From cdae8d0559d41f9464ab54e2967e23a0ee06a358 Mon Sep 17 00:00:00 2001 From: Marc Poulhiès Date: Tue, 13 Dec 2022 21:16:22 +0100 Subject: Enable support for building libgccjit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit libgccjit is still under development and, despite its name, may also be used for ahead-of-time compilation. Documentation can be found on the gcc website: https://gcc.gnu.org/onlinedocs/jit/internals/index.html https://gcc.gnu.org/wiki/JIT With this change it's possible to enable the building of the libgccjit. It's enabled as a language (with --enable-languages=jit) even if not a language frontend at all. The main changes are related to the requirement of having everything host side built as Position Independent Code (PIC) with --enable-host-shared. GCC has the needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when built "in-tree", which is not the case with crosstool-ng (see https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0) Signed-off-by: Marc Poulhiès --- scripts/build/cc/gcc.sh | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'scripts/build/cc') diff --git a/scripts/build/cc/gcc.sh b/scripts/build/cc/gcc.sh index 1d7fc065..18558533 100644 --- a/scripts/build/cc/gcc.sh +++ b/scripts/build/cc/gcc.sh @@ -45,6 +45,7 @@ cc_gcc_lang_list() { [ "${CT_CC_LANG_ADA}" = "y" ] && lang_list+=",ada" [ "${CT_CC_LANG_D}" = "y" ] && lang_list+=",d" [ "${CT_CC_LANG_JAVA}" = "y" ] && lang_list+=",java" + [ "${CT_CC_LANG_JIT}" = "y" ] && lang_list+=",jit" [ "${CT_CC_LANG_OBJC}" = "y" ] && lang_list+=",objc" [ "${CT_CC_LANG_OBJCXX}" = "y" ] && lang_list+=",obj-c++" [ "${CT_CC_LANG_GOLANG}" = "y" ] && lang_list+=",go" @@ -343,6 +344,10 @@ do_gcc_core_backend() { extra_config+=("--enable-newlib-nano-formatted-io") fi + if [ "${CT_CC_LANG_JIT}" = "y" ]; then + extra_config+=("--enable-host-shared") + fi + if [ "${CT_CC_CXA_ATEXIT}" = "y" ]; then extra_config+=("--enable-__cxa_atexit") else -- cgit v1.2.3
