Package: src:binutils The upstream binutils commit below reduced the section alignment of armhf executables (including shared libraries) from 64k to 4k, on the basis that the additional bloat is not justified, given that arm64 hosts running 64k pagesize kernels with armhf user space are not used in practice.
However, the situation is slightly different today on Debian, where a 16k pagesize kernel is provided that enables compat support, and is therefore able to execute armhf user space. The only impediment is the fact that armhf binaries are no longer compatible with this, due to the change below. To accommodate this use case, revert the patch. This makes the generated executables compatible with compat mode on arm64 systems running 16k kernels. | commit 1a26a53a0dee39106ba58fcb15496c5f13074652 | Author: Hans-Peter Nilsson <h...@axis.com> | Date: Tue Jan 3 03:19:54 2023 +0100 | | ARM: Fix ld bloat introduced between binutils-2.38 and 2.39 More info at https://sourceware.org/bugzilla/show_bug.cgi?id=30033 --- debian/patches/armhf-64k-alignment.diff | 15 +++++++++++++++ debian/patches/series | 3 +++ 2 files changed, 18 insertions(+) diff --git a/debian/patches/armhf-64k-alignment.diff b/debian/patches/armhf-64k-alignment.diff new file mode 100644 index 0000000..7138330 --- /dev/null +++ b/debian/patches/armhf-64k-alignment.diff @@ -0,0 +1,15 @@ +--- a/bfd/elf32-arm.c ++++ b/bfd/elf32-arm.c +@@ -20355,7 +20355,11 @@ elf32_arm_backend_symbol_processing (bfd *abfd, asymbol *sym) + #define ELF_ARCH bfd_arch_arm + #define ELF_TARGET_ID ARM_ELF_DATA + #define ELF_MACHINE_CODE EM_ARM ++#ifdef __QNXTARGET__ + #define ELF_MAXPAGESIZE 0x1000 ++#else ++#define ELF_MAXPAGESIZE 0x10000 ++#endif + #define ELF_COMMONPAGESIZE 0x1000 + + #define bfd_elf32_mkobject elf32_arm_mkobject + diff --git a/debian/patches/series b/debian/patches/series index cf4b64e..7a68bd4 100644 --- a/debian/patches/series +++ b/debian/patches/series @@ -34,3 +34,6 @@ mips-hack.diff perl-shebang.diff env-package-metadata.diff pr32392-workaround.diff + +# https://sourceware.org/bugzilla/show_bug.cgi?id=30033 +armhf-64k-alignment.diff
