I am using MASM's COFF object files with Djgpp (RHIDE ) and am getting a
strange error while calling the coff file from a c program in the RHIDE
env.
this is the MASM assembly file
.386
.MODEL FLAT
.DATA
VAR1 DW 0
VAR2 DW 0
.CODE
_xmain PROC NEAR
MOV AX,0ffffh
MOV VAR2,AX
MOV VAR1,AX
RET
_xmain ENDP
END
now when i use this function from rhide and read the contents of the
disassembler window
i can see the following code
MOV %ax,VAR1
MOV %ax,VAR1
VAR2 store is getting transformed into a VAR1 store!!
WHY??????
Please help me out. A BIG LOAD OF THANX in advance.
