8.25.

.else

.else

is part of the

as

support for conditional assembly; Section 8.45

.if absolute expression

.

It marks the beginning of a section of code to be assembled if the condition for the preceding

.if

was

false.

8.26.

.elseif

.elseif

is part of the

as

support for conditional assembly; Section 8.45

.if absolute

expression

. It is shorthand for beginning a new

.if

block that would otherwise fill the entire

.else

section.

8.27.

.end

.end

marks the end of the assembly file.

as

does not process anything in the file past the

.end

directive.

8.28.

.endef

This directive flags the end of a symbol definition begun with

.def

.

.endef

is only meaningful when generating COFF format output; if

as

is configured to generate

b.out

, it accepts this directive but ignores it.

8.29.

.endfunc

.endfunc

marks the end of a function specified with

.func

.

8.30.

.endif

.endif

is part of the

as

support for conditional assembly; it marks the end of a block of code that is

only assembled conditionally. Section 8.45

.if absolute expression

.

8.31.

.equ symbol, expression

This directive sets the value of

symbol

to

expression

. It is synonymous with

.set

; Section 8.79

.set symbol, expression

.

The syntax for

equ

on the HPPA is

symbol .equ expression

.

8.32.

.equiv symbol, expression

The

.equiv

directive is like

.equ

and

.set

, except that the assembler will signal an error if

symbol

is already defined. Note a symbol which has been referenced but not actually defined is considered to

be undefined.

Except for the contents of the error message, this is roughly equivalent to

.ifdef SYM

.err

.endif
