Aarch64 Toolchain - aarch64-elf-gcc.exe: error: CreateProcess: No such file or directory

by Glen Verran

Hi there I need to cross-compile an application written in C for ARM v8 (aarch64) and found the toolchain on your website. I am running Windows 10 using Cygwin 32-bit as I am already compiling for arm6, arm7 and Linux (x86 and x64) successfully. I downloaded https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-el… and deployed it into my Cygwin installation with no issues. When I ran my script, I get the following error message: aarch64-elf-gcc.exe: error: CreateProcess: No such file or directory I enabled verbose mode on the GCC and the result is below. My Cygwin's default GCC version is 4.8.3, but I am running 7.2.1 for this. I also tried 4.9.4 as well using a different Cygwin instance. Can you please advise how I can get around this error? I am able to cross-compile using the 100% exact script with all other architectures with the only difference being the toolchain and architecture. Cygwin DLL version (just in case). I called: cygcheck -p cygwin1.dll |grep "cygwin:" And it returned: cygwin-2.10.0-1 - cygwin: The UNIX emulation engine cygwin-2.8.2-1 - cygwin: The UNIX emulation engine cygwin-2.9.0-3 - cygwin: The UNIX emulation engine 7.2.1 Using built-in specs.

[ACTIVITY] - Landed D44928, we should pass the subtarget through to fixups and relaxation now. The only remaining use of the subtarget in the assembler backend is for writeNop(). Patches to fix that are upstream but I'm not hopeful that anyone will want to review them due to the cost/benefit. - Wrote up some thoughts on Maxim's idea to use pgo to optimize hot code for time, but cold code for size in an attempt to retain as much as performance as possible while reducing code-size. - Some investigation into the --pgo option of lnt. There seem to be some pre-requisites and some interactions that have made it difficult to get results: -- Needs compiler-rt, duh! But it didn't tell me until after I'd waited for everything to compile. -- Failed when I enabled perf and pgo, looks to be a configuration problem where profile-generate and profile-use are set simultaneously. Probably a cmake problem. - Some work on side-project to implement the tiny code model -- Have something working on small examples, much more testing needed. -- Need to decide what to do about TLS.

Turns out that upstream have a proposal that is much further along so shifted focus on to doing as much as I can to help it along. Found out that for some use cases of AArch64 PIC the small code model is inappropriate as the code segments may not be 4k aligned. Started looking into what it would take to implement the tiny code model in LLVM (supports only small and large at the moment). Built a small prototype to handle the easiest absolute addressing case, much more work needed to handle PIC and TLS. Not a lot of tangible progress, but I think I have learned a bit more about LLVM. Planned Absences - Friday 25th May (holiday). - Monday 28th May (UK public holiday)

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 7.3-2018.05-rc1

by Mark Murray

The Linaro Binary Toolchain ============================ The Linaro GCC 7.3-2018.05-rc1 Release-Candidate is now available. *Notice*: GCC 7.1 ABI change for arm*-*-* targets, and note for aarch64*-*-* targets From GCC 7.1 release notes: On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects conformance to the procedure call standard (AAPCS) has been fixed. The bug affects some C++ code where class objects are passed by value to functions and could result in incorrect or inconsistent code being generated. This is an ABI change. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 GCC 5 and GCC 6 releases will continue to be affected by the ABI bug, since changing ABI in these releases is not practical. A warning enabled by -Wpsabi option was added to GCC 5 and GCC 6 toolchains to diagnose codebases that might be affected by the ABI bug. Additionally, this same bug was present in AArch64 backend in development versions of GCC 7. There was no releases of GCC with this bug present in AArch64 backend, therefore the release notes does not mention this. However, be advised that any code bases built with development versions of GCC 7 need to be recompiled with released version of GCC 7 to conform to ABI. For an explanation of GCC 7 series changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html For help in porting to GCC 7 please see the following explanation: https://gcc.gnu.org/gcc-7/porting_to.html Download release-candidate packages from: (sources) http://snapshots.linaro.org/components/toolchain/gcc-linaro/7.3-2018.05-rc1/ (binaries) http://snapshots.linaro.org/components/toolchain/binaries/7.3-2018.05-rc1/ Previous snapshots and release-candidates are at: http://snapshots.linaro.org/components/toolchain/binaries/ Previous releases are at: http://releases.linaro.org/components/toolchain/binaries/ A description of the arm and AArch64 target triples can be found at: https://collaborate.linaro.org/display/TCWGPUB/ARM+and+AArch64+Target+Tripl… Host Requirements ================== Linaro officially supports the current and previous Ubuntu LTS releases (as of the time of this release).

