When compiling the Rockbox source code as simulator, I encountered the
following bug:

cc1: /build/buildd/llvm-2.2/lib/VMCore/Constants.cpp:1862: static
llvm::Constant* llvm::ConstantExpr::getGetElementPtr(llvm::Constant*,
llvm::Value* const*, unsigned int): Assertion `Ty && "GEP indices invalid!"'
failed.
/home/mcuelenaere/rockbox/apps/plugins/rockboy/save.c:155: internal compiler
error: Aborted
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://developer.apple.com/bugreporter> for instructions.

I attached the preprocessed source as requested.

Same thing on Darwin.
Maurus, llvm-2.2 is quite old at this point, you should get a later version.
Not that it will be bug free (obviously) but will be better.

Dale,

I tried LLVM 2.5 but now I'm getting lots of undefined references to
`__compound_literal.*' in an other file.

Forgot mentioning the specific versions:

That would be PR 3518.  I thought that had been fixed but apparently not.

This is fixed:

I realize Rockbox doesn't compile yet, but I'd like to close this one and track
the other problem under its existing report, PR 3518.

[Quuxplusone]

PR 3518 has been fixed so Rockbox may work now, does it?

I tried to compile the current LLVM SVN version, but failed and didn't really
look into it; I'll try again.

IIUC both bugs manifested in LLVM-GCC and so I only need to build that one,
right?

[Quuxplusone]

That's probably true. Of course other things have changed. It sometimes happens that you need to update llvm as well because the interface between llvm and llvm-gcc has changed; I don't know that that's happened recently, but if you get compile-time errors or something, that's probably why.

[Quuxplusone]

Hi,

Update on this:

I just tested LLVM 2.6 and this compiles the Rockbox simulator just fine!

Thanks,
