[Valgrind-developers] x86_64: using V in a mixed executable env

[Rich C. <Ric...@me...>]

I'm testing on the x86_64 (amd64) platform and was wondering what the
expected behaviour of V should be in a mixed executabled environment.

I can have both 32-bit and 64-bit applications that I would want to run
V against.  When I run V and it doesn't match the executable type it was
built for, like running the ELF-64 binary against an ELF-32 program, 
V complains
    valgrind: wrong ELF executable class (eg. 32-bit instead of 64-bit)
    valgrind: do_exec(....) failed: Exec format error

Should V detect the ELF class at startup and use V code from 
/usr/local/lib/valgrind or /usr/local/lib64/valgrind based on the ELF class ?
