Module dmd.backend.cgobj

Compiler implementation of the D programming language.


getindex(p) Read index.
getsegment() Allocate a new segment. Return index for the new segment.
instypidx(p, index) Insert a type index number.
objrecord(rectyp, record) Output an object file data record.
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_compiler(p) Embed compiler version in .obj file.
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_ledata(seg, offset, data, lcfd, idx1, idx2) Output word of data. (Two words if segment:offset pair.)
OmfObj_lidata(seg, offset, count) Output an iterated data block of 0s. (uninitialized data only)
OmfObj_linkerdirective(name) Output linker directive.
OmfObj_linnum(srcpos, seg, offset) Line number support.
OmfObj_lzext(s1, s2) Output a lazy extern record. s1 is the lazy extern, s2 is its default resolution.
OmfObj_mangle(s, dest) Mangle a name.
OmfObj_moduleinfo(scc) Append pointer to ModuleInfo to "FM" segment. The FM segment is bracketed by the empty FMB and FME segments.
OmfObj_reftocodeseg(seg, offset, val) Refer to address that is in the code segment. Only offsets are output, regardless of the memory model. Used to put values in switch address tables.

OmfObj_segment_group(codesize, datasize, cdatasize, udatasize) Output segment and group definitions.
OmfObj_setcodeseg(seg) Reset code seg to existing seg. Used after a COMDAT for a function is done.
OmfObj_setModuleCtorDtor(s, isCtor) Set up function to be called as static constructor on program startup or static destructor on program shutdown.
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.
OmfObj_sym_cdata(ty, p, len) Output read only data and generate a symbol for it.
OmfObj_term(objfilename) Terminate package.
OmfObj_termfile() Fixup and terminate object file.
