2017-06-16Rewrite __start and __stop symbol handlingAlan Modra36-7/+180
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

2017-06-13Always define referenced __start_SECNAME/__stop_SECNAMEH.J. Lu5-103/+92
Currently, linker will define __start_SECNAME and __stop_SECNAME symbols only for orphaned sections. However, during garbage collection, ELF linker marks all sections with references to __start_SECNAME and __stop_SECNAME symbols as used even when section SECNAME isn't an orphaned section and linker won't define __start_SECNAME nor __stop_SECNAME. And ELF linker stores the first input section whose name matches __start_SECNAME or __stop_SECNAME in u.undef.section for garbage collection. If these symbols are provided in linker script, u.undef.section is set to the section where they will defined by linker script, which leads to the incorrect output. This patch changes linker to always define referenced __start_SECNAME and __stop_SECNAME if the input section name is the same as the output section name, which is always true for orphaned sections, and SECNAME is a C identifier. Also __start_SECNAME and __stop_SECNAME symbols are marked as hidden by ELF linker so that __start_SECNAME and __stop_SECNAME symbols for section SECNAME in different modules are unique. For garbage collection, ELF linker stores the first matched input section in the unused vtable field. bfd/ PR ld/20022 PR ld/21557 PR ld/21562 PR ld/21571 * elf-bfd.h (elf_link_hash_entry): Add start_stop.

2017-06-08[ARC] Fixed condition to generate TEXTREL.Cupertino Miranda2-1/+7
TEXTREL was being generated even when relocatable .o files had the .rela.text section. Now it is limitted only to dynamic object files that still have them. Nevertheless, our target aborts in those cases due to architecture limitations where icache is not coherent with dcache, and to force this coherence expensive kernel level support would be needed. bfd/ChangeLog: Cupertino Miranda <cmiranda@synopsys.com> * elf32-arc.c (elf_arc_size_dynamic_sections): Changed condition to require TEXTREL.
