similar to: [klibc:master] Kbuild: Enable full debug information

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>

New clang versions need the '-ffreestanding' flag because new changes convert system calls to their unlocked versions, which don't exist in the kernel library.

This reverts commit 9d8d648e604026b32cad00a84ed6c29cbd157641, which broke signal handing on some architectures. On m68k and parisc, signal return depends on a trampoline that the kernel writes on the stack. On alpha, s390, and sparc (32-bit), we can avoid this by providing our own function as sa_restorer, but we currently don't. Signed-off-by: Ben Hutchings <ben at decadent.org.uk>

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

hello hpa, here my birthday submission :) please pull: git pull git://git.debian.org/users/maks/klibc.git maks Sam fixed a longstanding x86_32 build bug, thus it seems a good time to flush the queue of the piled up patches, the shortlog tells it: Aurelien Jarno (1): [klibc] sh4: syscalls fixes Benjamin Cama (1): [klibc] fstype: btrfs size endianness fix Mike Waychison (2):

- 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

Clang doesn't have a suitable replacement for libgcc readily available. Supply one that we know exists. Use "-fno-builtin-bcmp" to prevent clang from calling a function that doesn't exist.
