Add divdi3 build on sparc32 as before the patch. 2. Enforce -Wl,-noexecstack on ld.so build. I would prefer 2. since we already expect loader to have a non-executable stack and gentoo wiki [1] all current architectures with supported gcc/binutils version should support the linker option.

Enforce -Wl,-noexecstack on ld.so build. 3. Add .note.GNU-stack section in libgcc/config/sparc/lb1spc.S (possibly conditioned on defined(__ELF__) && defined(__linux__), as in other architecture-specific .S files). That seems to me to be the right approach, and would fix it for other software using these libgcc functions as well. And as a very small safe patch it should be suitable for backporting onto active GCC release branches. -- Joseph S. Myers joseph@codesourcery.com

As noted in [1], divdi3 object is only exported in a handful ABIs (i386, m68k, powerpc32, s390-32, and ia64), however it is built for all current architectures regardless. This patch refact the make rules for this object to so only the aforementioned architectures that actually require it builds it. Also, to avoid internal PLT calls to the exported symbol from the module, glibc uses an internal header (symbol-hacks.h) which is unrequired (and in fact breaks the build for architectures that intend to get symbol definitions from libgcc.a). The patch also changes it to create its own header (divdi3-symbol-hacks.h) and adjust the architectures that require it accordingly. I checked the build/check (with run-built-tests=no) on the following architectures (which I think must cover all supported ABI/builds) using GCC 6.3: aarch64-linux-gnu alpha-linux-gnu arm-linux-gnueabihf hppa-linux-gnu ia64-linux-gnu m68k-linux-gnu microblaze-linux-gnu mips64-n32-linux-gnu mips-linux-gnu mips64-linux-gnu nios2-linux-gnu powerpc-linux-gnu powerpc-linux-gnu-power4 powerpc64-linux-gnu powerpc64le-linux-gnu s390x-linux-gnu s390-linux-gnu sh4-linux-gnu sh4-linux-gnu-soft sparc64-linux-gnu sparcv9-linux-gnu tilegx-linux-gnu tilegx-linux-gnu-32 tilepro-linux-gnu x86_64-linux-gnu x86_64-linux-gnu-x32 i686-linux-gnu I only saw one regression on sparcv9-linux-gnu (extra PLT call to .udiv) which I address in next patch in the set. It also correctly build SH with GCC 7.0.1 (without any regression from c89721e25d).
