This is especially needed for obj-pbl-y code as the files usually have other functions depending on barebox proper infrastructure, but that is never called. This works so far, but breaks for two things: LTO and using PBL on sandbox. Both I have not managed to get the linker not to complain about the undefined references in the ultimately unreferenced code. Therefore, let's solve this a different way: Adjust the relevant headers to define stubs when built for sandbox. This has the nice side effect of compile testing the stubs during PBL build, so forgotten semicolons are more likely to be noticed during development instead of CI run. v1 -> v2: - squash fixes noticed by CI (strerror, PBL_CONSOLE) - define printk/BUG for host tools to fix compile error - replace IS_PROPER macro with new global IN_PROPER macro - use IN_PROPER where appropriate Ahmad Fatoum (16): scripts: include: add definitions for printk and BUG() xfuncs: include for free definition pbl: define IN_PBL & IN_PROPER macros globally treewide: replace inverted check for PBL with new IN_PROPER macro lib: random: add stubs for PBL bootsource: stub out when in PBL crypto: provide crypto_memneq for PBL cdev: stub out cdev_read/write for PBL libfile: stub out file descriptor API for PBL environment: stub out environment API for PBL of: stub out live tree API when using PBL errno: stub out perror/strerror API when built for PBL xfuncs: stub out API when built for PBL stdio: stub out basprintf and friends when built for PBL memory: stub out request_barebox_region for PBL malloc: add PBL stubs arch/arm/mach-imx/romapi.c | 2 +- arch/arm/mach-omap/omap3_generic.c | 2 +- arch/riscv/include/asm/unwind.h | 2 +- common/bootsource.c | 2 +- crypto/Makefile | 2 +- drivers/pinctrl/imx-iomux-v1.c | 2 +- fs/fat/ff.h | 2 +- include/abort.h | 2 +- include/dma.h | 2 +- include/driver.h | 24 +++++++++- include/environment.h | 2 +- include/errno.h | 10 +++++ include/fcntl.h | 8 ++++ include/libfile.h | 7 +++ include/linux/iopoll.h | 4 +- include/linux/kasan.h | 2 +- include/linux/kconfig.h | 8 ++++ include/linux/list.h | 2 +- include/linux/printk.h | 4 +- include/linux/string.h | 7 +++ include/malloc.h | 37 +++++++++++++++ include/memory.h | 10 +++++ include/of.h | 2 +- include/pbl.h | 6 --- include/printk.h | 4 +- include/stdio.h | 28 ++++++++++-- include/stdlib.h | 19 +++++++- include/unistd.h | 72 ++++++++++++++++++++++++++++++ include/xfuncs.h | 20 +++++++++ include/zero_page.h | 2 +- lib/vsprintf.c | 4 +- scripts/include/asm-generic/bug.h | 14 ++++++ scripts/include/linux/bug.h | 1 + scripts/include/printk.h | 9 ++++ 34 files changed, 289 insertions(+), 35 deletions(-) create mode 100644 scripts/include/asm-generic/bug.h create mode 100644 scripts/include/linux/bug.h create mode 100644 scripts/include/printk.h -- 2.39.5
