[Bug preprocessor/21521] -finput-charset -save-temps converts characters twice

[tromey at gcc dot gnu dot org]

I looked at this a bit tonight.

It is straightforward to remove -finput-charset from the second
invocation of cc1 (needed several places -- gcc.c but also the
c++ and objc lang-specs).

I think this approach fails if -combine is used; this is easily
fixed if it is ok to assume that .i files are encoded in the
"internal" charset.

------- Comment #3 from tromey at gcc dot gnu dot org  2006-12-30 23:11 -------
FWIW my initial attempt here, namely inserting %<finput-charset*
into specs in various places, fails if multiple files are given
to gcc when -combine is not used (my patch handles the -combine
case).  This is because the first cc1 invocation removes -finput-charset
from the comand line.
So, some other approach must be found.  Perhaps we can wedge in
another -finput-charset option, or perhaps we can add a special
case of some sort.

[Bug preprocessor/21521] New: -finput-charset -save-temps converts characters twice

[jsm28 at gcc dot gnu dot org]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 1156 bytes --]

Compile the following iso-8859-1 file with -finput-charset=iso-8859-1.  In the
output the string has been converted to UTF-8 as documented.  Compile it with
-finput-charset=iso-8859-1 -save-temps.  In the output the string has been
converted to UTF-8, then that UTF-8 treated as ISO-8859-1 and converted to UTF-8
again, which is incorrect.  If preprocessed output is always in UTF-8 then
preprocessed input must always be treated as in UTF-8 regardless of -finput-charset.

const char s[] = "§";

Compilation time test not requiring execution or scanning assembler:

int a = L'§';

compiled with -finput-charset=iso-8859-1 -save-temps gives a bogus "warning:
character constant too long for its type".
