ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page.

ppc476 icache bug workaround This implements a work-around for an icache bug on 476 that can cause execution of stale instructions when control falls through from one page to the next. The idea is to prevent such fall-through by replacing the last instruction on a page with a branch to a patch area containing the instruction, then branch to the next page. The patch also fixes a number of bugs in the existing support for long branch trampolines. bfd/ * elf32-ppc.c (struct ppc_elf_link_hash_table): Add params. Delete emit_stub_syms, no_tls_get_addr_opt.

Rewrite ppc32 backend .sdata and .sdata2 handling 1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections.
