We don't define many of them, and adding a lot of -fno-builtin-* options to inhibit this seems like a losing battle. Since we don't support multi-threaded...

Add virtio_gpu_queue_ctrl_buffer_nolock function, which does the same as virtio_gpu_queue_ctrl_buffer but does not take the virtqueue lock. The caller must hold the lock instead.

...rnel.org/pub/scm/libs/klibc/klibc.git and as a tarball at: https://mirrors.kernel.org/pub/linux/libs/klibc/2.0/ New features: - Support for building with clang and lld, at least on x86 - Defined sysconf(), initially supporting only _SC_PAGE_SIZE - Defined clearerr() as extern - Defined stdio _unlocked functions and macros - Support for building without bash Bug fixes: - Fix build regression with gcc 10 - Executable stacks are disabled on architectures where they are not needed - fstype no longer checks whether an ext4 module is installed, which did not work correctly with compressed modules...

Clang is now optimising some stdio calls to their _unlocked variants, which we don't define. I added definitions of all those, and was then able to able to build everything with Clang and ld.bfd. I've pushed that change following these patches. However, when I use Clang and ld.lld, it fails to link dynamically- linked programs: ld.lld: error...

I'll change it. cheers, Gerd

- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that cause warnings. - Retain
