[Bug ld/23169] IFUNC pointer should be allowed in executable
https://sourceware.org/bugzilla/show_bug.cgi?id=23169 --- Comment #9 from H.J. Lu --- (In reply to Fangrui Song from comment #8) > Can https://sourceware.org/glibc/wiki/GNU_IFUNC to updated to document what > is supported and what isn't supported? > IFUNC documentation needs improvements. > > Is the idea that > (1) the main executable is relocated the last. > (2) by making the main executable STT_GNU_IFUNC STT_FUNC, ifunc resolver > will not be called while the main executable is unresolved Correct. > (3) How does an ifunc resolver defined in another DSO work? Let the user > ensures DT_NEEDED BFS order or the ld.so itself does topological sorting?

[Bug gas/27193] Linkonce section with unused section symbols won't match comdat section without unused section symbols
https://sourceware.org/bugzilla/show_bug.cgi?id=27193 --- Comment #10 from cvs-commit at gcc dot gnu.org --- The master branch has been updated by H.J.

Lu Date: Sun Jan 17 20:01:16 2021 -0800 ld/elf: Ignore section symbols when matching linkonce with comdat When deciding if a single member comdat group section in file FOO should be discarded by a linkonce section in file BAR, we check if 2 sections define the same set of local and global symbols. When only one of the files doesn't contain the unused section symbols in the symbol table, such as object files generated by clang or GNU assembler with commit d1bcae833b32f1408485ce69f844dcd7ded093a8 Author: H.J. Lu Date: Thu Jan 7 06:42:00 2021 -0800 ELF: Don't generate unused section symbols the check will fail since one file has the extra unused section symbols.
