Module `dmd.backend.cgobj`

Compiler implementation of the D programming language.

Functions

Name	Description
`getindex(p)`	Read index.
`getsegment()`	Allocate a new segment. Return index for the new segment.
`instypidx(p, index)`	Insert a type index number.

`OmfObj_alias(n1, n2)`	Output an alias definition record.
`OmfObj_allowZeroSize()`	Do we allow zero sized objects?
`OmfObj_byte(seg, offset, _byte)`	Output byte to object file.
`OmfObj_bytes(seg, offset, nbytes, p)`	Output bytes to object file.
`OmfObj_codeseg(name, suffix)`	Define a new code segment.
`OmfObj_comdatsize(s, symsize)`	Setup for Symbol s to go into a COMDAT segment. Output (if s is a function): cseg segment index of new current code segment Coffset starting offset in cseg

`OmfObj_data_readonly(p, len, pseg)`	Ouput read only data for data.
`OmfObj_data_start(sdata, datasize, seg)`	Update data information about symbol align for output and assign segment if not already specified.
`OmfObj_dosseg()`	Output DOSSEG coment record.
`OmfObj_ehtables(sfunc, size, ehsym)`	Stuff pointer to function in its own segment. Used for static ctor and dtor lists.
`OmfObj_exestr(p)`	Embed string in executable.
`OmfObj_export_symbol(s, argsize)`	Export a function name.
`OmfObj_external(s)`	Output an external definition.
`OmfObj_far16thunk(s)`	Generate far16 thunk.
`OmfObj_fardata(name, size, poffset)`	Define a far data segment.
`OmfObj_fltused()`	Mark object file as using floating point.
`OmfObj_func_term(sfunc)`	Update function info after codgen
`OmfObj_import(e)`	Convert reference to imported name.
`OmfObj_includelib(name)`	Output library name.
`OmfObj_init(objbuf, filename, csegname)`	Perform initialization that applies to all .obj output files.
`OmfObj_initfile(filename, csegname, modname)`	Initialize the start of object output for this particular .obj file.
`OmfObj_jmpTableSegment(s)`
`OmfObj_ledata(seg, offset, data, lcfd, idx1, idx2)`	Output word of data. (Two words if segment:offset pair.)

`OmfObj_startaddress(s)`	Set start address
`OmfObj_staticctor(s, dtor, seg)`	Symbol is the function that calls the static constructors. Put a pointer to it into a special segment that the startup code looks at.
`OmfObj_string_literal_segment(sz)`	Get segment for readonly string literals. The linker will pool strings in this section.
