Similarly there +; are differences between how complete and standard compliant the +; support for these formats are in linkers. +; +; The NASM linker compatibility macros (nasmlcm) were put together +; to ease my work by allowing a single source file to be assembled +; for use with a number of compilers/linkers. +; +; Currently obj/omf, win32/coff, djgpp/coff and elf32 output formats +; are supported. The following macros are available: +; +; lcmtext - section name for the code section +; lcmdata - section name for the initialized data section +; lcmbss - section name for the uninitialized data section +; +; lcmglobal - declare a function (two arguments) or data (one +; argument) as global in the current format +; lcmcglobal - same as lcmglobal, but uses C name decoration +; +; lcmextern - declare a function (two arguments) or data (one +; argument) as extern in the current format +; lcmcextern - same as lcmextern, but uses C name decoration +; lcmdllextern - same as lcmextern, but uses dll name decoration +; lcmwinextern - same as lcmextern, but uses name decoration for +; calling Win32 Api functions (see _MSLIBS_) +; +; lcmimport - declares a function (two arguments) or data (one +; argument) as imported in the current format +; lcmexport - declares a function (two arguments) or data (one +; argument) as exported in the current format +; +; lcmlabel - start label for a function in the current format +; lcmclabel - start label for a function with C name decoration +; lcmadjust - adjust stack after a function call in the current +; format +; lcmret - return from a function in the current format +; lcmcret - return from a C function +; +; The following defines change the format and behaviour: +; +; _ELF_ - the lcm*global macro adds :function and :data type +; specifiers +; +; _OBJ_ - section names are similar to those produced by +; Borland tools to increase compatibility with +; various OMF compatible linkers +; +; _DLL_ - functions are exported and imported with added +; size specifiers (_SomeFunction@12), lcmret adjusts +; stack (stdcall) +; +; _MSLIBS_ - the lcmwinextern macro prepends an underscore and +; adds size specification for functions, allowing +; the object file to be linked with MS libraries. +;
