This fixes a segmentation fault in the system call's error handling path with dynamically-linked binaries on PowerPC64 little endian. The system call stub wasn't loading up r2 with the appropriate TOC value in its global entry point. The r2 setup code comes from the FUNC_START macro in gcc [1] and an equivalent one can also be found in the LOCALENTRY macro in glibc [2]. On the ELFv2 ABI

Based on work by Neil Williams (codehelp at debian.org) and Anil Singhar (anil.singhar at linaro.org), this patch introduces arm64 support. Signed-off-by: Steve Capper <steve.capper at linaro.org> --- Makefile | 3 +- usr/include/arch/arm64/klibc/archconfig.h | 17 ++++++++++ usr/include/arch/arm64/klibc/archsetjmp.h | 20 ++++++++++++

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:

If available, use -mcmodel=small. klibc is small enough that we should never hit the limits of the small memory model. This produces better code, for example: 000000000f003890 <.strcasecmp>: f003890: 3c a2 ff fe addis r5,r2,-2 ... f003898: 38 c5 23 58 addi r6,r5,9048 ... f0038ac: 7d 46 50 ae lbzx r10,r6,r10 vs: 000000000f0037c4 <.strcasecmp>:

- 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

klibc now runs on the CRIS archtitecture. The patch below is against 0.146. Most of the changes are trivial but the new files in libgcc requires some comments. __negdi2.c: The CRIS port fallbacks to C-code for negdi2. The code in __negdi2.c is copied from libgcc2.c but with modified typenames. I would really appreciate if someone could check if it seams sane. crisarith.c: CRIS has no built-in

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>

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.
