ASAN/TSAN run on 42 bit VA Aarch64 with 64 bit allocators (TCWG-634) (6/10) * Juno does not have space for kernel allocator map demanded by ASAN, So we need to remain on 32 bit allocators only. * amd-01 went offline. So moved to internal machine in AMD. Debugging LLVM test failures in GDB showed that ASLR should be turned off and also the shadow offset is set at 1<<36 and is not changing when I fix it in asan_mappings.h file . Manually changing shadow offset to 1<<39 fixes some segfaults. Bug869: Continued to look at ABS_EXPR cases (2/10). * Emails, meetings.

Hi, I have being trying to persuade gcc to generate the ldp instruction without success. I have tried many combinations, below is an example. --- cut here --- #define LDP(x,y,p) { \ struct vec { long x, y; } data; \ data = *(struct vec *)p; p += 2; \ x = data.x; y = data.y; \ } long testp(long *p) { long x, y; LDP(x, y, p); return x+y; } --- cut here --- $ gcc --version gcc (GCC) 4.9.1 Copyright (C) 2014 Free Software Foundation, Inc.

Discussed the same issue with sanitizer's group. They asked me to do -pie for aarch64 as first version. Pushed GCC changes to linaro git. TCWG-654 Discussed with Renato, moved to LLVM tree and woking on that. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64946. TCWG-634 Ran ASAN tests which 32 bit allocator code now as default on amd-01. /home/venkataramanan.kumar/LLVM/TSAN_port/Source/projects/compiler- rt/lib/sanitizer_common/sanitizer_allocator.h:841 ((res)) < ((kNumPossibleRegions)) (4193146, 524288) I got similar error in TSAN and it went off when I switched to 64 bit allocator. * Bug 869 - Wrote a pattern in match.pd to remove type promotion in ABS_EXPR . Richard Beiner suggested to add ABSU_EXPR to take care of signed overflows (3/10) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64946 * Emails, meetings.

RE: Debian Multiarch Tuple Style Naming With ABE

by Rob Savoye

Go away where ? ABE just uses whatever triplet you give it. I commonly use just arm-linux-gnueabi for example. If you don't specify 'none', it shouldn't appear anywhere. If it does, let me know and I'll fix it. - rob - -------- Original message -------- From: Christopher Covington <cov(a)codeaurora.org> Date: 02/26/2015 2:52 AM (GMT+07:00) To: linaro-toolchain(a)lists.linaro.org Subject: Debian Multiarch Tuple Style Naming With ABE Hi, I recently built with ABE for the first time. It's pretty slick. Is there a way to make the vendor string (the "none" in "arm-none-linux-gnueabihf-*") go away? It breaks my scripts without appearing to add value.

Problems porting Boost.Context to aarch64 gcc

by Edward Nevill

Hi, I am trying to port the Boost.Context library (from www.boost.org) to aarch64 gcc and have come across a gnarly problem. Boost.Context essentially does co-routine style context switching. It has a structure f_context which it uses to save and restore contexts. The structure f_context contains both integer (x0..xN) and floating point VFP (d8..d15) context. The function jump_context switches contexts typedef struct f_context *f_context_t extern void jump_context(fcontext_t *old, f_context_t new, bool save_fp); So this jumps to a new context returning the old context in *old. If save_fp is set the floating point context must be saved because the application uses floating point. Otherwise the save and restore of the floating point context may be ignored. So, essentially, to save the old context it does jump_fcontext: # prepare stack for GP + FPU sub sp, sp, #0xb0 # test if fpu env should be preserved cmp w3, #0 b.eq 1f # save d8 - d15 stp d8, d9, [sp, #0x00] stp d10, d11, [sp, #0x10] stp d12, d13, [sp, #0x20] stp d14, d15, [sp, #0x30] 1: # save x19-x30 stp x19, x20, [sp, #0x40] stp x21, x22, [sp, #0x50] stp x23, x24, [sp, #0x60] stp x25, x26, [sp, #0x70] stp x27, x28, [sp, #0x80] stp x29, x30, [sp, #0x90] However, there is a problem with this because gcc may store integer value in floating point registers around a function call. So, I have no way of knowing whether it is actually necessary to save/restore floating point context. Even worse applications using Boost.Context may be completely borken if they assume it is safe to call jump_context with save_fp == 0. Any suggestions? Ed.

