[Valgrind-users] Valgrind on mips64

[Vikram C. <vik...@gm...>]

Hi All,

I am trying to run valgrind on our mips 64 bit platform. I have compiled
valgrind 3.13 with following configure arguments:

./configure --host=mips64-poky-linux --prefix=...  --build=x86_64-linux
CC=... CXX=...

My code access memory-address range starting from 0x8001180000000000. This
is ligitimate access.
We have added following valgrind macro in the code before this access as:
VALGRIND_MALLOCLIKE_BLOCK(CVMX_ADD_IO_SEG(0x8001180000000000ull),
0x0000000000f00000ull, 0, 1);

But when the code tries accessing the memory region, it simply terminates
with SIGBUS:

==1492== Process terminating with default action of signal 10 (SIGBUS)


If we remove the above valgrind macro, the program still terminates with
SIGBUS with additional error message.

==890==  Address 0x8001180000001500 is not stack'd, malloc'd or (recently)
free'

==890== Process terminating with default action of signal 10 (SIGBUS)


I have tried valgrind 3.12 with same issue. If I run any other application
under valgrind that does not access this memory region, it works fine.

Also, this application runs fine without valgrind.

Please let me know what can we do to get around this issue.

Thanks
