... sounds like ASM_OUTPUT_DEF isn't working correctly with the solaris
assembler. Please try --save-temps and post the .s output.
My guess is that Solaris needs to be fixed to not define ASM_OUTPUT_DEF if the
assembler doesn't support it.

We really need the assembly file to go any further on this bug.

You correctly guessed, it's related to ASM_OUTPUT_DEF and aliases.

The Solaris assembler does support equates (hey! it is not that primitive :-)
but the equated symbol must be defined somewhere in the file. Here we have both
.LL_ZN4java4lang5Class23getDeclaredConstructorsEv13 =
_ZN4java4lang5Class23getDeclaredConstructorsEv
which assembles fine because the second symbol is defined as
.global _ZN4java4lang5Class23getDeclaredConstructorsEv
.type _ZN4java4lang5Class23getDeclaredConstructorsEv, #function
.proc 0110
_ZN4java4lang5Class23getDeclaredConstructorsEv:
and
.LL_ZN4java4lang5Class17getDeclaringClassEv20 =
_ZN4java4lang5Class17getDeclaringClassEv
which doesn't because the second symbol is not defined in the file.
I can think of two explanations:
- the aliased method should have been defined in the assembly file but for some
reason it would not have been used, so the compiler decided to not emit it
altogether,
- the new code in class.c is somehow abusing the notion of "alias" as it
attempts to contruct a local alias of an external function.
In the first case, the fix could be to defer the call to assemble_alias until
after we know that the method will be emitted; in the second case, the fix could
be to add yet another target macro and to guard the new code with it.

Note that while this construct is *accepted* by gas, it won't do what
you might think it would. It does nothing useful. I've wished in the
past that gas would diagnose this problem...

Not much progress. As per RTH's comment, I'll prepare a patch to revert the
faulty bits.

Reverting the change in class.c lets the library build, but only to stumble upon

Reverting the parse.y changes doesn't help. The problem is that the inline
methods defined in java/lang/class.h are not emitted in natClass.o, despite the
presence of
#pragma implementation "Class.h"
at the beginning of the file.

Indeed, relating to the handling of #pragma (PR c++/18075).

Libjava builds for me now on sparc64-sun-solaris2.9 and sparc-sun-solaris2.8.
Testsuite results are decent (42 and 24 failures respectively).