Linaro bugzilla #3040 : CC1 and cc1plus cannot convert UTF-8. https://bugs.linaro.org/show_bug.cgi?id=3040 * The Linaro GCC 6.3-2017.05 snapshot added support for -mpure-code option to ARMv7-M and ARMv8-M targets. This option ensures functions are put into sections that contain only code and no data. * The GDB version was upgraded from GDB 8.0 to 8.1. * Previous versions of the Linaro GCC 6 toolchain, when -static -E/—dynamic-list are passed to the linker, might create executables with dynamic sections which aren’t supported by run-time. This was exhibited in Perf Tools build system and has been fixed upstream and backported into Linaro Binutils 2.27 branch. Linaro bugzilla #2926 : Perf tools compiled statically for AArch64 with Linaro release 6.1 and later ones was not statically linked. https://bugs.linaro.org/show_bug.cgi?id=2926 * The Linaro GCC 6.3-2017.03 snapshot fixed some ILP32 issues (TLS, exception handling, …) and these have been incorporated into this release. * Previous versions of the Linaro GCC 6 toolchain were incorrectly generating floating-point code for soft-float Linux targets (arm-linux-gnueabi, and armeb-linux-gnueabi). This escaped detection until recently because the soft-float targeted toolchains were configured to use general-purpose registers for passing floating-point values (which is what you would expect for soft-float toolchains) and the intra-routine floating-code was not noticed. The issue would only show up on targets that were run on hardware that truly didn't have floating-point hardware where the kernel did not trap and emulate floating-point routines. This has been solved in Linaro GCC 6.3-2017.02-rc2 by configuring the toolchain (using --with-float=soft) to generate code without any floating-point instructions at all (-mfloat-abi=soft). https://review.linaro.org/#/c/16968/2 This change should not break compatibility between existing binaries compiled with these toolchains since the float-point parameter passing ABI is still the same. * A bug/regression in the compiler has been identified whereby the target function that is invoked when calling a "weak" function directly is the "strong" override, whereas when calling the function via a pointer the "weak" implementation is used. This would be noticed as inconsistent function invocation when invoking directly vs. invoking via function pointer. This issue only affected 32-bit arm targets. This regression has been fixed upstream and backported into Linaro GCC 6.3-2017.02-rc2. GCC PR target/78253: [5/6/7 Regression] [ARM] call weak function instead of strong when called through pointer. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78253 Linaro bugzilla #2562: ARM GCC 5.2 call weak function instead of strong when called through pointer https://bugs.linaro.org/show_bug.cgi?id=2562 * MS Windows does not support symlinks and the MS Windows archive extractor does not properly deep copy the symlink target files/directories into the symlinked directory structure when unpacking the toolchain archive. This causes problems with missing dependencies when using the Linaro mingw toolchains, as identified in the following bugs: https://bugs.linaro.org/show_bug.cgi?id=2684 https://bugs.linaro.org/show_bug.cgi?id=2192 https://bugs.linaro.org/show_bug.cgi?id=2762 This has been solved by copying files rather than using symlinks when the mingw targetted toolchain archives are created. https://review.linaro.org/#/c/16415/ * Users of Linaro's toolchain have encountered problems when building projects with Autotools (specifically libtool): https://bugs.linaro.org/show_bug.cgi?id=2764 