Hi,
At this point I think we've fixed basically all the -Wwrite-strings issues in
gas that can be fixed reasonably without just adding casts. So this series
adds a handful of casts in several patches that try to explain why those casts
are necessary, and then enables the warning for gas.
I built one target per tc-*.c and regtested x86_64-linux-gnu, ok?
Trev
Trevor Saunders (7):
cast literal to char * when assigning to input_line_ptr
work around get_symbol_name () in sparc and ia64
cast to char * when assigning to optarg
cast the arg to md_assemble () to char *
tc-i960.c: add some casts when assigning literals to args[i]
make xtensa_section_rename () take const char *
enable -Wwrite-strings for gas

parse_ldconst () takes a char ** as a in / out argument, and sometimes points
args[0] to a constant string. Then in some cases after parse_ldconst ()
returns md_assemble () twiddles the contents of arg[0]. So it seems like
it would take some work to avoid these casts, and its not really clear
that work is worth it.

We add a new AC_SUBST to warning.m4 so that the test if the warning is
supported is centralized, but the warning can be enabled per directory.

various places either directly or indirectly set input_line_pointer to point at
a literal. Currently lots of places modify the string input_line_pointer
points at, so making it const isn't easy. Since most if not all of these
places assign to input_line_pointer to parse an expression it would probably be
best to add ways to generate and deal with expressions that doesn't involve
parsing strings, but for now adding some casts seems easiest.

get_symbol_name () returns a char * in a out arg, which means we need to cast
to assign a literal to the variable passed to get_symbol_name (). It seems
like better APIs than get_symbol_name () could be provided, but that seems like
a fair amount of work so just casting seems to be the betterthing to do for
now.

Xtensa uses it in several macros passing it a literal string, so its convenient
for the argument type to be const char *. However some of the code in
symbols.c seems to assume tc_canonicalize_symbol_name () will return a non
const pointer, and some other target's implementations even modify the
argument, so it seems best to return a char * which means casting away const on
the argument when we return it instead of another string.

For these targets its not clear how md_assemble can usefully be split up so
that part can take const char *. There is also a fair number of targets that
need md_assemble () to take a char *, so we can't easily make the argument
const. So since there isn't many callers it seems easiest to just add a couple
of casts.

bleh, it looks like asintl.h does

I'm not sure what is going on, and would have to build a compiler that
old, but it doesn't seem to make much sense. According to
https://gcc.gnu.org/onlinedocs/gcc-4.0.4/gcc/Warning-Options.html#Warning-Options
-Wwrite-strings was supported in gcc 4.0, so presumably your gcc 4.4.5
should accept it.

Sorry it was not this patch but rather the one which enable
-Wstack-usage one. For some reason my mail client pointed to this
patch that added that.

Hi Andrew,

Is this still a problem ?
The -Wstack-usage patch now only enables the option with a gcc
version 5 or higher, so I believe that it should work, even in
a Canadian cross build.
Cheers
Nick
