From: Michael Davidson <md at google.com> Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Don't use -nostdinc when building klibc. While klibc doesn't (shouldn't) use the standard header files supplied by the toolchain, it does still need to be able to find the compiler-specific header file

Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Use "--print-file-name=include" and "--print-libgcc-file-name" when using clang. Use cc-option to enable compiler-specific flags. Mark "bcmp" as not a builtin to prevent clang from using it. Signed-off-by: Bill Wendling <morbo at google.com>

This is a klibc port to x32 architecture. I tried to reuse as many existing files as possible, hence, a script making symlinks to x86-64 files. I was running this on Debian for about six months and hopefully, found any close to surface bugs. Of course, there are plenty left. Please help with testing. To build you need to run: make ARCH=x32 Makefile | 15 ++--

Hello ppc32 users, I think I finally got the "official" answer on the ppc32 problem. Apparently some distributions build binutils so that it defaults to elf32ppc emulation rather than elf32ppclinux. This doesn't matter when using gcc, since gcc overrides the emulation explicitly, but it does matter when invoking ld directly like klibc does. This patch should hopefully take

When using clang+llvm and lld, I get the following error: ld.lld: error: -Ttext-segment is not supported. Use --image-base if you intend to set the base address Let's test whether linker is lld and use --image-base instead of -Ttext-segment. See llvm's rationale for not supporting -Ttext-segment: https://github.com/llvm/llvm-project/commit/4dc2fb123dcfe9a97ad6f3a1135053b74efd0bc9 Note

In the v3.6 kernel, many of the headers were split out into a uapi variant. klibc should be using those variants to compile. There is also a generated subdir, to seperate out generated headers. The old kernel header location needs to be included as well, because linux/compiler.h is available only in the base include directory. Signed-off-by: Robin H. Johnson <robbat2 at gentoo.org> ---
