[Bug bootstrap/37122] New: fixed-value.c and tree-ssa-loop-ivopts.c won't compile with Sun Studio 11 on Solaris 9 due to incompatible operand types

[davediff at nbcs dot rutgers dot edu]

When trying to compile gcc-4.3.1 using Sun Studio 11 on Solaris 9 I received
the following compilation errors for fixed-value.c and tree-ssa-loop-ivopts.c:

cc -c   -g -DIN_GCC     -DHAVE_CONFIG_H -I. -I. -I../../gcc-4.3.1/gcc

and

In both cases this seems to be occurring because Sun Studio 11 does not like
the types of the operands in the conditional expression. I wrote a patch which
just converts the conditional expression to the equivalent if/else block with
assignment statements. The compiler had no complaints about this. The only
other thing needed to complete the compilation of gcc-4.3.1 using Sun Studio 11
on Solaris 9 was the two patches from bug # 33304

This seems like a bug in Sun's compiler.  As far as I can tell a ? const struct
A : struct A should be valid in C and C++.  I think you should both post the
patches to gcc-patches@ and make sure you file a bug with Sun too.

Yes, your right it is a bug in Sun's Compiler. For those interested it is bug
ID: 6406892. The sun patch that fixes this bug is 121015-06 available here:

I believe 121015-06 is the sparc series.  There is also an x86 variant numbered
121016-07 that fixes the same bugid.  IMHO these patches should be listed in
the solaris-specific installtion instructions here:
http://gcc.gnu.org/install/specific.html#x-x-solaris2
as are the other required solaris patches.

David, would you consider posting a patch for gcc/doc/install.texi ?
Please CC: me if you do so.  Thanks!

updated patch for 4.7.0

I got bitten by this recently. Bootstrapping GCC 4.7.0 on Solaris 8:

I'd love to patch the compiler, but Oracle won't let me do that unless I give
them a fat wad of money. David's patch to the source is no longer applicable to
4.7.0, so I'm attaching an update.
