Jan Beulich f2d4ba38f5 gas/ELF: don't accumulate .type settings ... Recently a patch was submitted for a Xen Project test harness binary to override the compiler specified @object to @func (see [1]). In a reply I suggested we shouldn't make ourselves dependent on currently unspecified behavior of gas here: It accumulates all requests, and then bfd/elf.c:swap_out_syms(), in an apparently ad hoc manner, prioritizes certain flags over others. Make the behavior predictable: Generally the last .type is what counts. Exceptions are directives which set multiple bits (TLS, IFUNC, and UNIQUE): Subsequent directives requesting just the more generic bit (i.e. FUNC following IFUNC) won't clear the more specific one. Warn about incompatible changes, except from/to STT_NOTYPE. Also add a new target hook, which hppa wants to use right away afaict. In the course of adding the warning I ran into two ld testsuite failures. I can only assume that it was a copy-and-paste mistake that lead to the same symbol having its type set twice.
