assembler: Add a check for when ExecSize and width are 1

Another check (that we hit if we try to use brw_set_src0()). Again,
protect it with the -W option.

assembler: Add a check for when width is 1 and hstride is not 0

The list of region restrictions in bspec do say that we can't have:
     width == 1 && hstrize != 0

We do have plenty of assembly code that don't respect that behaviour. So
let's hide the warning under a -W flag (for now) while we fix things.

11 years agoassembler: Add error() and warn() shorthands and use them in set_src[01]

assembler: Add error() and warn() shorthands and use them in set_src[01]

Now that we have locations, we can write error() and warn() functions
giving more information about where it's going wrong.
