    $(P D, being a systems programming language, provides an inline
    assembler.
    The inline assembler is standardized for D implementations across
    the same CPU family, for example, the Intel Pentium inline assembler
    for a Win32 D compiler will be syntax compatible with the inline
    assembler for Linux running on an Intel Pentium.
    )

    $(P Implementations of D on different architectures, however, are
    free to innovate upon the memory model, function call/return conventions,
    argument passing conventions, etc.
    )

    $(P This document describes the x86 implementation of the inline
    assembler.

<h2>Labels</h2>

    $(P Assembler instructions can be labeled just like other statements.
    They can be the target of goto statements.
    For example:
    )

--------------
void *pc;
asm
{
    call L1     ;
 L1:            ;
    pop EBX     ;
    mov pc[EBP],EBX ;   // pc now points to code at L1
}
--------------

<h2>align $(I IntegerExpression)</h2>

$(GRAMMAR
$(GNAME IntegerExpression):
    $(LINK2 lex.html#IntegerLiteral, $(I IntegerLiteral))
    $(I Identifier)
)

    $(P Causes the assembler to emit NOP instructions to align the next
    assembler instruction on an $(I IntegerExpression) boundary.
    $(I IntegerExpression) must evaluate at compile time to an integer that is
    a power of 2.
    )

    $(P Aligning the start of a loop body can sometimes have a dramatic
    effect on the execution speed.
    )

<h2>even</h2>

    $(P Causes the assembler to emit NOP instructions to align the next
    assembler instruction on an even boundary.
    )

<h2>naked</h2>

    $(P Causes the compiler to not generate the function prolog and epilog
    sequences. This means such is the responsibility of inline
    assembly programmer, and is normally used when the entire function
    is to be written in assembler.
    )

<h2>db, ds, di, dl, df, dd, de</h2>

    These pseudo ops are for inserting raw data directly into
    the code.
    $(B db) is for bytes,
    $(B ds) is for 16 bit words,
    $(B di) is for 32 bit words,
    $(B dl) is for 64 bit words,
    $(B df) is for 32 bit floats,
    $(B dd) is for 64 bit doubles,
    and $(B de) is for 80 bit extended reals.
    Each can have multiple operands.
    If an operand is a string literal, it is as if there were $(I length)
    operands, where $(I length) is the number of characters in the string.
    One character is used per operand.
    For example:

--------------
asm
{
    db 5,6,0x83;   // insert bytes 0x05, 0x06, and 0x83 into code
    ds 0x1234;     // insert bytes 0x34, 0x12
    di 0x1234;     // insert bytes 0x34, 0x12, 0x00, 0x00
    dl 0x1234;     // insert bytes 0x34, 0x12, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
    df 1.234;      // insert float 1.234
    dd 1.234;      // insert double 1.234
    de 1.234;      // insert real 1.234
    db "abc";      // insert bytes 0x61, 0x62, and 0x63
    ds "abc";      // insert bytes 0x61, 0x00, 0x62, 0x00, 0x63, 0x00
}

<h3>Special Cases</h3>

     $(B repnz), $(B repz))
    $(DD These prefix instructions do not appear in the same statement
    as the instructions they prefix; they appear in their own statement.
    For example:

--------------
asm
{
    rep   ;
    movsb ;
}
--------------
    )

    $(DT $(B pause))
    $(DD This opcode is not supported by the assembler, instead use

--------------
{
    rep  ;
    nop  ;
}
--------------

    which produces the same result.
    )

    $(DT $(B floating point ops))
    $(DD Use the two operand form of the instruction format;

--------------
fdiv ST(1); // wrong

fmul ST,ST(0);  // right

    $(P The operand syntax more or less follows the Intel CPU documentation
    conventions.
    In particular, the convention is that for two operand instructions
    the source is the right operand and the destination is the left
    operand.
    The syntax differs from that of Intel's in order to be compatible
    with the D language tokenizer and to simplify parsing.
    )

    $(P The $(B seg) means load the segment number that the symbol is
    in. This is not relevant for flat model code.
    Instead, do a move from the relevant segment register.
    )

<h3>Operand Types</h3>

$(GRAMMAR
$(GNAME AsmTypePrefix):
    $(B near ptr)
    $(B far ptr)
    $(B byte ptr)
    $(B short ptr)
    $(B int ptr)
    $(B word ptr)
    $(B dword ptr)
    $(B qword ptr)
    $(B float ptr)
    $(B double ptr)
    $(B real ptr)
)

    $(P In cases where the operand size is ambiguous, as in:)

--------------
add [EAX],3     ;
--------------

    $(P it can be disambiguated by using an $(I AsmTypePrefix):)

--------------
add byte ptr [EAX],3    ;
add int ptr [EAX],7     ;
--------------

    $(P $(B far ptr) is not relevant for flat model code.
    )

<h3>Struct/Union/Class Member Offsets</h3>

    $(P To access members of an aggregate, given a pointer to the aggregate
    is in a register, use the qualified name of the member:
    )

--------------
struct Foo { int a,b,c; }
int bar(Foo *f)
{
    asm
    {   mov EBX,f       ;
    mov EAX,Foo.b[EBX]  ;
    }
}
--------------

<h3>Stack Variables</h3>

    $(P Stack variables (variables local to a function and allocated
    on the stack) are accessed via the name of the variable indexed
    by EBP:
    )

---
int foo(int x)
{
    asm
    {
    mov EAX,x[EBP]  ;  // loads value of parameter x into EAX
    mov EAX,x   ;  // does the same thing
    }
}
---

    $(P If the [EBP] is omitted, it is assumed for local variables.
    If $(B naked) is used, this no longer holds.
    )

<h3>Special Symbols</h3>

    $(DL

    $(DT $(B &#36;))
    $(DD Represents the program counter of the start of the next
    instruction. So,

--------------
jmp $  ;
--------------

    branches to the instruction following the jmp instruction.
    The $(B &#36;) can only appear as the target of a jmp or call
    instruction.
    )

    $(DT $(B __LOCAL_SIZE))
    $(DD This gets replaced by the number of local bytes in the local
    stack frame. It is most handy when the $(B naked) is invoked
    and a custom stack frame is programmed.
    )

    )
