I want to know how an expression is parsed and evaluated in Expression view
1. Does it uses Elf and dwarf parser ?
2. How is expression parsed as per c++ ?

The expression is send directly to gdb via MI and evaluated by gdb.

Hi Axel,
Thanks for the help!

I traversed the flow from Expression to gdb via MI Services.
I would like to know, how the C++ parser(in gdb) parses a expression? and
Does it consider the Elf parser/reader and dwarf parser/reader while evaluating the value of expression?

You should have a look at the gdb source code then and ask the gdb folks about this.
