The branch stable/14 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=bb5f701614546c2e2cc682e23f49f7606cea3138 commit bb5f701614546c2e2cc682e23f49f7606cea3138 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2024-09-02 04:26:48 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2024-09-22 14:45:36 +0000 kernel: Add defination of .init_array and .fini_array for all other platforms Currently these sections are not used but defined only for amd64 and i386. 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, with additional fix for the order of .fini_array section. 1. https://reviews.freebsd.org/D40467 Obtained from: hselasky MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D45214 (cherry picked from commit 3e76d05231b0aa77d922bdbc9abf62d9747a91ab) --- sys/conf/ldscript.arm | 14 ++++++++++++++ sys/conf/ldscript.arm64 | 14 ++++++++++++++ sys/conf/ldscript.powerpc | 16 ++++++++++++++-- sys/conf/ldscript.powerpc64 | 15 ++++++++++++++- sys/conf/ldscript.powerpc64le | 15 ++++++++++++++- sys/conf/ldscript.powerpcspe | 16 ++++++++++++++-- sys/conf/ldscript.riscv | 14 ++++++++++++++ 7 files changed, 98 insertions(+), 6 deletions(-) diff --git a/sys/conf/ldscript.arm b/sys/conf/ldscript.arm index a9c39977a6fc..f42af5bc4a4c 100644 --- a/sys/conf/ldscript.arm +++ b/sys/conf/ldscript.arm @@ -83,6 +83,20 @@ SECTIONS } .data1 : { *(.data1) } . = ALIGN(32 / 8); + .init_array : + { + PROVIDE_HIDDEN (__init_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.init_array.*))) + KEEP (*(.init_array)) + PROVIDE_HIDDEN (__init_array_end = .); + } + .fini_array : + { + PROVIDE_HIDDEN (__fini_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.fini_array.*))) + KEEP (*(.fini_array)) + PROVIDE_HIDDEN (__fini_array_end = .); + } _start_ctors = .; PROVIDE (start_ctors = .); .ctors : diff --git a/sys/conf/ldscript.arm64 b/sys/conf/ldscript.arm64 index 21c7dc35d9b7..8a4aeebb6622 100644 --- a/sys/conf/ldscript.arm64 +++ b/sys/conf/ldscript.arm64 @@ -98,6 +98,20 @@ SECTIONS . = ALIGN(128); .data1 : { *(.data1) } . = ALIGN(32 / 8); + .init_array : + { + PROVIDE_HIDDEN (__init_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.init_array.*))) + KEEP (*(.init_array)) + PROVIDE_HIDDEN (__init_array_end = .); + } + .fini_array : + { + PROVIDE_HIDDEN (__fini_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.fini_array.*))) + KEEP (*(.fini_array)) + PROVIDE_HIDDEN (__fini_array_end = .); + } _start_ctors = .; PROVIDE (start_ctors = .); .ctors : diff --git a/sys/conf/ldscript.powerpc b/sys/conf/ldscript.powerpc index 2bfc02768a22..bb72d25e6af7 100644 --- a/sys/conf/ldscript.powerpc +++ b/sys/conf/ldscript.powerpc @@ -79,8 +79,20 @@ SECTIONS . = ALIGN(4096); .got : { *(.got) } .got.plt : { *(.got.plt) } - - + .init_array : + { + PROVIDE_HIDDEN (__init_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.init_array.*))) + KEEP (*(.init_array)) + PROVIDE_HIDDEN (__init_array_end = .); + } + .fini_array : + { + PROVIDE_HIDDEN (__fini_array_start = .); + KEEP (*(SORT_BY_INIT_PRIORITY(.fini_array.*))) + KEEP (*(.fini_array)) + PROVIDE_HIDDEN (__fini_array_end = .); + } .dynamic : { *(.dynamic) } :kernel :dynamic /* Put .ctors and .dtors next to the .got2 section, so that the pointers get relocated with -mrelocatable.
