This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems".

The branch, master has been updated via bd3eaf83ef1b4954b6c0e7ba8bbdd29b2cd4a833 (commit) via 3f6cd5063abe21992552a17116f5489cbd2021e3 (commit) via 4b03b0db9d9eded088f3c70b4127447f1097de79 (commit) from 077b37591f53a16705a6ddab10bcee80e067ca2f (commit)

Do not define unimplemented functions

e.g. fminf() is not implemented, only fmin(), but both are defined.

cris: remove call to HIDDEN_JUMPTARGET

errno_location is no longer hidden, so remove the call to the macro, like done for sparc recently.

commit 4b03b0db9d9eded088f3c70b4127447f1097de79 Author: Waldemar Brodkorb wbx@openadk.org Date: Fri Sep 26 11:37:02 2014 +0200

cris: do not include asm/elf.h

elf.h is not exported by the Linux kernel, do not include it here. Done like in other architectures.
