nothrow @nogc @trusted voiddt_free(dt_t*dt);

Free a data definition struct.

nothrow @nogc @safe voiddt_term();

Free free list.

nothrow @nogc @safe voiddtpatchoffset(dt_t*dt, uintoffset);

nothrow @nogc @safe voidinit_common(Symbol*s);

Make a common block for s.

nothrow @nogc @safe uintdt_size(const(dt_t)*dtstart);

Compute size of a dt

nothrow @nogc @safe booldtallzeros(const(dt_t)*dt);

Return true if dt is all zeros.

nothrow @nogc @safe booldtpointers(const(dt_t)*dtstart);

Return true if dt contains pointers (requires relocations).

nothrow @nogc @safe voiddt2common(dt_t**pdt);

Turn DT.azeros into DTcommon

structDtBuilder;

nothrow @safe voidcheckInitialized();

Useful for checking if DtBuilder got initialized.

nothrow @safe voidprint();

Print state of DtBuilder for debugging.

nothrow @safe dt_t*finish();

Finish and return completed data structure.

nothrow @safe voidnbytes(const(char)[]ptr); nothrow @trusted voidnbytes(const(ubyte)[]data);

Append data represented by ptr[0..size]

nothrow @trusted voidabytes(tym_tty, uintoffset, const(char)[]data, uintnzeros, ubyte_align);

Write a reference todata withnzeros zero bytes at the end.

Parameters:

tym_t`ty`	pointer type
uint`offset`	to be added to offset of data generated
const(char)[]`data`	data to write
uint`nzeros`	number of zero bytes to add to the end
ubyte`_align`	log2() of byte alignment of pointed-to data

nothrow @trusted voiddword(intvalue);

Write 4 bytes of value.

nothrow @trusted voidsize(ulongvalue);

Write a size_t value.

nothrow @safe voidnzeros(size_tsize);

Write a bunch of zeros

nothrow @trusted voidxoff(Symbol*s, uintoffset, tym_tty);

Write a reference to s+offset

nothrow @safe voidxoff(Symbol*s, uintoffset);

Create reference to s+offset

nothrow @trusted dt_t*xoffpatch(Symbol*s, uintoffset, tym_tty);

Like xoff(), but returns handle with which to patch 'offset' value.

nothrow @safe Symbol*dtoff(dt_t*dt, uintoffset);

Create a reference to another dt.

Returns:

the internal symbol used for the other dt

nothrow @trusted voidcoff(uintoffset);

Write reference to offset in code segment.

nothrow @safe voidcat(dt_t*dt);

Append dt to data.

nothrow @safe voidcat(ref DtBuilderdtb);

Append dtb to data.

nothrow @trusted voidrepeat(dt_t*dt, size_tcount);

Repeat a list of dt_t's count times.

nothrow @safe uintlength();

Return size of data.

nothrow @safe boolisZeroLength();

Return true if size of data is 0.

nothrow @nogc @safe dt_t*dt_get_nzeros(uintn);

Temporary hack to initialize a dt_t* for C.
