Binary Dump via GDB

Recently at work, I’ve been relying on a very handy tool on GDB called dump memory to dump the contents of any contiguous range of memory. I first came aware of this tool from a stackoverflow answer that a coworker linked as each of us had a need to dump the contents of memory copied from the GPU to the host memory for our respective tickets.

Syntax: dump memory <filename> <starting address> <ending address>

For instance,

dump memory vectorData.bin 0x7ffff2d96010  0x7ffff53bba10

or suppose you have a vector vec, you could dump the contents of the vector via:

dump memory vectorData.bin vec.data() vec.data()+vec.size()
