64-bit ARM instruction set: ARMv8, Aarch64 is ARM and Fedora name, for
what is known arm64 in the kernel and Debian/Ubuntu ports.

Title:
  valgrind does not work on amd64 (strlen missing)

Status in Valgrind:
  Unknown
Status in “glibc” package in Ubuntu:
  Confirmed
Status in “valgrind” package in Ubuntu:
  Confirmed

Bug description:
  It seems that strlen has been inlined in the amd64 version of glibc
  currently used in Ubuntu 13.10 (saucy). This makes it impossible to
  run valgrind. It fails with the following output:

  valgrind:  Fatal error at startup: a function redirection
  valgrind:  which is mandatory for this platform-tool combination
  valgrind:  cannot be set up.  Details of the redirection are:
  valgrind:  
  valgrind:  A must-be-redirected function
  valgrind:  whose name matches the pattern:      strlen
  valgrind:  in an object with soname matching:   ld-linux-x86-64.so.2
  valgrind:  was not found whilst processing
  valgrind:  symbols from the object with soname: ld-linux-x86-64.so.2
  valgrind:  
  valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
  valgrind:  package on this machine.  (2, longer term): ask the packagers
  valgrind:  for your Linux distribution to please in future ship a non-
  valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
  valgrind:  that exports the above-named function using the standard
  valgrind:  calling conventions for this platform.  The package you need
  valgrind:  to install for fix (1) is called
  valgrind:  
  valgrind:    On Debian, Ubuntu:                 libc6-dbg
  valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
  valgrind:  
  valgrind:  Cannot continue -- exiting now.  Sorry.

  Either the glibc package needs to be fixed so it does not inline
  strlen or valgrind needs to be fixed. A work-around patch to valgrind
  can be found in this thread:
