-Subject: [PATCH] Fix combreloc test with BSD grep
-
-The test for "-z combreloc" fails when cross-compiling on a machine
-that uses BSD grep (e.g. on macos). grep complains about empty
-subexpression and exits with non-zero status, which is interpreted
-by configure as "not found". As a result, support for "-z combreloc"
-(HAVE_Z_COMBRELOC) is not detected, leading to link failure on SPARC.
-
- * configure.ac: Avoid empty subexpression in grep.

-commit db3d848e154b00071f4a5e729d5884efad410109
-Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
-Date: Wed Mar 15 15:44:59 2017 -0300
-
- Build divdi3 only for architecture that required it
-
- 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).

- sparc: Fix .udiv plt on libc
-
- With the removal of divdi3 object from sparcv9-linux-gnu build, its
- definition came from libgcc and its functions internall calls .udiv.
- Since glibc also exports these symbols for compatibility reasons, it
- will end up creating PLT calls internally in libc.so.
-
- To avoid it, this patch uses the linker option --wrap to replace all
- the internal libc.so .udiv calls to the wrapper __wrap_.udiv. Along
- with strong alias in the udiv implementations, it makes linker do
- local calls.
-
- Checked on sparcv9-linux-gnu.
-
- * sysdeps/sparc/sparc32/Makefile (libc.so-gnulib): New rule.
- * sysdeps/sparc/sparc32/sparcv8/udiv.S (.udiv): Make a strong_alias
- to __wrap_.udiv.
- * sysdeps/sparc/sparc32/sparcv9/udiv.S (.udiv): Likewise.
- * sysdeps/sparc/sparc32/udiv.S (.udiv): Likewise.
