This is a series of patches for clang compatibility: - Using flags needed flags and removing unsupported flags. - Adding support for clang's LLD linker. - Removing a variety of warnings. Bill Wendling (3): [klibc] Kbuild: use "libc.a" with clang [klibc] Kbuild: Add "-fcommon" for clang builds [klibc] Clean up clang warnings Michael Davidson (1): [klibc] Kbuild:

- 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

The following patchset implements 3 seperate series of changes. External Building ================= Patches 1 through 8 enable to use of klibc's build system while leaving the src tree pristine (and potentially read only). Specifically: - srctree=<Sources for klibc> - objtree=<Ouput directory for klibc> - KLIBCKERNELSRC=<Kernel sources> - KLIBCKERNELOBJ=<Kernel

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:
