 See the inline documentation at individual `run_dump_test' procedures in 
`binutils/testsuite/lib/utils-lib.exp', `gas/testsuite/lib/gas-defs.exp' 
and `ld/testsuite/lib/ld-lib.exp', respectively.  Please note the slight 
differences in options according to the tool being tested, and also that 
the dumps need not necessarily be from `objdump', as `readelf' and `nm' 
are also commonly used for output examination.
