.Bcond

The assembler expands a .Bcond directive into instructions

Remark

.BT, .BF, .BC, .BNC, .BZ, .BNZ, .BH, and .BNH are collectively called .Bcond.

[Syntax]

Symbol field	Mnemonic field	Operand field	Comment field
	.Bcond	label	[; comment]

-	In the above syntax, .BC, .BNC, .BZ, .BNZ, .BH, and .BNH can be specified as .Bcond. A label can be specified in the form of !LABEL, $!LABEL, or !!LABEL.

Symbol field	Mnemonic field	Operand field	Comment field
	.Bcond	bit-term, label	[; comment]

-	In the above syntax, .BT, and .BF can be specified as .Bcond. A label can be specified in the form of !LABEL, $!LABEL, or !!LABEL.

Symbol field	Mnemonic field	Operand field	Comment field
	.Bcond	label1, label2	[; comment]

-	In the above syntax, .BC, .BNC, .BZ, .BNZ, .BH, and .BNH can be specified as .Bcond. For label1 and label2, the following combinations are allowed.

Label1	Label2
!LABEL1	$LABEL2
!LABEL1	!LABEL2
$!LABEL1	$LABEL2
$!LABEL1	$!LABEL2
$!LABEL1	!!LABEL2
!!LABEL1	$LABEL2
!!LABEL1	$!LABEL2
!!LABEL1	!!LABEL2

Symbol field	Mnemonic field	Operand field	Comment field
	.Bcond	bit-term, label1, label2	[; comment]

-	In the above syntax, .BT, and .BF can be specified as .Bcond. For label1 and label2, the following combinations are allowed.

Label1	Label2
!LABEL1	!LABEL2
$!LABEL1	$!LABEL2
$!LABEL1	!!LABEL2
!!LABEL1	$!LABEL2
!!LABEL1	!!LABEL2

[Function]

-	The assembler expands a .Bcond directive into instructions.

-	The .Bcond directive is provided to be output by the compiler; the user must not use this directive.

[Description]

-	.Bcond directives are generated by the compiler, and the assembler expands them as follows. Ncond indicates a condition opposite to cond.

Before Expansion	After Expansion
.Bcond label	SKNcond BR label
.Bcond bit-term	BNcond bit-term, $temp BR label temp:
.Bcond label1, label2	SKNcond BR label1 BR label2
.Bcond bit-term, label1, label2	Bcond bit-term, $temp BR label2 temp: BR label1
