Similar to other architectures with IFUNC binutils/glibc support, this patch enables the ifunc attribute for ARM GNU/Linux. Although not required for build master GLIBC, the intention is to allow refactor its assembly implementation to C. Tested compilation of glibc (in conjunction with a glibc patch to support using the attribute on ARM) with build-many-glibcs.py (with a patch to add a armv7 variant which enables multiarch). I have not run the GCC tests for ARM. * config.gcc (default_gnu_indirect_function): Default to yes for arm*-*-linux* with glibc. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@253635 138bc75d-0d04-0410-961f-82ee72b054a4

…ic FPU selection Libatomic builds a few functions for Arm with an explicit -march option. This option does not specify an FPU, which can lead to problems when targeting a hard-float or softfp environment since the architecture appears to be incompatible with the selected ABI. The fix is simple enough, just add +fp (the minimum floating point option) to the architecture. We don't use anything from the FP architecture, so it shouldn't really change anything; and if we are building for -mfloat-abi=soft the canonicalization process will remove the unnecessary fp attributes anyway. * Makefile.am: (IFUNC_OPTIONS): Set the architecture to -march=armv7-a+fp on Linux/Arm. * Makefile.in: Regenerated. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@253935 138bc75d-0d04-0410-961f-82ee72b054a4
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf A proposal is to introduce a target independent flag -fcf-protection=[none|branch|return|full] with a semantic to instrument a code to control validness or integrity of control-flow transfers using jump and call instructions. The main goal is to detect and block a possible malware execution through transfer the execution to unknown target address. Implementation could be either software or target based. Any target platforms can provide their implementation for instrumentation under this option. The compiler should instrument any control-flow transfer points in a program (ex. call/jmp/ret) as well as any landing pads, which are targets of control-flow transfers. A new 'nocf_check' attribute is introduced to provide hand tuning support. The attribute directs the compiler to skip a call to a function and a function's landing pad from instrumentation. The attribute can be used for function and pointer to function types, otherwise it will be ignored. Currently all platforms except i386 will report the error and do no instrumentation. i386 will provide the implementation based on a specification published by Intel for a new technology called Control-flow Enforcement Technology (CET). gcc/c-family/ * c-attribs.c (handle_nocf_check_attribute): New function.

Also fix 64-bit DWARF to read a 64-bit abbrev offset in the
compilation unit.
This is a backport of https://golang.org/cl/71171, which will be in
the Go 1.10 release, to the gofrontend copy. Doing it now because AIX
is pretty much the only system that uses 64-bit DWARF.
