3.2.4 MCS51 Options
- [--model-small] Generate code for Small Model programs, see section Memory Models
for more details. This is the default model.
- [--model-medium] Generate code for Medium model programs, see section Memory Models
for more details. If this option is used all source files in the project
have to be compiled with this option. It must also be used when invoking
the linker.
- [--model-large] Generate code for Large model programs, see section Memory Models
for more details. If this option is used all source files in the project
have to be compiled with this option. It must also be used when invoking
the linker.
- [--xstack] Uses a pseudo stack in the pdata area (usually the first 256 bytes in the external ram) for allocating
variables and passing parameters. See section
External Stack for more details.
- [--iram-size <Value>] Causes the linker to check if the internal ram usage is within
limits of the given value.
- [--xram-size <Value>] Causes the linker to check if the external ram usage is within
limits of the given value.
- [--code-size <Value>] Causes the linker to check if the code memory usage is within
limits of the given value.
- [--stack-size <Value>] Causes the linker to check if there is at minimum <Value> bytes
for stack.
- [--pack-iram ] Causes the linker to use unused register banks for data variables
and pack data, idata and stack together. This is the default now.
- [--no-pack-iram ] Causes the linker to use old style for allocating memory areas.
- [--acall-ajmp ] Replaces the three byte instructions lcall/ljmp with the two byte
instructions acall/ajmp. Only use this option if your code is in the
same 2k block of memory. You may need to use this option for some
8051 derivatives which lack the lcall/ljmp instructions..
