             Bug #: 15034
           Summary: MOVABS fails in intel syntax, good in att. Behavior
                    mismatch intel vs att syntax
           Product: binutils
           Version: 2.23
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


GNU assembler version 2.23.1 (x86_64-linux-gnu) using BFD version (GNU
Binutils) 2.23.1

Sorry for my english.

My assembly code generated by GCC 4.7.2 from cpp source. Assembly code and cpp
are 100% correct. Error in GAS code analiser, which stick on nonexistent error.
The error appear only while used intel syntax (gcc -masm=intel) and do not
appear with default (att) syntax (without -masm=intel).

The c++ code which introduces error:
*(volatile int*)0xFEE00000;

Command line:
x86_64-linux-gnu-gcc -c -Wall -Wno-attributes -save-temps -fverbose-asm
-masm=intel -march=core2 -mcmodel=large -mno-mmx -mno-sse -O1 -fno-rtti
-fno-default-inline -fomit-frame-pointer -falign-functions=16
-foptimize-sibling-calls -ffreestanding -fno-stack-protector --no-exceptions
Boot64.cpp

Screen output:
Boot64.s: Assembler messages:
Boot64.s:91: Error: operand type mismatch for `movabs'
