2.3.4. Option Groups

Supported compilers come with predefined option groups. To see the actual compiler options they include, do:

make OPTS=full_debug info
make OPTS=debug info
make OPTS= info
make OPTS=optimized info

The bundled options are chosen so that

• full_debug: generates very slow code that traps many problems
• debug: generates faster code that traps fewer problems
• (blank): compromise between compile time and code speed
• optimized: maximizes speed, at the cost of increased compile time

Note that local options in config/host/$HOST/Makefile and in config/compiler/$HOST/$OPTS.mkf may modify the option bundles.
