# FEATURES
# 
# The following macro definitions adjusts various options on build parameters
# that affect the build output. You can specify them as part of the configure
# options (--enable-FEATURE or --disable-FEATURE) or on the command line. Each
# of them requires either a 0 or 1 value.

# When WANT_ASSERTIONS is enabled, builds of all of the LLVM code will 
# exclude assertion checks, otherwise they are included.
WANT_ASSERTIONS := @WANT_ASSERTIONS@

# When WANT_CHECkING is enabled, this turns on expensive runtime checking such as
# GXXLIB_DEBUG, malloc debug, etc.
WANT_CHECKING := @WANT_CHECKING@

# When WANT_DEBUG is enabled, the compiler generates debug symbols in object code
# and optional code is enabled.
WANT_DEBUG := @WANT_DEBUG@

# When ENABLE_DOXYGEN is enabled, the doxygen documentation will be built
WANT_DOXYGEN = @WANT_DOXYGEN@

# When WANT_OPTIMIZED is enabled, LLVM code is optimized and output is put
# into the "Release" directories. Otherwise, LLVM code is not optimized and 
# output is put in the "Debug" directories.
WANT_OPTIMIZED := @WANT_OPTIMIZED@

# When WANT_OPT_FOR_SIZE is enabled, the optimizations performed will favor
# optimizing for code and data size rather than for speed.
WANT_OPT_FOR_SIZE := @WANT_OPT_FOR_SIZE@

# When ENABLE_PROFILING is enabled, the llvm source base is built with profile
# information to allow gprof to be used to get execution frequencies.
WANT_PROFILING = @WANT_PROFILING@

# When WANT_STRIPPED is enabled, executables and libraries will be
# stripped of debug symbols

# When WANT_THREADS is enabled, thread libraries will be found and included
WANT_THREADS := @WANT_THREADS@

# This option tells the Makefiles to produce verbose output.
# It essentially prints the commands that make is executing
