[PATCH] ld: Estimate output section layout before sizing dynamic sections
H.J. Lu

Sat Feb 1 08:53:30 GMT 2025
When sizing dynamic sections, elf_x86_64_scan_relocs converts GOTPCREL
relocations to R_X86_64_PC32, R_X86_64_32S or R_X86_64_32 for local
symbols. But at that time, since the output section layout is unknown,
the local symbol values can't be determined. Later linker issues an
error if the converted relocation overflows when resolving relocations
against these local symbols. Update the linker so that an ELF target
can opt-in to estimate output section layout before sizing dynamic
sections. The linker created sections are excluded when estimating
output section layout as sizing dynamic sections may change linker
created sections. Update the x86-64 ELF linker to use the preliminary
section layout info to skip the GOTPCREL relocation conversion if the
converted relocation overflows.
