Modest

Compiler usage

Example:

# For translation main.cm to main.c, just type
mcc -omain -mbackend=c main.cm

Compiler flags

Output flag

Use -o<output_file_name> option for set output file name (without file extension)

Usage example:

mcc -o main main.cm

Feature flags

Use -f<feature_name> flag for enable some compiler options

-funsafe - Enables unsafe mode when:

• You can cast pointer to another pointer
• You can do pointer arithmetics (only with FreePointer type value)

-fparanoid - Every warning becomes error

Usage example:

mcc -o main -fparanoid main.cm	   # warnings as errors
mcc -o io -fparanoid -funsafe io.cm  # warnings as errors + unsafe mode

Modifier flags

Use -m<varname>=<value> option to change compiler settings

***-fbackend=*** - backend switching

Usage example:

mcc -o main -mbackend=c  main.cm     # use C backend for translation to main.c
mcc -o main -mbackend=cm  main.cm    # use Modest backend for translation to main.cm
mcc -o main -mbackend=llvm  main.cm  # use LLVM backend for translation to main.ll
