test-suite question, dg-final/scan-file on objects?

[IainS <developer at sandoe-acoustics dot co dot uk>]

Hi,

In the Obj{C,C++} testsuite we have cases where we want to check for  
reasonably long ascii strings in generated data.

At present, this is done in some places by dg-final/scan-assembler  
constructs, but these can (and do) fail when the target assembler  
breaks long strings into shorter concatenated segments.

One solution is target-specific scan-assembler statements, but makes  
the test cases less readable and more prone to maintenance error.

A nicer (and, in a way, more correct) solution would be to use scan- 
file to match for the string in the object.

dg-final/scan-file seems to work on all the targets I've got access  
to...
... however, grep tells me that scan-file is usually used on ".i"  
rather than ".o" files ... so I'd like to ask:

"Is it an accepted approach to use scan-file on objects? "  ... or
"Is there an equivalent to scan-file specifically targeted at  
objects?" (nothing leaps out at me in the doc./google)

cheers
