/* The Sun acc compiler, under SunOS4, puts out
functions with N_GSYM or N_STSYM. The problem is
that the address of the symbol is no good (for N_GSYM
it doesn't even attept an address; for N_STSYM it
puts out an address but then it gets relocated
relative to the data segment, not the text segment).
Currently we can't fix this up later as we do for
some types of symbol in scan_file_globals.
Fortunately we do have a way of finding the address -
we know that the value in last_pc_address is either
the one we want (if we're dealing with the first
function in an object file), or somewhere in the
previous function. This means that we can use the
minimal symbol table to get the address. */
/* Starting with release 3.0, the Sun acc compiler,
under SunOS4, puts out functions with N_FUN and a value
of zero. This gets relocated to the start of the text
segment of the module, which is no good either.
Under SunOS4 we can deal with this as N_SLINE and N_SO
entries contain valid absolute addresses.
Release 3.0 acc also puts out N_OPT entries, which makes
it possible to discern acc from cc or gcc. */
