Targetting the raspberry pi, what triple/flags should I set? I tried triple: armv4t-unknown-linux-gnueabi and ld fails with: a.out uses VFP register arguments if i set hardfloat (using optdata.FloatABIType = FloatABI::Hard), ld fails with an assertion: 2.22 assertion fail ../../bfd/elf32-arm.c:11477 what am I missing?

It depends, of course, what operating system you have installed on the RPi, but given that it's an ARM1176JZFS (ARMv6) chip, I would expect to see armv6, not armv4t, in the CPU part of the triple. It has a VFP unit, so I'd assume that you'd want to set hardfp (unless you installed an OS that doesn't support hardfp in its standard library), but if ld is complaining then you almost certainly have a mismatch.

Hi all, Since the 3.1 testing day is coming and be a ARM tester, I would like to make sure everything is O.K. so that we don't waste the precious time. As discussed on the ML before, I plan to cross compile LLVM/Clang first, then run regression test and test suite on the pandaboards. Could someone help me check to see if I miss something? Thanks! Here is the pandaboard configuration,

Hi Renato, > 1.

Hi Dmitri, You're right. The lli code should be cleaned up. As David said, there was a time when the call to invalidate the instruction cache was necessary. It isn't necessary anymore. -Andy -----Original Message----- From: Dmitri Rubinstein [mailto:dmitri.rubinstein at googlemail.com] Sent: Tuesday, June 04, 2013 7:20 AM To: David Tweed Cc: Kaylor, Andrew; LLVM Dev Subject: Re:

Hi all, There's been some controversies in the TargetTriple changes and I want to explain it better in the list (to a wider audience) and also propose my plans on how to support the ARM platform better, especially cross-compilation in Clang. All this discussion came as a spin-off of bug 8911 (http://llvm.org/bugs/show_bug.cgi?id=8957)... Today we have three major problems in cross-compiling

The attached patch cleans up Opus's x86 intrinsics configury. It: * Makes ?enable-intrinsics work with clang and other non-GCC compilers * Enables RTCD for the floating-point-mode SSE code in Celt. * Disables use of RTCD in cases where the compiler targets an instruction set by default. * Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in
