## Test how yaml2obj sets the value of a symbol's st_other fields.

## Show that yaml2obj reports an error when using an STO_* flag that belongs
## to a different machine type to what is specified by the YAML.

# RUN: not yaml2obj --docnum=1 2>&1 %s | FileCheck %s --check-prefix=ERR
# ERR: error: an unknown value is used for symbol's 'Other' field: STO_MIPS_OPTIONAL
