I've committed the following patch as obvious. The local "prefix"
variable is only assigned const strings, and only passed to printf()
functions, so add "const" to avoid gcc warnings:
common/sim-fpu.c: In function 'sim_fpu_print_status':
common/sim-fpu.c:2508: warning: initialization discards qualifiers
from pointer target type
common/sim-fpu.c:2566: warning: assignment discards qualifiers
from pointer target type

The local save_data() function takes a pointer to a buffer and only uses it as
the source to the memcpy() function. Since it is given const strings, GCC
likes to spit out warnings:
common/sim-trace.c: In function 'trace_prefix':
common/sim-trace.c:697: warning: passing argument 5 of 'save_data' discards
qualifiers from pointer target type
So I've committed this as obvious.

The sim-options code assigns a const string to "char *" in decoding the
current environment settings, and only uses it to pass to a printf. GCC
outputs the warnings:
common/sim-options.c: In function 'standard_option_handler':
common/sim-options.c:271: warning: assignment discards qualifiers from pointer
target type
common/sim-options.c:272: warning: assignment discards qualifiers from pointer
target type
common/sim-options.c:273: warning: assignment discards qualifiers from pointer
target type
So I've committed this as "obvious".