Linaro GCC 4.9 2015.02 is the eleventh Linaro GCC source package release in the 4.9 series. It is based on FSF GCC 4.9.3-pre+svn220525 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. The Linaro TCWG provides stable[1] quarterly releases and monthly engineering[2] releases. Interesting changes in this GCC source package release include * Backport of [AArch32] PR63676, exit tree fold when node be TREE_CLOBBER_P * Backport of [AArch32] M0/M1 small multiply * Backport of [AArch64] Fix unsafe access to deallocated stack * Backport of Int div by constant compilation enhancement * Backport of [AArch32] Fix PR target/64460: Set 'shift' attr properly on some patterns * Backport of [AArch32] Fix typo in *<arith_shift_insn>_shiftsi * Backport of [AArch64] Let LR register allocable * Backport of Improve warning message for bitfields * Backport of [AArch32] PR rtl-optimization/64011 * Backport of Fix checking on MAX_PENDING_LIST_LENGTH * Backport of Remove VEC_LSHIFT_EXPR and vec_shl_optab * Backport of [AArch64] Use new reduc_[us](min|max)_scal optabs, inc. for builtins * Backport of [AArch64] Use new reduc_plus_scal optabs, inc. for __builtins * Backport of Add new optabs for reducing vectors to scalars * Backport of [Vectorizer] Make REDUC_xxx_EXPR tree codes produce a scalar result * Backport of [AArch32] new cortex-m7 tune option * Backport of [AArch32] cortex-m7 scheduling * Backport of Improve Neon intrinsics testing * Backport of [AArch32] [testsuite] gnu11 cleanup for aapcs testcases Linaro GCC 4.8 2015.02 is the sixteenth release in the 4.8 series and is in maintenance. Based off the latest GCC 4.8.4+svn220525 release, it includes performance improvements and bug fixes. The Linaro GCC 4.8 maintenance branch will be retired when Linaro GCC 5.1 is delivered. Linaro GCC 4.9 will become the new maintenance release. Interesting changes in this GCC source package release include: * Updates to GCC 4.8.4+svn220525 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?

14.11 Linaro Toolchain Release Questions

by Christopher Covington

Hi, We've noticed that in the 14.11 toolchain binary release that the .asc files contain md5sums instead of PGP signatures. Would it be possible to either switch these files to contain signatures or change the filename to indicate that they contain md5sums? I also noticed that an md5sum is missing: http://releases.linaro.org/14.11/components/toolchain/binaries/armeb-linux-… Finally, there appears to be some inconsistent usage of tuples in the download directories. Would it be possible to use the same tuple for a particular toolchain everywhere that tuple is used? For example, for the arm-none-eabi toolchain, the directory is "arm-none-eabi", but the compiler tarball has only "arm-eabi". Thanks, Chris -- Qualcomm Innovation Center, Inc.

QEMU Binaries & Overo Board Support

by Dominic Chen

Hello, I have a question about the status of overo support in qemu-linaro vs upstream qemu; from a quick look on the Git commits for qemu-linaro, most things seemed to have been ported back upstream into qemu as of v2.0.0, although there does appear to be some recent new commits. However, I'm looking for overo board support, and although I see that OMAP3 chip support has been merged upstream, there aren't any board configuration files for overo. What would be the easiest way to get working qemu overo board support? Additionally, I don't see any recent binary packages available for qemu-linaro. The qemu-linaro packages on the Ubuntu PPA haven't been built for almost a year now, and the releases.linaro.org page doesn't seem to have recent qemu-linaro builds either. Thanks, Dominic
