no, you are right, it's the same symbol information as with full debug
information (on all platforms). The difference between the two is only
optimization:
O | S | D | T
--------------------------------------
production-code| x | - | - | -
--------------------------------------
enable-symbols | x | x | - | -
--------------------------------------
enable-debug | - | x | - | -
--------------------------------------
enable-dbgutil | - | x | x | x
where
O: optimization
S: symbols
D: debug STL
T: trace facility
So to reflect what these options mean exactly one should name it as follows:
enable-symbols: --enable-symbols-and-preserve-optimization
enable-debug: --enable-symbols-and-disable-optimization
enable-dbgutil:
--enable-symbols-and-disable-optimization-and-enable-debugstl-and-enable-trace-facility
Given that we don't want to rename two last options, we are trying to
find a new (less confusing and not so long) name
for the first one:
--enable-symbols-and-preserve-optimization
Ideas?
Thanks
David
