From acc8c2d829fb5e0e0b2495d720e058f91ea164b0 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Sun, 5 Feb 2023 23:21:46 +0100 Subject: [PATCH] toolchain/gcc: enable zstd support LTO object files will now be compressed using zstd. Compressing debug sections with zstd will have to wait for GCC 13, which adds support for -gz=zstd. NOTE: wiping the ccache is strongly recommended, not doing so might yield build error later on: "lto1: internal compiler error: original not compressed with zstd" Signed-off-by: Andre Heider --- toolchain/gcc/common.mk | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/toolchain/gcc/common.mk b/toolchain/gcc/common.mk index e885141538..25f7e1ef70 100644 --- a/toolchain/gcc/common.mk +++ b/toolchain/gcc/common.mk @@ -66,6 +66,9 @@ TAR_OPTIONS += \ --exclude-from='$(CURDIR)/../exclude-testsuite' --exclude=gcc/ada/*.ad* \ --exclude=libjava +# this needs to be without -L/-lzstd flags or other parts fail to build +# use an absolute path to ensure it really picks up our version +export ac_cv_search_ZSTD_compress=$(STAGING_DIR_HOST)/lib/libzstd.a -pthread export libgcc_cv_fixed_point=no ifdef CONFIG_INSTALL_GCCGO export libgo_cv_c_split_stack_supported=no @@ -103,7 +106,7 @@ GCC_CONFIGURE:= \ $(if $(CONFIG_arc),--with-cpu=$(CONFIG_CPU_TYPE)) \ $(if $(CONFIG_powerpc64), $(if $(CONFIG_USE_MUSL),--with-abi=elfv2)) \ --with-system-zlib=$(STAGING_DIR_HOST) \ - --without-zstd \ + --with-zstd=$(STAGING_DIR_HOST) \ --with-gmp=$(STAGING_DIR_HOST) \ --with-mpfr=$(STAGING_DIR_HOST) \ --with-mpc=$(STAGING_DIR_HOST) \
