The following is a bug report for gas-1.25. This was made from gas-1.24
and applying a patch sent to me modifying write.c for VMS systems to get
gas-1.25.
bug-gcc@prep.ai.mit.edu
To whom it may concern,
The following bugs where found at my site involving the GNU as assembler.
The versions of GNU used are:
gcc version 1.24
Gnu assembler version 1.25 (I guess.)
While this problem is with the GNU as assembler,
I am including information about the GNU CC and my system.
My system is a CRDS (Charles Rivers Data Systems) CP20 (68020 & 68881) UNOS 7.1
(SYSV) Unix system. I have 4.0 Mbytes of memory. The "tm.h" and "md.h" are
essentially sun3 stuff but I modified "tm.h" to conform to my system. "md.h"
is a shipped (i.e. md-m68k.h).
The problem that I have is with gas-1.25. I took the messages.c module from
the source release of gas-1.25 and compiled it to the assembly language level.
With my old gas-1.14, this module will compile fine. However, with gas-1.25,
I get:
messages.s:89:FATAL:a68: 2nd pass not implemented - get your code from random(3)
This is not a nice error message, especially from something that used to work.
I guess my question is: Is the newer gcc compiler necessary? Does the newer
compiler generate different enough code that gas operation would be different?
Will Roger Rabbit ever get out of his mess?
Below is the output of my gcc-1.24 for messages.c:
gnugcc -I. -g -O -Dmc68851 messages.c -S
