETVAR} CPPFLAGS "$$BFS_CPPFLAGS" - ${APPEND} CPPFLAGS "$$TSAN_CPPFLAGS" - ${APPEND} CPPFLAGS "$$LINT_CPPFLAGS" - ${APPEND} CPPFLAGS "$$RELEASE_CPPFLAGS" - ${APPEND} CPPFLAGS "$$XCPPFLAGS" - ${APPEND} CPPFLAGS "$$EXTRA_CPPFLAGS" - ${SETVAR} CFLAGS "$$BFS_CFLAGS" - ${APPEND} CFLAGS "$$ASAN_CFLAGS" - ${APPEND} CFLAGS "$$LSAN_CFLAGS" - ${APPEND} CFLAGS "$$MSAN_CFLAGS" - ${APPEND} CFLAGS "$$TSAN_CFLAGS" - ${APPEND} CFLAGS "$$UBSAN_CFLAGS" - ${APPEND} CFLAGS "$$SAN_CFLAGS" - ${APPEND} CFLAGS "$$GCOV_CFLAGS" - ${APPEND} CFLAGS "$$LINT_CFLAGS" - ${APPEND} CFLAGS "$$RELEASE_CFLAGS" - ${APPEND} CFLAGS "$$XCFLAGS" - ${APPEND} CFLAGS "$$EXTRA_CFLAGS" - ${SETVAR} LDFLAGS "$$XLDFLAGS" - ${SETVAR} LDLIBS "$$XLDLIBS" - ${APPEND} LDLIBS "$$EXTRA_LDLIBS" - ${APPEND} LDLIBS "$$BFS_LDLIBS" - ${SETVAR} NOLIBS "$$XNOLIBS" - test "${OS}-${SAN}" != FreeBSD-y || printf 'POSTLINK = elfctl -e +noaslr $$@\n' >>$@ - ${VCAT} $@ -- cgit v1.2.3
