be placed towards the front of local GOT space, while entries addressed via a 32-bit index are placed towards the rear.

2014-04-15[AArch64] Fix off by one error in instruction relaxation mask.Marcus Shawcroft2-1/+5
The AArch64 TLSDESC to IE relaxation code uses a bit mask intended to ensure that destination register in a relaxed ldr instruction is always X0. The mask has an off by one error resulting in the most significant bit of the destination register being retained in the relaxed instruction. The issue generally appears when the compiler emits TLS accesses code under high register pressure resulting in a broken code sequence.

2014-04-11PE32+ binaries that use addresses > 1^32 have a problem in that the linkerNick Clifton2-0/+39
converts some address expressions into absolute values, but the PE format only stores absolutes as 32-bits. This is a partial solution which attempts to convert such absolute values back to section relative ones instead. It fails for symbols like __image_base and ImageBase__, but it is unclear as to whether these values are ever actually used by applications. PR ld/16821 * peXXigen.c (abs_finder): New function. (_bfd_XXi_swap_sym_out): For absolute symbols with values larger than 1^32 try to convert them into section relative values instead.

2014-04-09ppc476 icache workaround fix for bctrAlan Modra2-19/+54
I got the ppc476 workaround wrong. bctr (and bctrl) as the last instruction in a page can hit the icache bug if the preceding mtctr insn is close by, and the destination is in the first few instructions on the next page. This scenario can occur with code generated by gcc to implement switch statements, or in code generated to call by function pointer. To prevent the bctr problem it is also necessary to remove other instructions that otherwise would be safe. bfd/ * elf32-ppc.c (ppc_elf_relocate_section): Remove bctr from list of safe ppc476 insns at end of page. Also remove non-branch insns. Expand comments. ld/ * emultempl/ppc32elf.em (no_zero_padding, ppc_finish): New functions. (LDEMUL_FINISH): Define.

2014-04-02Handle VDSO section headers past end of pageAlan Modra6-91/+145
When a VDSO gets large enough that it doesn't entirely fit in one page, but not so large that the part described by the program header exceeds one page, then gdb/BFD doesn't read the section headers and symbol table information.
