           Summary: "add ebx, OFFSET FLAT:_GLOBAL_OFFSET_TABLE_" is
                    incorrectly assembled
           Product: binutils
           Version: 2.21 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
        AssignedTo: address@hidden
        ReportedBy: address@hidden


address@hidden pr46275]$ cat p.c
#include <stdio.h>
int main()
{ puts("Hello, world!"); return 0; }
address@hidden pr46275]$ make
gcc -m32 -masm=intel -fPIC -S p.c
gcc -m32 -o p p.s
./p

address@hidden pr46275]$ 

For some reason, the addend in R_386_GOTPC reloc is missing when compiled with
-masm=intel. The objdump difference between -masm=att [hello.o] that works and
-masm=intel [hello_.o] that fails is:
