[ANNOUNCE] Linaro QEMU 2012.05 released

2012-05-17 Thread Peter Maydell 
The Linaro Toolchain Working Group is pleased to announce the release of
Linaro QEMU 2012.05.

Linaro QEMU 2012.05 is the latest monthly release of qemu-linaro. Based
off upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes
and enhancements.

New in this month's release:
 - Beagle bootrom emulation now correctly handles FAT12/FAT16
   images (thanks to Peter Chubb for the bug report and patch).
 - We now support running ARM BE8 userspace binaries (ie
   byte-invariant big-endian data and little-endian code).

Known issues:
 - Graphics do not work for OMAP3 based models (beagle, overo)
  with 11.10 Linaro images.
 - Audio may not work on Versatile Express models with the latest
 Linaro kernel/hardware packs (LP:977610).

The releases have been made, so the branches have been updated and 
returned to their normal state.

 The root cause is target vect_cmdline_needed. For those cases, they
 have notes as:

 /* { dg-do run { target vect_cmdline_needed } } */

 In function check_effective_target_vect_cmdline_needed of
 lib/target-supports.exp, it check_effective_target_arm_neon.

 For our build, it is arm neon,
 check_effective_target_vect_cmdline_needed return 0.

 A quick fix is to add another dg-do run like:
 /* { dg-do run { target arm*-*-*eabihf } } */

I've looked into this further and the tests make no sense.  The test
themselves are turned off unless the compiler needs extra command line
arguments to enable some type of SIMD.  See PR21292.  Let's discuss
this on Monday.

I've put an updated list at:
 http://people.linaro.org/~michaelh/incoming/hard-float-builder-diff-2.txt

The interesting ones below.  They're a mix of assembler faults, ICEs,
and testisims.  None are due to the change in triplet so please
propose your patch upstream.
