Hi guy, In order to have soft-float support in toolchain, I tried to build our toolchain using Linaro ct-ng script. I used "linaro-armeb-linux-gnueabihf" configuration then change floating point option from hard to soft. There is the error I have: [ERROR] /projects/broadcom-linux/joelz/r/linaro-gcc-build/.build/armeb-linux-gnueabi/build/gcc-core-shared/lib/gcc/armeb-linux-gnueabi/4.8.3/../../../../armeb-linux-gnueabi/bin/ld: error: /projects/broadcom-linux/joelz/r/linaro-gcc-build/.build/armeb-linux-gnueabi/build/gcc-core-shared/lib/gcc/armeb-linux-gnueabi/4.8.3/libgcc.a(bpabi.o) uses VFP register arguments, /projects/broadcom-linux/joelz/r/linaro-gcc-build/.build/armeb-linux-gnueabi/build/build-libc/elf/librtld.map.o does not For short, libgcc.a(bpabi.o) uses VFP register arguments, but librtld.map.o does not. The C library used is eglibc version (Linaro 2.19-2014.04), is this a way to make eglibc work with sfot-float? Thanks! Joel

No arm-eabi builds on latest Linaro Android 4.9 toolchain?

by 박주형

I was using arm-eabi builds on Linaro Android 4.9 toolchain 2014.06. I've just downloaded 2014.07 and found out there is not an arm-eabi toolchain. I need arm-eabi to build Linux kernels and arm-none-eabi toolchain from here: http://releases.linaro.org/14.07/components/toolchain/binaries/gcc-linaro-a… is not capable of building LTO kernels. Error pops up : "cc1: error: -fno-fat-lto-objects are supported only with linker plugin" TL;DR, I need arm-eabi builds from Linaro Android toolchains. arm-none-eabi builds are not built with linker plugin enabled.

Linaro toolchain binary allowing soft-float?

by Joel (Xi Zhou) Zhou

Hi Linaro-toolchain team, I notice that the Linaro toolchain binary only support hard-float. We have a platform which is ARMv7 based does not support VFP. Could you generate toolchain binary for ARmv7 that allows soft-float? Thanks, Joel

help, here is a armV8 32bit question for linaro 4.8: the code I given below adopt sembedding ARMV8 assembly , but the compile result with Linaro GCC 4.8 aarch32 is not correct

by Panshilin (Peter)

Hi all concerned: this test code I given below: AARCH32 [https://email-cn04.huawei.com/owa/14.3.158.1/themes/base/pgrs-sm.gif] Test function[X][X] { volatile unsigned int val0 = 0; volatile unsigned int val1 = 0; asm volatile(“mrrc p15, 1, %0, %1, c15” : “=r”(val0), “=r”(val1)) val0 &= ~(1<<6); val1 &= ~(1<<6); asm volatile(“mcrr p15, 1, %0, %1, c15” : “=r”(val0), “=r”(val1)); } After compiling, the result is: mrrc 15, 1, r2, r3, cr15 str r2, [fp, #-28] str r3, [fp, #-24] ldr r3, [fp, #-28] bic r3, r3, #64; str r3, [fp, #-28] ldr r3, [fp, #-24] bic r3, r3, #64 str r3, [fp, #-24] mcrr 15, 1, r2, r3, cr15 obviously , it is not what I expect. I have val0 an vl1 two vars, but the compiling result is only one val takes effect. especia I have to mention is AARCH32. thanks. Peter

