toolchain/gcc: enable zstd support

2023-03-17T01:08:25Z

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: remove installing twice in the "initial" subdir

2023-02-19T18:44:39Z

This was apparently introduced to recreate the toolchain (wipe staging_dir/toolchain*, but keep build_dir/toolchain*, followed by a `make toolchain/compile`). But it leaves leftovers and causes re-links to happen at src_install phase, because of the changed paths, possibly adding yet another source of issues. With the prior commits removing various hacks related to the "initial" folder we can remove installing it twice altogether. The recreated toolchain is exactly the same as before.

toolchain/musl: remove libgcc_initial hack

2023-02-19T18:44:39Z

This reverts r15599 [0]. This was added to fix an uclibc rebuild issue, but since uclibc isn't supported anymore [Fixes:] this can be removed.

toolchain/gcc: remove glibc libgcc_eh hack

2023-02-19T18:44:39Z

A modern glibc only links against libgcc_eh for its tests or when building it static, which doesn't happen here. Reverts a hunk of: a3edea1b "add support for alternative C libraries..." Signed-off-by: Andre Heider

toolchain/gcc: clean up CFLAGS

2023-02-09T01:53:35Z

Instead of having two different ways to pass flags to the gcc build process, add them as configure args, which is a reliable way to let gcc pass them around to its various pieces. Also add CXXFLAGS, since gcc started to use c++ for itself recently (~10 years ago now). Signed-off-by: Andre Heider

toolchain/gcc: use explicit configure args

2023-02-09T01:53:35Z

Spell out what we want to enable or disable. This prevents host libs to leak in, so everyone get the same feature set. Signed-off-by: Andre Heider

treewide: strip useless `default n` Kconfig lines

2023-02-03T11:50:15Z

Kconfig docs say: > The default value deliberately defaults to 'n' in order to avoid > bloating the build. Apply this rule everywhere, to avoid more cloning of bad examples Signed-off-by: Tony Butler

toolchain/gcc: use STAGING_DIR_HOST instead of hardcoding default

2023-01-09T20:33:19Z

Use STAGING_DIR_HOST to reference staging host directory instead of hardcoding it to default path. Signed-off-by: Christian Marangi

toolchain/gcc: fix broken gcc version selection

2023-01-09T20:25:30Z

Config evaluation require default with if to be put before the generic default config with no condition. Putting the default config before any conditional default results in always selecting the non conditional one. This results in the version be hardcoded to gcc 12 even if gcc 11 is selected in the Advanced build options. Fix this by putting the gcc 12 default option as last after ANY conditional default config. Fixes: d9de5252a44e ("toolchain/gcc: switch to version 12 by default") Signed-off-by: Christian Marangi

toolchain/gcc: switch to version 12 by default

2023-01-08T23:23:41Z

This was build tested with all core packages on all targets successfully. Most packages from the feed are also building fine. This was run tested on the following systems: * lantiq/xrx200 musl * pistachio/generic musl * sunxi/cortexa53 musl * x86/64 musl * x86/64 glibc * armvirt/64 musl The size of the images stays more or less the same for MIPS BE and aarch64. I haven't tested other architectures. With GCC 11 I got these sizes for lantiq/xrx200: 7,219,848 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin 7,472,208 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin With GCC 12 I got these sizes for lantiq/xrx200: 7,217,355 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin 7,406,674 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin The sysupgrade image is probably padded. The initramfs image is 0.03% smaller. With GCC 11 I got these sizes for armvirt/64: 4,143,943 openwrt-armvirt-64-default-rootfs.tar.gz 10,887,176 openwrt-armvirt-64-Image 24,911,880 openwrt-armvirt-64-Image-initramfs 4,141,572 openwrt-armvirt-64-rootfs.cpio.gz 4,255,854 openwrt-armvirt-64-rootfs-ext4.img.gz 3,391,178 openwrt-armvirt-64-rootfs-squashfs.img.gz With GCC 12 I got these sizes for armvirt/64: 4,142,778 openwrt-armvirt-64-default-rootfs.tar.gz 10,887,176 openwrt-armvirt-64-Image 24,911,880 openwrt-armvirt-64-Image-initramfs 4,138,105 openwrt-armvirt-64-rootfs.cpio.gz 4,255,463 openwrt-armvirt-64-rootfs-ext4.img.gz 3,390,390 openwrt-armvirt-64-rootfs-squashfs.img.gz Signed-off-by: Hauke Mehrtens
