To avoid the problem with register variables, you can do one of two
things. The first is to turn off the Automatic Register Variables option
while debugging your application. Turn it back on again when you are
done debugging and before your product ships.
The other thing you can do is to declare a local variable with the
volatile keyword:
volatile int x;
This will prevent the compiler from optimizing the variable, thereby
making it available for inspection.
If you turn off the Automatic Register Variables option, you can still force the compiler to
treat a particular variable as a register variable by declaring it with the register keyword.
Here’s an example:
register int x = 20;
Disable Inline Expansions
The Disable Inline Expansions option controls how inline functions are handled by the
compiler. By default, inline functions are expanded inline (placed in the code where
necessary) as you would expect. If you turn on this option, thereby disabling inline expansion,
inline functions will be treated as regular functions rather than as inline functions. Use of this
option is rare, but you may need to use it on occasion when debugging certain inline
functions.
If you change any of the options on the C++ page, you should do a
Build All immediately following. This will ensure that all modules are
built using the same compiler settings.
Pre-compiled Headers
Note the Pre-compiled Headers section on the C++ page of the Project Options dialog box.
A pre-compiled header is essentially an image of the symbol table for a project stored on disk.
The first time you build your program, C++Builder creates the pre-compiled header. On
subsequent makes, C++Builder can load the pre-compiled header from disk, which is much
faster than compiling the headers for each build. In addition, you can opt to cache the precompiled
header in memory. This increases compile speed even more because the precompiled
header can be held in memory rather than being loaded from disk when needed.
