build errors

by JustinGuo＠via-alliance.com

Dear Linaro toolchain support team: I am Justin Guo from S3 graphics Inc. I am studying linaro's big-little codes and is using TC2 Platform. I used ./linaro_kernel_build_cmds.sh to build kernel, I got no problem when I set CONFIG_DEBUG_INFO=y to build for kernel. However, When I trace kernel, the traced line in source code level is jumping up/down, so I tried to turn off the optimization. After modified Makefile as below to turn off optimization: ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE KBUILD_CFLAGS += -Os $(call cc-disable-warning,maybe-uninitialized,) else KBUILD_CFLAGS += -O0 endif I got errors when build linaro kernel for TC2: root@ubuntu:/home/justinguo/linaro/1309# ./linaro_kernel_build_cmds.sh Directory linaro-kernel exists. If the kernel code exists in this directory you may continue without cloning the git repository for the kernel. Are you sure you want to do this? (y/n) y M Makefile HEAD is now at dafe325...

Call for testing QEMU aarch64-linux-user emulation

by Alex Bennée

Hi, After a solid few months of work the QEMU master branch [1] has now reached instruction feature parity with the suse-1.6 [6] tree that a lot of people have been using to build various aarch64 binaries. In addition to the SUSE work we have fixed numerous edge cases and finished off classes of instructions. All instructions have been verified with Peter's RISU random instruction testing tool. I have also built and run many packages as well as built gcc and passed most of the aarch64 specific tests. I've tested against the following aarch64 rootfs: * SUSE [2] * Debian [3] * Ubuntu Saucy [4] In my tree the remaining insns that the GCC aarch64 tests need to implement are: FRECPE FRECPX CLS (2 misc variant) CLZ (2 misc variant) FSQRT FRINTZ FCVTZS Which I'm currently working though now. However for most build tasks I expect the instructions in master [1] will be enough. If you want the latest instructions working their way to mainline you are free to use my tree [5] which currently has: * Additional NEON/SIMD instructions * sendmsg syscall * Improved helper scripts for setting up binfmt_misc * The ability to set QEMU_LOG_FILENAME to /path/to/something-%d.log - this is useful when tests are failing N-levels deep as %d is replaced with the pid Feedback I'm interested in ========================== * Any instruction failure (please include the log line with the unsupported message) * Any aarch64 specific failures (i.e. not generic QEMU threading flakeiness). If you need to catch me in real time I'm available on #qemu (stsquad) and #linaro-virtualization (ajb-linaro). Many thanks to the SUSE guys for getting the aarch64 train rolling. I hope your happy with the final result ;-) Cheers, -- Alex Bennée QEMU/KVM Hacker for Linaro [1] git://git.qemu.org/qemu.git master [2] http://download.opensuse.org/ports/aarch64/distribution/13.1/appliances/ope… [3] http://people.debian.org/~wookey/bootstrap/rootfs/debian-unstable-arm64.tar… [4] http://people.debian.org/~wookey/bootstrap/rootfs/saucy-arm64.tar.gz [5] https://github.com/stsquad/qemu/tree/ajb-a64-working [6] https://github.com/susematz/qemu/tree/aarch64-1.6

linking AArch64 ELF image with aarch64-linux-gnu-ld yields RELASZ = 0

RE: detecting the linaro toolchain via C/C++ preprocessor

by Vermeulen, Michiel

If your code is sensitive to the size of long long, can you use the predefine: __SIZEOF_LONG_LONG__ If that doesn't work, then you can use: gcc -dM -E - < /dev/null to tell you what predefines a gcc compiler has (I would probably look for predefines more specific to what your code is sensitive to than look for a particular compiler). I also wonder a little about your original problem statement since "%lld" should be a way to always print "long long" and if you have a matched set of compiler and library, then it should adjust both together. If you are using "%ld" instead, this works in situations where "long" is the same size as "long long" but may not work when these are different sizes. --mev, Mike Vermeulen

detecting the linaro toolchain via C/C++ preprocessor

by Isidor Zeuner

Hi there! On Linaro gcc 4.6, I am facing an issue due to "long long" integers not being 64 bit as they are on other platforms I'm targeting, which causes different issues, most importantly with printf format strings. I am now circumventing these by using the C/C++ preprocessor in order to choose the right format strings. In order to minimize the necessity for users to manually configure things, I'm wondering if there is a way to detect the Linaro gcc compiler through preprocessor macros. Is this possible? Thanks. Best regards, Isidor

