You can use valgrind on embedded systems as long as they run a
GNU/Linux OS.
I've used valgrind successfully many times on ARM architecture.
But I don't know if it works with Android, and I doubt it
works on baremetal
indeed.
I seem to recall Valgrind wasn't on OSX, either, at one point.
Maybe that has since been corrected.
Also, unless you're testing possible bugs in compiler backends or
the C standard library, it mostly doesn't matter. Compile on
regular x86/Linux and run valgrind/asan there.
Have I run into weird bugs that only occurred on one platform?
Yes. Were they _really_ rare? You betcha. *

failed for values over the integer maximum for 32-bits... (turns
out that platform had no FPU and it was a bug in its libc)
