Comment 28 for bug 1247026

Hi All,

I am facing with valgrind as below. Please let me know the solution for it.

rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ uname -r
4.10.0-42-generic
rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial
rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$

rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ sudo make clean
rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ sudo ./configure --host=powerpc-pc-linux LDFLAGS=-static CC=/opt/ELDK42/usr/bin/ppc_85xx-gcc CXX=/opt/ELDK42/usr/bin/ppc_85xx-g++ --enable-tls --prefix=/home/rajeshsingh/valgrind_bins/ --exec-prefix=/home/rajeshsingh/valgrind_bins
rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ sudo make
rajeshsingh@rajesh-dt:~/Downloads/valgrind-3.13.0$ sudo make install

After that I am makeing this as tar.gz file and copying on device and uncomprees it.

On Device:

tar -xjvf valgrind.tar.gz

mv valgrind_bins/bin/valgrind /etc/bin/
cp valgrind_bins/lib/valgrind/default.supp /etc/lib/valgrind/
VALGRIND_LIB=/tmp/valgrind_bins/lib/valgrind/
export VALGRIND_LIB
/etc/bin/valgrind ls

valgrind: Possible fixes: (1, short term): install glibc's debuginfo

valgrind: for your Linux distribution to please in future ship a non-

valgrind: Cannot continue -- exiting now. Sorry.

bash-4.3#

I added some check in m_redir.c file and compile and loaded valgrind.

+#if CI_HACK_strlen
      add_hardwired_spec(
         "ld.so.1", "strlen",
         (Addr)&VG_(ppc32_linux_REDIR_FOR_strlen),
         complain_about_stripped_glibc_ldso
      );
+#endif

disInstr(ppc): found an AltiVec or an e500 instruction 0x13C17320
that can't be handled by Valgrind. If this instruction is an
Altivec instruction, Valgrind must be run on a host that supportsAltiVec instructions. If the application was compiled for e500, then
unfortunately Valgrind does not yet support e500 instructions.
==1836== valgrind: Unrecognised instruction at address 0x400df78.
==1836== at 0x400DF78: ??? (in /lib/ld-2.6.so)
==1836== Your program just tried to execute an instruction that Valgrind
==1836== did not recognise. There are two possible reasons for this.
==1836== 1. Your program has a bug and erroneously jumped to a non-code
==1836== location. If you are running Memcheck and you just saw a
==1836== warning about a bad jump, it's probably your program's fault.
==1836== 2. The instruction is legitimate but Valgrind doesn't handle it,
==1836== i.e. it's Valgrind's fault. If you think this is the case or
==1836== you are not sure, please let us know and we'll try to fix it.
==1836== Either way, Valgrind will now raise a SIGILL signal which will
==1836== probably kill your program.

Please let me know how to comeout from this issue ?
