We need to build with -mno-pic to disable all uses of GP, as well as use a custom linker script to avoid collisions between klibc.so's and the executable's segments.

Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library

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:

Hi I am writing a freestanding statically linked x86_64 kernel. And now I want to load and use thread-local storage. As I have a freestanding binary I can't use libc/Linux kernel thread-local mechanism and need to implement initialization code by myself. I am trying to find a clear explanation of what is the memory layout for x86 TLS but can't find anything useful. Maybe LLVM developers

Hi, Yes, ldd is generating wrong tbss size. It is just considering one tbss section and not calculating all sections from all objects. The following example on x86_64 shows the issue: --- t0.c --- #include <stdio.h> extern __thread int t0; extern __thread int t1; extern __thread int t2; extern __thread int t3; __thread int t4; __thread int t5; __thread int t6; __thread int t7; int

Hi, I am tracking some TLS issues with lld and found that it is generating wrong tbss size for case where multiple modules have non initialized threads variables. For instance: -- t0.c -- __thread int x0; __thread int x1; __thread int x2; extern __thread int e0; extern __thread int e1; extern __thread int e2; extern __thread int e3; int foo0 () { return x0; } int main () { return x0; }

Building klibc for x86_64 with binutils 2.31 adds an extra .note.gnu.property section to klibc.so, the address of which is not affected by the -Ttext option. Loading a klibc executable then fails with the following kernel log message: 9409 (sh.shared): Uhuuh, elf segment at 0000000000200000 requested but the memory is mapped already I don't exactly see why this is happening, but it is
