Re: [Valgrind-users] Request for ideas for Valgrind improvements (general or ARM)

[Vasily G. <vas...@gm...>]

OK, thanks!

And a couple of words about cross-platform checking. If I did understand
you correct you propose smth like running valgrind under quemu (1) or whole
quemu under valgrind (2).

(2) - will be significantly slower because we need to instrument whole
system (not one binary\application)
(1) - as far as I know only code generation (from arm to x86 binary) made
by quemu-user decreases work of application x4. And we will need to use
system-wide quemu (not only user) that also decreases speed. So, now ARM
has more than 1GHz and we will not improve situation with 4Ghz host.

I think that we can use assessment of quemu even if we plan write our own
VM in Valgrind. Maybe I am wrong.