FW: Request received: accessing toolchain source releases - Member user

by Scott Douglass

Hi, Do you happen to know the answer to the git/svn questions below? Thanks. -----Original Message----- From: LDTS [mailto:support@linaro.zendesk.com] Sent: 25 July 2014 08:43 To: Scott Douglass Subject: Request received: accessing toolchain source releases - Member user Thank you for contacting Linaro. Your request (#927 <https://support.linaro.org/requests/927> ) has been received and is being reviewed by Linaro Developer Technical Support (LDTS). One of our Support agents will be in contact with you as soon as possible. If you would like our agent to contact you via phone, please include your phone number in the comments. To view your ticket and/or add additional comments, reply to this email or click the link below: http://support.linaro.org/requests/927 Scott Douglass Jul 25 16:43 Hi, I’ve been looking at https://wiki.linaro.org/WorkingGroups/ToolChain (https://wiki.linaro.org/WorkingGroups/ToolChain) and I see the Tree links that give me the git repository and commit id for the current releases of the toolchains (for example, 4.9-2014.06-1 => https://git.linaro.org/toolchain/gcc.git/commit/56d9fd9281e8cef3ea35b7d9ad8… (https://git.linaro.org/toolchain/gcc.git/commit/56d9fd9281e8cef3ea35b7d9ad8… My first question is: is there a straight-forward way (for example, a tag) to find the commit ids of older (4.9) releases? Or is searching the commit messages the best way? Also, is there svn access as well or just git access? (Git access is enough, but svn access would be slightly easier for me.) Also, I has a couple comments on that wiki page: It says “Pre-built versions that run on generic Linux or Windows are available at http://launchpad.net/linaro-toolchain-binaries.”, but it looks like the that Launchpad project is no longer being maintained (no 4.9 and no recent 4.8). Perhaps the wiki page should be updated (and the Launchpad description updated). The wiki page also links to https://wiki.linaro.org/Cycles/Next/Release/Status (https://wiki.linaro.org/Cycles/Next/Release/Status) which seems even more out-of-date than the Launchpad binaries; perhaps that link should be updated/removed, too.

VFP in BE mode - undefined instruction vstmia

by Joel (Xi Zhou) Zhou

Hi all, I'm working on booting Linaro LSK 3.10.40 kernel in be8 mode on our Cortex-A9 system. There is an issue related to VFP instruction. It complain "vstmia" is an undefined instruction. The VFP is supported in CPU and CONFIG_VFP and CONFIG_VFPv3 are enabled in kernel config. Are there any patch need to be done for VFP in BE mode? The booting log show as following: call sys_access(/init) Freeing unused kernel memory: 2832K (c0600000 - c08c4000) kernel_init: try to execute '/init' (ramdisk_execute_command) en->run_init_process(/init) init (1): undefined instruction: pc=0000aab8 Code: f00f dff8 2a20 1268 (acec) 108b Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 The disassembly code show the undefined instruction is "vstmia". armeb-linux-gnueabihf-objdump -D busybox_unstripped > busy.asm 0000aa90 <__sigsetjmp>: ... aab6: 6812 ldr r2, [r2, #0] aab8: ecac 8b10 vstmia ip!, {d8-d15} aabc: f412 7f00 tst.w r2, #512 ; 0x200 The rootfs is busybox 1.22.1 compiled by Linaro BE hard floating toolchain. https://releases.linaro.org/14.04/components/toolchain/binaries/gcc-linaro-… Thanks, Joel

== Progress == * Recovered from flu on leave 7th and 8th July (4/10) =LTO bootstrap -tcwg180 (2/10)= Git bisect experiments shows bootstrap compare errors apprearing and disappearing at trunk at different revisons. Alteast 3 revisons LTO bootstrap passes r210740 2488876068f541a341472c3aeedadccc255f0696 PASS r210854 271fe9cf111f6b581451bbfb4d346757877896cd PASS r210973 487fea840105dbb0ff516b797e7d86bea82ef74a PASS It is hard to do backport of revisons which fixes this bug. Need to discuss with LTO people in GCC mailing list =Reload spill fix -tcwg180 (2/10)= Emailed my status on benchmarking https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00450.html This bug cannot be fixed without performance degradation. So if it cannot be up streamed, the reporter can use the patch to build his package atleast. Planning to close this bug if I did not receive any comments from maintainers. =Misc (2/10)= * GCC internal team meeting * Meeting with Ryan == Plan == * Benchmark coremark -O3 vs -O3 -flto. * Email to marcus on ABI for large memory model in Aarch64. * Cauldron preparation. == Planed leaves == * Jul 18- 25: Travel to Cambridge.
