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).

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(https://wiki.linaro.org/Cycles/Next/Release/Status) which seems even more out-of-date than the Launchpad binaries; perhaps that link should be updated/removed, too.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

[ANNOUNCE] Linaro GCC 4.9 2014.07 released

by Yvan Roux

The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.07 stable release of the Linaro GCC 4.9 source package. Linaro GCC 4.9 2014.07 is the fourth Linaro GCC source package release in the 4.9 series. It is based on FSF GCC 4.9.1+svn212419 and includes performance improvements and bug fixes. With the imminent release of ARMv8 hardware and the recent release of the GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and performance of the compiler as the FSF GCC compiler approaches version 4.9.1. The Linaro TCWG will provide monthly stable[1] source package releases until FSF GCC 4.9.1 is released. At that point Linaro GCC 4.9 will merge in FSF GCC 4.9.1 and, release Linaro GCC 4.9.1, and then return to a schedule of stable quarterly releases and monthly engineering[2] releases. Interesting changes in this GCC source package release include: * Updates to GCC 4.9.1-pre+svn212419 * Backport of [AArch32] Wrap long literals in HOST_WIDE_INT_C in aarch-common.c * Backport of [AArch32] Rewrite TLC Intrinsics. * Backport of [AArch32] Remove vzip, vuzp, vtrn builtins and cleanup * Backport of [AArch32] Use enum name instead of integer value for PARAM_SCHED_PRESSURE_ALGORITHM. * Backport of [AArch32] Vectorise bswap* * Backport of [AArch32] Fix PR/61331 * Backport of [AArch32] Fix PR target/61154 * Backport of [AArch32] Use mov_imm type for movw operations consistently * Backport of [AArch32] Remove XFmode from ARM backend. * Backport of [AArch64] Rewrite REV Intrinsics. * Backport of [AArch64] Implement HARD_REGNO_CALLER_SAVE_MODE. * Backport of [AArch64] Support tail indirect function call. * Backport of [AArch64] Fix stack protector for ILP32 * Backport of [AArch64] ILP32 dynamic linker * Backport of [AArch64] Correct signedness of builtins, remove casts from arm_neon.h * Backport of [AArch64] clarify stack layout diagram * Backport of [AArch64] Implement movmem for the benefit of inline memcpy * Backport of [AArch64] Fix REG_CFA_RESTORE mode. * Backport of [AArch64] Fix layout of frame layout code. * Backport of [AArch64] Fix some reg-to-reg move scheduler types. * Backport of [AArch64] Implement CRC32 ACLE intrinsics + testsuite. * Backport of [AArch64] Implement ADD in vector registers for 32-bit scalar values. * Backport of [AArch32/AArch64] TARGET_ATOMIC_ASSIGN_EXPAND_FENV AArch64 * Backport of [AArch32/AArch64] Use signed chars in gcc.dg/pr60114.c. * Backport of [AArch32/AArch64] Rewrite UZP Intrinsics. * Backport of [AArch32/AArch64] Rewrite TRN Intrinsics. * Backport of [AArch32/AArch64] Rewrite EXT Intrinsics. * Backport of [genattrtab] Fix memory corruption, allocate enough memory for all bypassed reservations * Backport of Fix PR c/60114 Feedback and Support Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. ** Linaro Toolchain Development "mailing list": http://lists.linaro.org/mailman/listinfo/linaro-toolchain ** Linaro Toolchain IRC channel on irc.freenode.net at @#linaro-tcwg@ * Bug reports should be filed in Launchpad against "Linaro GCC project": http://bugs.launchpad.net/gcc-linaro/+filebug. * Questions?

linaro prepackaged binary for aarch64 static libfdt.a?

by Claudio Fontana

Hello Will and list, do you have a prepackaged static libfdt.a for aarch64? I think it's part of some of the released images you provide, but maybe you have it also available as a single package? Thank you, Claudio
