relocates the code within this module up by 0x8888 words. The in-line
assembly line:
is equivalent to the C statement ‘ndx += i;’.
The sections.s file is shown below.
.section “text1”, “ax”
.global _foo
_foo:
.section “text2”, “ax”

.walign 2
test_label_1:
.walign 2
test_label_2:
This file declares an external function entry point ‘_foo’ within the
‘text1’ section and two other function entry points ‘test_label_1’ and
‘test_label_2’ within the ‘text2’ section. Since the function ‘int
foo(void)’ is to be called from C, its name must be prefixed with an
underscore.
The slow_pi.s file was generated by the zdcc compiler without
optimizations from a C program. It shows the kind of assembly file
produced by the compiler and gives us the opportunity for demonstrating
the kinds of optimizations zdopt will do. The build script creates the
slow_opt_pi.s file, which is the optimized version of slow_pi.s.
