– changed `inline` to `macro` – added support for parameters for macros written in Millfork – added `inline`, `noinline`, `register` hints – added <<<< operator – pointer dereference expressions are now supported more widely – C64 library fixes – added `-O1` command line option as an alias for `-O`

Function definitions
Syntax:
[<modifiers>] <return_type> <name> ( <params> ) [@ <address>] { <body> }
asm <return_type> <name> ( <params> ) @ <address> extern
-
<modifiers>
: zero or more of the following:-
asm
– the function is written in assembly, not in Millfork (doesn't matter forextern
functions), see Using assembly within Millfork programs#Assembly functions -
macro
– the function is a macro, see Macros_and inlining#Macros -
inline
andnoinline
– the function should preferably/should never be inlined see Macros_and inlining#Inlining -
interrupt
– the function is a hardware interrupt handler
-
-
<return_type>
is a valid return type, see Types -
<params>
is a comma-separated list of parameters, in formtype name
. Allowed types are the same as for local variables. -
<address>
is a constant expression that defines where in the memory the function is or will be located. -
extern
is a keyword than marks functions that are not defined in the current program, but are likely to be available at certain address in memory. Such functions should be marked as written in assembly and should have their parameters passed through registers. -
<body>
is a newline-separated list of either Millfork or assembly statements
