bb5f7016 - kernel: Add defination of .init_array and .fini_array for all other platforms

Mon, 02 Sep 2024 04:26:48 +0000

kernel: Add defination of .init_array and .fini_array for all other platformsCurrently these sections are not used but defined only for amd64 andi386. Added them for all other platforms to keep all platforms in sync.There should be no functional change.This change is extracted from a bigger patch [1] of hselasky, withadditional fix for the order of .fini_array section.1. https://reviews.freebsd.org/D40467Obtained from: hselaskyMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D45214(cherry picked from commit 3e76d05231b0aa77d922bdbc9abf62d9747a91ab) List of files: /freebsd-14.2/sys/conf/ldscript.powerpc

9411e24d - [PowerPC] kernel ifunc support for powerpc*, fix ppc64 relocation oddities.

Thu, 07 May 2020 19:32:49 +0000

[PowerPC] kernel ifunc support for powerpc*, fix ppc64 relocation oddities.This is a general cleanup of the relocatable kernel support on powerpc,needed to enable kernel ifuncs. * Fix some relocatable issues in the kernel linker, and change to using a RELOCATABLE_KERNEL #define instead of #ifdef __powerpc__ for parts that other platforms can use in the future if they wish to have ET_DYN kernels. * Get rid of the DB_STOFFS hack now that the kernel is relocated to the DMAP properly across the board on powerpc64. * Add powerpc64 and powerpc32 ifunc functionality. * Allow AIM64 virtual mode OF kernels to run from the DMAP like other AIM64 by implementing a virtual mode restart. This fixes the runtime address on PowerMac G5. * Fix symbol relocation problems on post-relocation kernels by relocating the symbol table. * Add an undocumented method for supplying kernel symbols on powernv and other powerpc machines using linux-style kernel/initrd loading -- If you pass the kernel in as the initrd as well, the copy resident in initrd will be used as a source for symbols when initializing the debugger. This method is subject to removal once we have a better way of doing this.Approved by: jhibbitsRelnotes: yesSponsored by: Tag1 Consulting, Inc.Differential Revision: https://reviews.freebsd.org/D23156 List of files: /freebsd-14.2/sys/conf/ldscript.powerpc

6d515b0c - powerpc: Kernel fixes for ppc32 and powerpcspe w/ lld

Thu, 14 Nov 2019 04:34:17 +0000

powerpc: Kernel fixes for ppc32 and powerpcspe w/ lldFix wrong section ordering that was causing a ".got is not contiguous withother relro sections" lld error. This also brings ldscript.powerpc andldscript.powerpcspe closer to ldscript.powerpc64.Also, remove unnecessary text relocs from the ppc32 AIM trap code.Approved by: jhibbits (mentor)Differential Revision: https://reviews.freebsd.org/D22349 List of files: /freebsd-14.2/sys/conf/ldscript.powerpc

45eff3df - remove CONSTRUCTORS from kernel linker scripts

Thu, 28 Jul 2016 13:54:46 +0000

remove CONSTRUCTORS from kernel linker scriptsThe linker script CONSTRUCTORS keyword is only meaningful "when linkingobject file formats which do not support arbitrary sections, such asECOFF and XCOFF"[1] and is ignored for other object file formats.LLVM's lld does not yet accept (and ignore) CONSTRUCTORS, so just removeCONSTRUCTORS from the linker scripts as it has no effect.[1] https://sourceware.org/binutils/docs/ld/Output-Section-Keywords.htmlReviewed by: kibSponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D7343 List of files: /freebsd-14.2/sys/conf/ldscript.powerpc

Fri, 10 Oct 2014 06:24:09 +0000

Rename elf*-powerpc into elf*-powerpc-freebsd in binutilsThe powerpc support was the only supported architecture not prepending the elf format namewith "-freebsd" in base this change makes it consistent with other architectures.On newer version of binutils the powerpc format is also prepended with "-freebsd".Also modify the kernel ldscripts in that regards.As a result it is now possible cross build the kernel on powerpc using newer binutilsDifferential Revision: https://reviews.freebsd.org/D926Differential Revision: https://reviews.freebsd.org/D928 List of files: /freebsd-14.2/sys/conf/ldscript.powerpc
