GENASSYM.CF(5)                File Formats Manual               GENASSYM.CF(5)

NAME
     genassym.cf - assym.h definition file

DESCRIPTION
     The genassym.cf file is used by genassym(1) to make constant C
     expressions known to assembler source files.  Lines starting with '#' are
     discarded by genassym(1).  Lines starting with include, ifdef, if, else
     or endif are preceded with '#' and passed otherwise unmodified to the C
     compiler.  Lines starting with quote get passed on with the quote command
     removed.  The first word after a define command is taken as a CPP
     identifier and the rest of the line has to be a constant C expression.
     The output of genassym(1) will assign the numerical value of this
     expression to the CPP identifier.  export X is a shorthand for define X
     X.  struct X remembers X for the member command and does a define
     X_SIZEOF sizeof(X).  member X does a define X offsetof(<last struct>, X).
     config <ctype> <gcc constraint> <asm print modifier> can be used to
     customize the output of genassym(1).  When producing C output, values are
     casted to <ctype> (default: long) before they get handed to printf. <gcc
     constraint> (default: n) is the constraint used in the __asm__
     statements. <asm print modifier> (default: empty) can be used to force
     gcc to output operands in different ways then normal. The "a" modifier
     e.g. stops gcc from emitting immediate prefixes in front of constants for
     the i386 and m68k port.
