Hello, All
When (gdb) ptype global_options
I will get definition of the type of global_options whose type is
'struct gcc_options'
Is it possible get the definition location(which file it is defined
in) info of 'struct gcc_options'?
I know the line info of 'struct gcc_options' in ELF may lose, but is
gdb has the facility show the line info of the symbol?
thx
