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: unassig...@sourceware.org
ReportedBy: akob...@mail.ru
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'
