llvm dev - Jan 2011 - [LLVMdev] about NDEBUG

Hi Mr/Mz,

I have built and installed llvm-2.8 in debug mode using:
>SRC_DIR/configure --prefix=INS_DIR --enable-debug-runtime
 --disable-optimized --enable-debug-symbols
>make install

It seems the NDEBUG controls a lot of print-out of debug information, by
using DEBUG() or dbgs().

And it is said that NDEBUG is in enabled in debug mode, but I find it does
not work and the -debug option is not recognized. How should I enable NDEBUG
or enable DEBUG() and dbgs()? Should I define NDEBUG in the .cpp files
related, when I need the debug information?

actually it is the opposite: NDEBUG is enabled when not in debug mode.  The
"N" in
NDEBUG stands for "Not".
