3.7.6. Asm68k Debugging Directives
Debugging directives are used to generate source-level debugging information.
They are typically generated by the Sierra Systems C compiler to allow
source-level debugging, but can also be used when programming in assembly
language. Table 3.29 summarizes the debugging directives for
asm68k
.
The debugging directive descriptions are provided primarily to facilitate
interpreting the compiler-generated directives. Their use is not recommended for
programs written in assembly language. Instead, the
-L
command line flag
should be used in conjunction with the
.type
directive to provide a reasonable
level of debugging capability. When the
-L
command line flag is specified, a line
number entry is generated for each instruction and memory allocation directive in
text-type sections.
