           Summary: Asm broken on IA64 ?
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: wwadge at hobsoft dot com dot mt
                CC: gcc-bugs at gcc dot gnu dot org

In my .S file, I have the following:
movl r25=(1 << 64) - 1

assembling and objdump'ing gives movl r25=0x0 instead of 0xffffffff as
I'd expect. 

I'm running on IA32 and generating code for IA-64.

This problem was not evident in 2.96 (yes from Redhat I know, sorry)

Not a gcc bug but a binutils bug (they control gas, the assembler) report it to them.

This isn't a binutils bug either.  Shifting by greater than the size of 
int is invalid.  Changing this to 1L << 64 doesn't help, because you are 
still shifting by greater than the size of long.
