According to the datasheet, the C8051F120 has 256 B __idata memory that can be used for the stack. By default, SDCC uses the the 128B __data memory (the lower part half of __idata) for the stack. And indeed, when compiling a program using --model-large --stack-auto, it only uses __data and runs out of stack space soon. SDCC has the --xstack option to place the stack in the 256 B __pdata.
But is using the 256 B __idata for the stack possible in SDCC?
