Debugging with GDB

(1)

`b' cannot be used because these format letters are also used with the x command, where `b' stands for "byte"; see section Examining memory.

(2)

This is a way of removing one word from the stack, on machines where stacks grow downward in memory (most machines, nowadays). This assumes that the innermost stack frame is selected; setting $sp is not allowed when other stack frames are selected. To pop entire frames off the stack, regardless of machine architecture, use return; see section Returning from a function.

If you choose a port number that conflicts with another service, gdbserver prints an error message and exits.

(4)

In `gdb-4.15.1/gdb/refcard.ps' of the version 4.15.1 release.

If you have a more recent version of GDB than 4.15.1, look at the `README' file in the sources; we may have improved the installation procedures since publishing this manual.
