2019-03-01Binutils: Always skip only 1 byte for CIE version 1's return address register.Tamar Christina2-4/+12
According to the specification for the CIE entries, when the CIE version is 1 then the return address register field is always 1 byte. Readelf does this correctly in read_cie in dwarf.c but ld does this incorrectly and always tries to read a skip_leb128. If the value here has the top bit set then ld will incorrectly read at least another byte, causing either an assert failure or an incorrect address to be used in eh_frame. I'm not sure how to generate a generic test for this as I'd need to write assembly, and it's a bit hard to trigger. Essentially the relocated value needs to start with something that & 0x70 != 0x10 while trying to write a personality. bfd/ChangeLog: * elf-eh-frame.c (_bfd_elf_write_section_eh_frame): Correct CIE parse.

Recent gcc commit b4371b277f1e ("[ARC] Enable init_array support") inhibits DT_"INIT,FINI} in favor of DT_{INIT,FINI}ARRAY. Even prior to that, it seems ARC port is the only one with this special DT_INIT/FINI handling in linker emulation. Removing it doesn't seem to change any uClibc/glibc testsuite results, so this can RIP anyways. bfd/ 2019-02-01 Vineet Gupta <vgupta@synopsys.com> * elf32-arc.c: Delete init_str, fini_str ld/ 2019-02-01 Vineet Gupta <vgupta@synopsys.com> * emultempl/arclinux.em : Delete special INIT/FINI handling.
