2016-09-18On arm, set the "triple" to armv7-unknown-openbsdX.Y-gnueabi. This makes theMark Kettenis

2016-09-07Backport https://reviews.llvm.org/rL279449 from upstreamStefan Kempf
ok pascal@ Original commit message: [SSP] Do not set __guard_local to hidden for OpenBSD SSP guard_local is defined as long on OpenBSD. If the source file contains a definition of guard_local, it mismatches with the int8 pointer type used in LLVM. In that case, Module::getOrInsertGlobal() returns a cast operation instead of a GlobalVariable. Trying to set the visibility on the cast operation leads to random segfaults (seen when compiling the OpenBSD kernel, which also runs with stack protection). In the kernel, the hidden attribute does not matter. For userspace code, guard_local is defined as hidden in the startup code. If a program re-defines guard_local, the definition from the startup code will either win or the linker complains about multiple definitions (depending on whether the re-defined __guard_local is placed in the common segment or not). It also matches what gcc on OpenBSD does.

2016-08-14Turning off relro shouldn't insert padding into the middle of the relroPhilip Guenther
section; remove the PAD_GOT0 use that I should have deleted before. This caused ld.so crashes on arm when building binutils. critical debugging observations by kettenis@
2016-08-10auto-dope-slap: mips64 has 16K pages, not 4K. With that fixed, enable RELROPhilip Guenther
Per feedback from kettenis@, Miod, and deraadt@, the padding between text and rodata will be retained for consistency with other archs, to minimize reliance on the R4000 EOP bug workaround, and to enable possible future work. ok deraadt@

2016-08-10Cover your kid's remaining eye and lock up the pets for the great old onesPhilip Guenther
have been disturbed: rework the linker script and then enable RELRO support on all but mips64 (something something padding) and m88k (untested). This extends the RO coverage from just .got and .cdtors to also include .openbsd.randomdata, .jcr, .dynamic, and .data.rel.ro., and moves more segments from the text section to the rodata section. Depends on the previous csu and ld.so work; reinstall those *before* rebuilding ld, or just get a snapshot. clues from kettenis assistance testing and ok deraadt@

2016-08-01Make sure variables are initialized before using themStefan Kempf
In elf.c, do not increment `s' before it is initialized. At the time of the increment, `s' is otherwise unused anyway. In elflink.c, initialize sec_contents and l_sec_contents to make sure that the free(sec_contents) and free(l_sec_contents) are called on valid pointers. ok jca@ guenther@
