source file �� 8M
OS kernel : 32 bit (selecting at installing operating system, the hardware support 64 bit)
when i compiling the large source file (8 M), i encouter the probelm��

If someone have answers to my problem , such as define macro, add compile options , pls tell me . Thanks!!!!!!!
i search the prolem in goole, i find a article . i guess you are right. but how can i do for resolving this register problem .
next is the article , if you have time ,pls help me .
how to compile:
% g++ -maix64 -g -o bigfile2 bigfile2.cc -save-temps -v

This assembler is AIX's assembler.
IBM AIX development team says, this error is not assember's problem:
Problem is with g++ compiler. You are hitting the
hardware limitation. To make it clear consider an opcode
.
ld r4,X(r3);
.
where X will be at most 16 bit.
So irrespective of 64bit or 32 bit object file
we can traverse an offset value of 16 bit.
While creating the assembly listing g++ crossed
the limitation. So assembler throws series of error
messages.
.
Customer can use IBM compiler, which takes care
of this problem and we are not supporting the g++
compiler.
