-bfpack:[tight |
normal |
compatible]
Selects the bit-field packing algorithm. The tight setting produces the most
compact packing, which is the default. The normal setting allocates space in the
structure that corresponds exactly to the declared type of each bit-field. The
compatible
setting produces a packing that is compatible with the less efficient
algorithm that was used before ZDS II release 4.11.0. If you have an older project
that uses both C and assembly code to access bit-fields, you probably need to use
-bfpack:compatible
.
-const:[ram|rom] Selects where const variables are placed. The default is to place const variables in
ram. This is a depreciated option; use the rom keyword instead of const to place
const data in rom.
-cpu: cpu Sets the CPU.
-debug Generates debug information for the symbolic debugger. This is the default.
-define: def Defines a symbol and sets it to the constant value. For example:
-define:myvar=0
The alternate syntax, -define:myvar, is the same as -define:myvar=1.
-fastcall Pass parameters in registers.
-fplib Links with the floating-point emulation library.
-genprintf The format string is parsed at compile time, and direct inline calls to the lower level
helper functions are generated. The default is genprintf.
-help Displays the compiler help screen.
-jmpopt Turns on application of branch optimizations.
-keepasm Keeps the compiler-generated assembly file.
-keeplst Keeps the assembly listing file (.lst).
-list Generates a .lis source listing file.
-listinc Displays included files in the compiler listing file.
-model: model Selects the memory model. Select S for the small memory model or L for the large
memory model. The default is L.
-noasm Does not assemble the compiler-generated assembly file.
-nodebug Does not generate symbol debug information.
-nofastcall Pass parameters in memory.
-nofplib Does not link with floating-point emulation library.
-nogenprint A call to printf() or sprintf() parses the format string at run time to
generate the required output.
-nojmpopt Turns off application of branch optimizations.
-nokeepasm Deletes the compiler-generated assembly file. This is the default.
-nokeeplst Does not keep the assembly listing file (.lst). This is the default.
