I noticed in gdb/tui/tui-stack.c a source-level micro-optimization where
strlen with a string literal argument:
...
strlen ("bla")
...
is replaced with sizeof:
...
sizeof ("bla") - 1
...
The benefit of this is that the optimization is also done at O0, but the
drawback is that it makes the expression harder to read.
Use const std::string to encapsulate the string literals, and use
std::string::size () instead.
I tried making the string names (PROC_PREFIX, LINE_PREFIX, PC_PREFIX and
SINGLE_KEY) lower-case, but that clashed with a pre-existing pc_prefix, so
I've left them upper-case.
Tested on x86_64-linux.