== Progress == * IAS (TCWG-377) - Abandoning softvfp implementation, we should not use it - Both softvfp and dwarf flags went back to kernel/android - Macro issue has been solved, IAS is now Gold! - Still doesn't compile the kernel, though... ;) - Discussions about inline assembly bailing on asm garbage * AArch64 (TCWG-387) - Trying to get the build working and passing tests - Some worries about config.guess updates (license) - Commented out some old JIT tests, they will never work - Memory allocation failures look real bugs, though - At least Five real bugs in test-suite * Background - Patch reviews - Further discussions about Dwarf vs. EH unwind tables - Discussing vectorizer pragmas with GCC list - Reviewing EuroLLVM14 papers - Helping Rob upgrade TCWG Chromebooks * Time - CARD-862 8/10 - Others 2/10 == Plan == * Take a look at Compiler-RT * Check some of the AArch64 errors * Maybe EH/unwind issues * Connect

"invalid expression as operand" in aarch64 inline asm

by Kugan

Hi, I finally got around to checking the attached patch for the https://bugs.launchpad.net/ubuntu/+source/gcc-4.8/+bug/1270789 I noticed attached patch causes regression for pr38151.c in gcc test-suite. A reduced test-case that triggers this is: static unsigned long global_max_fast; int __libc_mallopt (int param_number, int value) { __asm__ __volatile__ ("# %[_SDT_A2]" :: [_SDT_A2] "nor" ((global_max_fast))); global_max_fast = 1; } In this regard I have couple of questions: 1. Is the in-line asm valid? Look ok to me. 2. For the pr38151.c regression, asm diff is as shown below. < add x0, x0, :lo12:.LANCHOR0 < ldr x0, [x0] --- > ldr x0, [x0,#:lo12:.LANCHOR0] This causes: pr38151.c:(.text+0x10c): relocation truncated to fit: R_AARCH64_LDST64_ABS_LO12_NC against `.rodata' collect2: error: ld returned 1 exit status. If I however increase the alignment of .rodata where .LANCHOR0 is defined, this passes. Is alignment of BITS_PER_UNIT valid for SYMBOL_REF? If I change it as I am doing this attached patch, is there anything else I need to do. Thanks, Kugan

linaro/eglibc 2.19

by Khem Raj

Hi Linaro'ites We have upgraded eglibc to 2.19 in OpenEmbedded and I started to notice WARNING: No recipes available for: /home/kraj/angstrom/sources/meta-linaro/meta-linaro-toolchain/recipes-core/eglibc/eglibc_2.18.bbappend NOTE: Resolving any missing task queue dependencies And it seems in this bbappend the SRC_URIs are overridden to point to a Linaro release of eglibc I wanted to know if there is a 2.19 head for linaro eglibc being created ? in that case that bbappend needs fixing too. Thanks -Khem

Re: Reg: Recommended options for aarch64

by Matthew Gretton-Dann

Ganesh, Thank you for your email - please note this question is best directed at linaro-toolchain(a)lists.linaro.org where it is more likely to get picked up quickly. Our general rules for benchmarking are to use -mcpu=cortex-a## -O3 as the compiler flags (where ## is the particular CPU you are interested in). Linaro's philosophy is to try and get the best results possible that normal users will see, we don't go looking for 'magic' options that may give better performance on one benchmark, but not in general. Thanks, Matt On 20 February 2014 09:22, Gopalasubramanian, Ganesh <Ganesh.Gopalasubramanian(a)amd.com> wrote: > Hi, > > We would like to run some benchmarks in the foundation model. > I like to know which is the best option-set (GCC compiler options) that the linaro community recommends for aarch64. > > Regards > Ganesh > -- Matthew Gretton-Dann Linaro Toolchain Working Group matthew.gretton-dann(a)linaro.org

[ACTIVITY] 10-14 FEB 2014

by Kugan

== Progress == - vectorizer (7/10) - Looked into vectorizer target-hooks - enablement of half-float for vectorising; dropped the patch after discussing - Started analysing code generated with unlimited model - gcc 4.8 regression (1/10) - Built Novemnebr and December release (native with system libc) - Ran spec2k fp. Can see regression for ammp with -O3 (with -march=armv7-a and -mthumb) -Started bisecting - Chromebook reset-up (2/10) - SD card died and setup again - Using hdd for gcc testing == Plan == - Check ARMv5 regression for unaligned access - Look into vectorizer cost model/benchmarking
