[Bug gas/4572] New: division doesn't work on solaris/x86
Hi, Not sure if this is a bug, but the assembler works oddly on solaris x86 as opposed to x86 on (windows,OSX,Linux,*BSD). Essentially, it can't take constant expressions that include division. I am running on an opteron running solaris, and it can't assemble: >cinna>cat tst.s > movq $20/10, %rax >cinna>/usr/local/binutils-2.16.1/x86_64-SunOS-gcc-3.4.2-sun/bin/as --64 -v >>tst.s >GNU assembler version 2.16.1 (i386-pc-solaris2.10) using BFD version 2.16.1 >tst.s: Assembler messages: >tst.s:1: Error: suffix or operands invalid for `movq' But it works fine on any other OS. If this is expected behavior for sparc, what's the reason, and is there any workaround? If it is not expected behavior, any ideas? I support a large libary with many lines like this in it, and so far this keeps me from porting to solaris/x86, even thouth my assembler works on the other x86 platforms.

[Bug gas/4572] division doesn't work on solaris/x86
--- Additional Comments From whaley at cs dot utsa dot edu 2007-05-31 18:01 --- OK, I have established that the problem is that '/' is a comment character under solaris/x86. The Sun assembly ref manual states that \/ should work to perform division in expressions, but this does not work for gnu as. Any idea how to get gas to do division in an integer expression?

--- Additional Comments From whaley at cs dot utsa dot edu 2007-06-01 02:44 --- I can modify the assembly source only by removing functionality. In the original code, it is a cpp macro defined to an integer constant that is being passed in and being divided by known constant. Without being able to do this, I have to switch a compile-time division to a run-time one, which means a mov becomes a long multicycle operation. You are saying there is no way to do division in integer expressions with gas on solaris, even though it works on all other OSes? Isn't that less than ideal?
