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>

while this doesn't fix the problem that shared doesn't work there, it at least ensures that klibc.so and (e.g.) sh.shared do not try to occupy the same virtual addresses mips64 is also missing KLIBCSHAREDFLAGS and needs treatment Signed-off-by: Thorsten Glaser <tg at mirbsd.org> --- usr/klibc/arch/ia64/MCONFIG | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/usr/klibc/arch/ia64/MCONFIG b/usr/klibc/arch/ia64/MCONFIG index ad868ef..5b2eac6 100644 --- a/usr/klibc/arch/ia64/MCONFIG...

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:

Dear experts, I'm new in klibc and currently studying the source codes. I'm looking at the codes in usr/klibc/arch and can't figure out why does, e.g. in x86_64, the text segment offset differ from system v x86_64 abi (which is 4 Mb)? How does this value was calculated? Thanks in advance! Nikita.

- 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

...ode at 0x400000. Seems that the increased maximum page size is just for better performance, and the value can be decreased without losing compatibility. New ld versions have an option for this: -z max-page-size=SIZE Set maximum page size to SIZE Adding "-z max-page-size=0x100000" to KLIBCSHAREDFLAGS fixes klibc.so build on new binutils - the resulting binaries run fine even on kernels with the exec-shield patch. Probably this option can even be added unconditionally - GNU ld silently ignores all "-z KEYWORD" options which it does not understand, therefore the added options should n...

We currently use KLIBCKERNELSRC and KLIBCKERNELOBJ variables which used to be required to point to a kernel source and object directories. However the kernel headers were reorganised starting in Linux 3.7 such that that doesn't work properly. This series removes KLIBCKERNELOBJ and changes the use and documentation of KLIBCKERNELSRC to be consistent. Ben. Ben Hutchings (4): [klibc]
