The information in this article applies to:

  • Microsoft Macro Assembler for MS-DOS, version 5.1, and 5.1a
  • Microsoft Macro Assembler for OS/2, version 5.1, and 5.1a

SYMPTOMS

The assembler will generate bad fixup records for floating point instructions.

An example of this problem is the "FMUL" instruction, which will generate the following fixup record:

FIXUP 

 003:    fixup  seg  rel  offset     offset  0     fixup on 0xde9b
         frame  loc  target ext "FIDRQQ"
The frame method "loc" means Intel frame method number four. This means the fixup frame is the same as the segment of the location.

RESOLUTION

For floating point symbols this is meaningless, particularly in OS/2 and Windows. The frame method should be changed to frame method number five. Frame method number five would make the frame and the target segment the same.

The LINK utility will ignore the frame method.

STATUS

Microsoft has confirmed this to be a problem in MASM versions 5.1, and 5.1a. This problem was corrected in MASM version 6.0.
