dload_<n>

retrieve double from local variables <n> and <n> + 1

Jasmin Syntax

     dload_0 or     dload_1 or     dload_2 or     dload_3 

Stack

Before	After
...	result-word1
	result-word2
	...

Description

Retrieves the double-precision float stored in local variables <n> and <n> + 1 and pushes it onto the operand stack. Both <n> and <n> + 1 must be valid local variable numbers in the current frame, and together they must be holding a double.

See the description of dload for more information on how doubles are retrieved from local variables.

'dload_<n>' is functionally equivalent to 'dload <n>', although it is typically more efficient and also takes fewer bytes in the bytecode.

Example

 dload_0         ; push double in local variables 0 and 1 onto stack dload_1         ; push double in local variables 1 and 2 onto stack dload_2         ; push double in local variables 2 and 3 onto stack dload_3         ; push double in local variables 3 and 4 onto stack 

Bytecode

Type	Description
u1	dload_0 opcode = 0x26 (38)
u1	dload_1 opcode = 0x27 (39)
u1	dload_2 opcode = 0x28 (40)
u1	dload_3 opcode = 0x29 (41)
