Ldf Expressions - Analog Devices VisualDSP++ 3.5 Manual

LDF Expressions

LDF commands may contain arithmetic expressions that follow the same
syntax rules as C/C++ language expressions. The linker:
• Evaluates all expressions as type
stants as type
• Supports all C/C++ language arithmetic operators
• Allows definitions and references to symbolic constants in the LDF
• Allows reference to global variables in the program being linked
• Recognizes labels that conform to these constraints:
• Must start with a letter, underscore, or point
• May contain any letters, underscores, digits, and points
• Are delimited by white space
• Do not conflict with any keywords
