Hello, The binaries produced by LLVM and other compilers divide code up into various sections, e.g. the .text section. What is the recommended approach to assigning a symbol the address of a section using LLVM? Using GCC/LD, you can do this with a linker script, e.g. in a linker script you can do: _text = .; _stext = .; These symbols are then available in the corresponding C code using an

Hi, Is the http://xenbits.xensource.com/linux-2.6-xen.hg tree still being updated? if not, what''s the preferred Linux tree to track that has all of the Xen bits? Thanks, Muli _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, as discussed in [1], this series adds a new getprogname module. All it does is providing a getprogname function, much like what is found on e.g. *BSD systems, and using it in gnulib instead of progname. Also, using it explicitly by modules avoids gnulib users the need of either use the progname module (GPL), or to provide program_name (and call set_program_name manually, which is not always

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:
