Clang emits the '%u' form, while SORT is an alias for SORT_BY_NAME, hence will result in wrong order of constructors / destructors in output sections. Fix by using the correct sorting command SORT_BY_INIT_PRIORITY instead [1]. The functions referenced by section .fini_array is in the normal order, but been executed in the reverse order. The order is same with .init_array section. Currently these sections are not used, there should be no functional change. Note: As for the .ctors and .dtors sections, both Clang and GCC emit the priority suffix in the form of '%05u', so there is no semantic difference between SORT_BY_NAME and SORT_BY_INIT_PRIORITY for those sections [2]. This fix is extracted from a bigger patch [3] of hselasky, with additional fix for .fini_array section. 1. https://sourceware.org/binutils/docs/ld/Input-Section-Wildcards.html 2. https://reviews.llvm.org/D91187 3. https://reviews.freebsd.org/D40467 Reviewed by: imp (previous version) Obtained from: hselasky MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D45194 (cherry picked from commit e15b5ba77d693609c9a452d1b0a1cdd5eb29350d) (cherry picked from commit 1d94490aee5c8353ed08909bbd00af7cfb48a8dc) --- sys/conf/ldscript.amd64 | 4 ++-- sys/conf/ldscript.i386 | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/sys/conf/ldscript.amd64 b/sys/conf/ldscript.amd64 index 9c6e603a5753..72dc573f113e 100644 --- a/sys/conf/ldscript.amd64 +++ b/sys/conf/ldscript.amd64 @@ -93,15 +93,15 @@ SECTIONS .init_array : { PROVIDE_HIDDEN (__init_array_start = .); - KEEP (*(SORT(.init_array.*))) + 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)) - KEEP (*(SORT(.fini_array.*))) PROVIDE_HIDDEN (__fini_array_end = .); } _start_ctors = .; diff --git a/sys/conf/ldscript.i386 b/sys/conf/ldscript.i386 index 6563ed2cd623..c46a9910eb3b 100644 --- a/sys/conf/ldscript.i386 +++ b/sys/conf/ldscript.i386 @@ -87,15 +87,15 @@ SECTIONS .init_array : { PROVIDE_HIDDEN (__init_array_start = .); - KEEP (*(SORT(.init_array.*))) + 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)) - KEEP (*(SORT(.fini_array.*))) PROVIDE_HIDDEN (__fini_array_end = .); } _start_ctors = .;
