Functions

NameDescription
error(filename, linnum, charnum, format) Insert an index number.
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, reclen) 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_compiler() 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_jmpTableSegment(s)
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)
