From: Sylvain Gault <sylvain.gault at gmail.com> These patches basically remove unused linker scripts and port a change that was made to an unused script. Those are to be applied on top of the gcc 5 bug fixes as they would conflict otherwise.

The PE headers of the generated efi file were quite buggy. And since OVMF perform a few consistency checks, syslinux was unable to run on it. I don't pretend to have a thorough understanding of the PE+ headers, some bugs may remain. :) Celelibi (4): efi: Fix PE header field rva_and_sizes_nr efi: Location, size and alignment of .text section efi: Useless relocations in PE file efi: PE

This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between

Hi, I am writing a function that clears the BSS section on an Cortex-M4 embedded system. The LLVM (version 3.7.0rc3) code I had wrote is : ;------------ target datalayout = "e-m:e-p:32:32-i64:64-v128:64:128-a:0:32-n32-S64" target triple = "thumbv7em-none--eabi" @__bss_start = external global i32 @__bss_end = external global i32 define void @clearBSS () nounwind { entry:

I want to share a little LLVM experiment. I tried LLVM on one of my bigger Qt 3.x based projects. I used llvm from SVN trunk (r39999) and SVN llvm-gcc-4.01 (r370) and did compile every file with /usr/src/llvm/dist/bin/g++ -c -pipe -g \ -Wall -Wextra -Wno-sign-compare \ ... lots of -Dxxxx ... \ --emit-llvm -I/usr/share/qt3/mkspecs/default \ -I. -I.. -I../../../include/qt3 -I.obj/ \

This series: 1. Updates the boot protocol to version 2.07 2. Clean up the existing build process, to get rid of tools/build and make the linker do more heavy lifting 3. Make the bzImage payload an ELF file. The bootloader can extract this as a naked ELF file by skipping over boot_params.setup_sects worth of 16-bit setup code. 4. Update the boot_params to 2.07, and update the

Hi Holger, > Note that I did specify "-g", but not any "-Ox" switches. That > made the size of all *.o files together being 143 MB. LLVM represents debug info as explicit calls to intrinsics. This approach has many advantages, but a possible disadvantage is that it can significantly increase the size of the bitcode. I don't know if that explains your observations.

Hi Jim, Yes, the relocation entries have to be reordered so that the got16/lo16 or hi16/lo16 pairs appear consecutively in the relocation table. As a result, relocations can appear in a different order than the instructions that they're for. For example, in this code, the post-RA scheduler inserts an instruction with relocation %got(body_ok) between %got(scope_top) and %lo(scope_top). $ cat

Hi, I hope I''m right here. If not then please point me in the right direction. My problem in short: I have problems using (pinning, mmu_update) physical pages from 0x900000 to 0xB1000 usualy. I''m writing my own little amd64 64bit toy kernel (based on Mini-OS as starting point) for xen and I run into problems with the way the start of day sets up the physical pages. My kernel

[ This patch depends on the cross-architecture ELF cleanup patch. ] This series updates the boot protocol to 2.07 and uses it to implement paravirtual booting. This allows the bootloader to tell the kernel what kind of hardware/pseudo-hardware environment it's coming up under, and the kernel can use the appropriate boot sequence code.

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.
