On ELF, (NOLOAD) sets the section type to SHT_NOBITS[1]. It is conceptually inappropriate for .plt and .text.* sections which are always SHT_PROGBITS. In GNU ld, if PLT entries are needed, .plt will be SHT_PROGBITS anyway and (NOLOAD) will be essentially ignored. In ld.lld, since https://reviews.llvm.org/D118840 ("[ELF] Support (TYPE=<value>) to customize the output section type"), ld.lld will report a `section type mismatch` error. Just remove (NOLOAD) to fix the error. [1] https://lld.llvm.org/ELF/linker_script.html As of today, "The section should be marked as not loadable" on https://sourceware.org/binutils/docs/ld/Output-Section-Type.html is outdated for ELF.
