non-PIC references to __ehdr_start in pie and shared Rather than hacking every backend to not discard dynamic relocations against an undefined hidden __ehdr_start, make it appear to be defined early. We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Define __ehdr_start before size_dynamic_sections and restore afterwards. ld/testsuite/ * ld-elf/ehdr_start-shared.d: New. * ld-elf/ehdr_start-userdef.d: xfail frv. * ld-elf/ehdr_start-weak.d: Likewise. * ld-elf/ehdr_start.d: Likewise. 2014-01-15 19:20:55 +08:00			`#xfail: frv--`
