2023-07-17 | Support NEXT_SECTION in ALIGNOF and SIZEOF | Alan Modra | 1 | -0/+1 | |
This patch is aimed at making __bss_start properly aligned with the first of any bss-style sections following. Most of the work here involves keeping track of the last output section seen when processing the linker script. You can almost align __bss_start properly by using ${RELOCATING+. = ALIGN(${DATA_SDATA-${NO_SMALL_DATA-ALIGNOF(.${SBSS_NAME}) != 0 ? ALIGNOF(.${SBSS_NAME}) : }}${BSS_PLT+ALIGNOF(.plt) != 0 ? ALIGNOF(.plt) : }ALIGNOF(.${BSS_NAME}));} and changing every place that defines NO_SMALL_DATA to use " ", but having two .plt sections (marked SPECIAL) on some backends foils that idea. The problem is that you only want to pick up the following .plt, not the one preceeding __bss_start in the data segment if the backend decides that is the proper .plt section. Perhaps that could be fixed too, but I decided instead to extend the linker script a little. THIS_SECTION and PREV_SECTION could easily be added too. * ld.texi (ALIGNOF, SIZEOF): Update and mention NEXT_SECTION. * ldexp.c (output_section_find): New function.

2023-03-16 | Re: Add --enable-linker-verssion | Alan Modra | 1 | -3/+2 | |
Output sections without any input sections to initialise their flags have their flags initialised by data statements to LOAD, ALLOC, HAS_CONTENTS by default. This is wrong for .comment. Fix that by making the script initialise the section type to INFO, one of the noalloc section types. That also allows the address of .comment to be set to zero, as is usual for non-alloc sections. Also, use source_sh for all of the sourced scripts to set up make dependencies.

2018-10-29 | ld -r script fixes | Alan Modra | 1 | -2/+2 | |
For ld -r, we generally set the VMA of sections to zero. This is done to make the output of ld -r most similar to that output by the assembler, which generally has sections starting at VMA zero. In some cases that covers for backend bugs which would mis-handle relocatable object files with non-zero section VMAs. This patch fixes a few sections that didn't have zero VMAs for ld -r. A missing zero on .note.gnu.build-id and .eh_frame_hdr doesn't matter much since these are linker generated symbols only output on final link, but it's good to be consistent. * Makefile.am (ei386beos.c, ei386go32.c): Correct dependencies. * Makefile.in: Regenerate. * scripttempl/elf.sc (.note.gnu.build-id, .eh_frame_hdr): Set address with ${RELOCATING-0}. * scripttempl/arclinux.sc: Likewise. * scripttempl/armbpabi.sc: Likewise. * scripttempl/avr.sc: Likewise. * scripttempl/elf64hppa.sc: Likewise. * scripttempl/elf_chaos.sc: Likewise. * scripttempl/elfarc.sc: Likewise. * scripttempl/elfxtensa.sc: Likewise. * scripttempl/mep.sc: Likewise. * scripttempl/nds32elf.sc: Likewise. * scripttempl/pru.sc: Likewise. * scripttempl/elf32msp430.sc: Likewise, and for other sections. * scripttempl/epiphany_4x4.sc: Similarly. | |||||

"ld -r" generally should not combine object file sections with different names. For example, "ld -r" should not combine ".text", ".text.hot" and ".text.cold" into an output ".text" section.
