@kindex set print entry-values
|

Set printing of frame argument values at function entry. In some cases
|

@value{GDBN} can determine the value of function argument which was passed by
|

the function caller, even if the value was modified inside the called function

and therefore is different. With optimized code, the current value could be
|
||||
unavailable, but the entry value may still be known.
|
||||
|
||||
The default value is @code{default} (see below for its description). Older
|
||||
@value{GDBN} behaved as with the setting @code{no}. Compilers not supporting
|
||||
this feature will behave in the @code{default} setting the same way as with the
|

@code{no} setting.

This functionality is currently supported only by DWARF 2 debugging format and

the compiler has to produce @samp{DW_TAG_GNU_call_site} tags. With

@value{NGCC}, you need to specify @option{-O -g} during compilation, to get
