tools: Patch libtool to pass-through sanitizer flags This is a backport of http://git.savannah.gnu.org/cgit/libtool.git/commit/?id=a5c6466 as libtool has no release that includes this commit, yet. It fixes using sanitizers on macOS, as without this patch, the relevant flag is not passed to the compiler when linking, causing undefined symbol errors. > http://git.videolan.org/gitweb.cgi/vlc.git/?a=commit;h=705bbb20a6f461530a603fe428fa30165e1b6594 --- extras/tools/libtool-2.4.2-san.patch | 44 ++++++++++++++++++++++++++++++++++++ extras/tools/tools.mak | 1 + 2 files changed, 45 insertions(+) diff --git a/extras/tools/libtool-2.4.2-san.patch b/extras/tools/libtool-2.4.2-san.patch new file mode 100644 index 0000000000..4f833aac60 --- /dev/null +++ b/extras/tools/libtool-2.4.2-san.patch @@ -0,0 +1,44 @@ +From a5c6466528c060cc4660ad0319c00740db0e42ba Mon Sep 17 00:00:00 2001 +From: Jeremy Huddleston Sequoia <[email protected]> +Date: Sun, 18 Oct 2015 21:55:39 -0700 +Subject: libtool: fix GCC/clang linking with -fsanitize=* + +References: +https://lists.gnu.org/archive/html/libtool/2014-04/msg00026.html + +* build-aux/ltmain.in (func_mode_link): Pass -fsanitize=* to the +linker to allow trivial use of the clang address sanitizer. + +Signed-off-by: Jeremy Huddleston Sequoia <[email protected]> +Copyright-paperwork-exempt: Yes +--- +diff -ru libtool/libltdl/config/ltmain.m4sh libtool-fixed/libltdl/config/ltmain.m4sh +--- libtool/libltdl/config/ltmain.m4sh 2017-10-16 08:20:47.000000000 +0200 ++++ libtool-fixed/libltdl/config/ltmain.m4sh 2017-10-16 08:22:23.000000000 +0200 +@@ -5064,9 +5064,10 @@ + # -tp=* Portland pgcc target processor selection + # --sysroot=* for sysroot support + # -O*, -flto*, -fwhopr*, -fuse-linker-plugin GCC link-time optimization ++ # -fsanitize=* Clang/GCC memory and address sanitizer + -64|-mips[0-9]|-r[0-9][0-9]*|-xarch=*|-xtarget=*|+DA*|+DD*|-q*|-m*| \ + -t[45]*|-txscale*|-p|-pg|--coverage|-fprofile-*|-F*|@*|-tp=*|--sysroot=*| \ +- -O*|-flto*|-fwhopr*|-fuse-linker-plugin) ++ -O*|-flto*|-fwhopr*|-fuse-linker-plugin|-fsanitize=*) + func_quote_for_eval "$arg" + arg="$func_quote_for_eval_result" + func_append compile_command " $arg" +diff -ru libtool/libltdl/config/ltmain.sh libtool-fixed/libltdl/config/ltmain.sh +--- libtool/libltdl/config/ltmain.sh 2017-10-16 08:20:47.000000000 +0200 ++++ libtool-fixed/libltdl/config/ltmain.sh 2017-10-16 08:22:58.000000000 +0200 +@@ -5851,9 +5851,10 @@ + # -tp=* Portland pgcc target processor selection + # --sysroot=* for sysroot support + # -O*, -flto*, -fwhopr*, -fuse-linker-plugin GCC link-time optimization ++ # -fsanitize=* Clang/GCC memory and address sanitizer + -64|-mips[0-9]|-r[0-9][0-9]*|-xarch=*|-xtarget=*|+DA*|+DD*|-q*|-m*| \ + -t[45]*|-txscale*|-p|-pg|--coverage|-fprofile-*|-F*|@*|-tp=*|--sysroot=*| \ +- -O*|-flto*|-fwhopr*|-fuse-linker-plugin) ++ -O*|-flto*|-fwhopr*|-fuse-linker-plugin|-fsanitize=*) + func_quote_for_eval "$arg" + arg="$func_quote_for_eval_result" + func_append compile_command " $arg" diff --git a/extras/tools/tools.mak b/extras/tools/tools.mak index c52e6ec8eb..d96cc837e8 100644 --- a/extras/tools/tools.mak +++ b/extras/tools/tools.mak @@ -86,6 +86,7 @@ libtool-$(LIBTOOL_VERSION).tar.gz: libtool: libtool-$(LIBTOOL_VERSION).tar.gz $(UNPACK) $(APPLY) libtool-2.4.2-bitcode.patch + $(APPLY) libtool-2.4.2-san.patch $(MOVE) .libtool: libtool .automake _______________________________________________ vlc-commits mailing list [email protected] https://mailman.videolan.org/listinfo/vlc-commits
