[Bug gas/3041] Bogus jump to weak symbol on m68k-unknown-netbsd
--- Additional Comments From vincent dot riviere at freesbee dot fr 2007-04-28 21:38 --- Created an attachment (id=1739) --> (http://sourceware.org/bugzilla/attachment.cgi?id=1739&action=view) Write correct values and relocs into a.out object files After spending *weeks* in the debugger, I finally managed to get it work. My patch is attached to this message. It is is composed of 4 parts : 1) The patch provided by Nick in Comment #5. It is necessary to generate a reloc with the correct symbol name. 2) Never relax references to weak symbols, as they must be full absolute pointers in order to be relocated. 3) In md_apply_fix(): Always put zero values into frags referencing a weak symbol. 4) In tc_gen_reloc(): Adjust addend in order to force bfd_install_relocation() to put a zero value into the frags referencing a weak symbol. This patch affects only a.out and m68k, and only when weak symbols are used. It may not affect anything else. I think it works as expected. Could someone verify it is OK and check this in, please ?
