#useix

#nouseix

Controls whether functions use the IX register as a stack frame reference pointer or the SP (stack pointer)

Note that when the IX register is used as a stack frame reference pointer, it is corrupted when any stack-

variable using function is called from within a cofunction, or if a stack-variable using function contains a

call to a cofunction.

#warns

Syntax: #warns “...”

Instructs the compiler to act as if a serious warning was issued. The string in quotes following the directive

is the message to be printed.

#warnt

Syntax: #warnt “...”

Instructs the compiler to act as if a trivial warning was issued. The string in quotes following the directive

is the message to be printed.

#ximport

Syntax: #ximport “filename” symbol

This compiler directive places the length of filename (stored as a long) and its binary contents at the next

available place in xmem flash. filename is assumed to be either relative to the Dynamic C installation

directory or a fully qualified path. symbol is a compiler generated macro that gives the physical address

where the length and contents were stored.

The sample program ximport.c illustrates the use of this compiler directive.
