2017-01-10[ARC] Add new linker emulation for npsGraham Markall8-2/+205
The arc700 nps variant uses some specific named sections to facilitate its CMEM based instructions, which operate on memory regions fixed at specific addresses. This commit adds the arclinux_nps emulation, which is based on the arclinux emulation. The new emulation uses the OTHER_SECTIONS variable in the emulation parameters script to provide symbols mapping to various locations in the CMEM space on nps. The accompanying test ensures that all symbols are provided at the correct address in the linker script. ld/ChangeLog: * Makefile.am: Add earclinux_nps.c target and add to ALL_EMULATION_SOURCES. * Makefile.in: Likewise, regenerated. * configure.tgt: Add arclinux_nps as an extra emulation for arc*-*-elf* and arc*-*-linux*. * emulparams/arc-nps.sh: New file. * emulparams/arclinux_nps.sh: New file. * testsuite/ld-arc/arclinux-nps.d, * testsuite/ld-arc/arclinux-nps.s: New test.
2017-01-09Remove some custom sections from RISC-V's default linker scriptsPalmer Dabbelt1-12/+0
This was added so compressed loads could have smaller offsets for accessing the data section, but the result was that writable sections ended up in INITIAL_READONLY_SECTIONS. This is a bad idea. The fix is to just remove this micro-optimization.

2017-01-02Run more ld tests when not nativeAlan Modra74-954/+596
Many of the ld tests are not run for cross builds, in some cases because the test needs to run a newly linked executable, and in others simply because it was easier to write the test for native only. Even when a test needs to run, it's good to compile and link to exercise the linker. So that's what this patch does. I've also rid us of the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's much simpler to just link with $CC. This does mean that a cross build with cross-compiler installed but no cross C-library will give lots of failures. If that turns out to be too annoying, I guess we can write a tcl procedure to detect it and not run all the extra tests. * Makefile.am (bootstrap): Delete rule.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra9-32/+88
Variables defined in shared libraries are copied into an executable's .bss section when code in the executable is non-PIC and thus would require dynamic text relocations to access the variable directly in the shared library. Recent x86 toolchains also copy variables into the executable to gain a small speed improvement. The problem is that if the variable was originally read-only, the copy in .bss is writable, potentially opening a security hole. This patch cures that problem by putting the copy in a section that becomes read-only after ld.so relocation, provided -z relro is in force. The patch also fixes a microblaze linker segfault on attempting to use dynamic bss variables. bfd/ PR ld/20995 * elf-bfd.h (struct elf_link_hash_table): Add sdynrelro and sreldynrelro.

2016-12-14ld: aarch64: fix TLS relaxation where TCB_SIZE is usedYury Norov4-0/+36
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for ilp32. During relaxation, ld goes to do a replace: bl __tls_get_addr => add R0, R0, TCB_SIZE But actual implementation is: bfd_putl32 (0x91004000, contents + rel->r_offset + 4); Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32. The possible fix for it is: bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4); But ilp32 also needs w-registers, so it's simpler to put proper instruction in #if/#else condition. There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new tests added for ilp32 mode to test it.

2016-12-03PowerPC64 dot-symbol compatibility bugfixesAlan Modra9-1/+95
Lots of fixes for the compatibility code that handles linking of -mcall-aixdesc code (or that generated by 12 year old gcc) with current ELFv1 ABI code. 1) A reference to a dot-symbol in an object file wasn't satisfied by a function descriptor in later object files. 2) The as-needed code had bit-rotted; Shared libs now need a strong reference to be counted as needed. 3) --gc-sections involving dot-symbols was broken, needing func_desc_adjust to be run early and lots of other fixes. bfd/ * elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined".
