Compiler Options
The CC compiler supports all gcc compiler options, in addition to the
SDK-specific options described in
The -mlong_call option is frequently necessary with sdcc because
call-immediates on the ZSP400 architecture have a 13-bit range, and its
use is therefore recommended for applications that are larger than the
range of a call-immediate. The ZSPG2 architecture has a larger call
immediate range (16-bits), so this option is not as critical for it. Better

Description
The compiler generates code for a call instruction using
a register operand. Use this option to resolve the
limitation of the call immediate range.
The compiler disables the assembly optimizer,
sdopt/zdopt/zdxopt. By default, the optimizer is
automatically invoked at optimization levels -O2 and -O3.
No effect. Retained for backward compatibility.
No effect. Retained for backward compatibility.
Enable the compiler to generate mac and macn
instructions without using intrinsics. Use this option only
if the code generated will be run with the sat, q15, sre
and mre bits of %fmode turned off.
Assume data and bss are placed in first 64K words.
(default)
Make no assumptions about data and bss.
Check if stack grows into heap space. If this occurs,
print an error message and halt.
Generate code optimized for the ZSP500 core. (default) zdcc
Generate code optimized for the ZSP600 core.
