[llvm-dev] lld-link with MSVC6 object files

[Alexandre Ganea via llvm-dev]

The CodeView library in LLVM only supports Codeview C13 types, that is, MSVC 7.0 / Visual Studio 2002 or after.

MSVC 6 as in the Visual Studio released in 1989? Yes, I imagine that's a bit outside the intended support window.

Hi,

I have a question about lld-link. What obj file formats should it support? When I try to use an obj from msvc 6.0 it complains that the file magic is not valid.

However when running  llvm-objdump it reports:


test1.obj:      file format COFF-i386

Disassembly of section .text:
0000000000000000 _main:
       0:       68 00 00 00 00  pushl   $0
       5:       e8 00 00 00 00  calll   0 <_main+0xa>
       a:       83 c4 04        addl    $4, %esp
       d:       33 c0   xorl    %eax, %eax
      f:       c3      retl

Thanks,
Paul