The Linaro binary toolchain release contained files with a .la suffix as artifacts of the toolchain build process. These .la files are helper files for libtool, but unlike a gcc install tree, they are not position independent and contain full paths. Since these artifacts contain absolute paths they can actually mislead user invocation of libtool into not finding required libraries (because they reference the build tree, not the install location) and hence breaking Autotools builds. These *.la file artifacts have been removed from Linaro toolchain binaries because they are unnecessary for users. * The Linaro GCC 6.3-2017.01 snapshot added further enablement for ARMv8-M and these have been incorporated into this release. * Compiling and statically linking some SPEC2006int tests against tcmalloc have been failing due to a problem with glibc's memory allocator function overrides. This was fixed upstream: https://sourceware.org/bugzilla/show_bug.cgi?id=20432 Backported into Linaro glibc 2.23: commit 058b5a41d56b9a8860dede14d97dd443792d064b Author: Florian Weimer <fweimer(a)redhat.com> Date: Fri Aug 26 22:40:27 2016 +0200 malloc: Simplify static malloc interposition [BZ #20432] * Host binaries for x86_64 linux hosts now have symbols and debug information stripped in order to reduce the size of the toolchain binary archives. This reduces the archive size from 1.5G to 600M for aarch64-linux-gnu target with the gcc-6-branch. * The GDB version was upgraded from GDB 7.11 in the Linaro GCC 6.1-2016.08 release to GDB 7.12 in the Linaro GCC 6.2-2016.11 release. * The Linaro GCC 6.2-2016.10 snapshot added AArch32 support for ARMv8.2 and ARMv8m, as well as some AArch64 fixes for ARMv8.2, and bug fixes merged from FSF GCC 6.2. This is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * Basic tuning support for the Qualcomm qdf24xx was added to the Linaro GCC 6.2-2016.10 snapshot and is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * IFUNC was disabled for baremetal targets, as it was causing test-suite failures, and is presently a Linux only feature. * The gold linker was added to this binary release. * Backported malloc_lock fix into Linaro newlib 2.4. commit 2665915cfc46aa6403bb2efd473c523d3167e0cb Author: Andre Vieira (lists) <Andre.SimoesDiasVieira(a)arm.com> Date: Thu Jun 16 12:23:51 2016 +0100 Re-enable malloc_lock for newlib-nano * Backported rawmemchr patch into Linaro newlib 2.4. commit e7b1ee2ea6aa3ee1da41976407410e6202a098c5 Author: Wilco Dijkstra <Wilco.Dijkstra(a)arm.com> Date: Thu May 12 16:16:58 2016 +0000 Add rawmemchr * Backported strlen fix when using Thumb-2 and -Os -marm into Linaro newlib 2.4. commit 5c02bcc086a96b174e1b9e1445a4a1770070107a Author: Thomas Preud'homme <thomas.preudhomme(a)arm.com> Date: Wed May 11 17:18:48 2016 -0400 Fix strlen using Thumb-2 with -Os -marm * Backported fix for semihosting ARM when heapinfo not provided by debugger into Linaro newlib 2.4. commit 5c9403eaf40951f8a4f55ed65f661b485ff44be7 Author: David Hoover <spm2(a)dangerous.li> Date: Thu Apr 21 07:12:24 2016 +0200 Fixed semihosting for ARM when heapinfo not provided by debugger. * Merged latest FSF glibc release/2.23/master into Linaro glibc 2.23. * Backported __ASSUME_REQUEUE_PI check Linaro glibc 2.23 branch. commit 2d20c3bf918cd94ebd4106693adb3a5c9272baba Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Tue May 17 10:16:39 2016 -0300 Add runtime check for __ASSUME_REQUEUE_PI (BZ# 18463) * Backported removal of __ASSUME_SET_ROBUST_LIST from Linaro glibc 2.23 branch. commit bb8f09d72756186a3d82a1f7b2adcf8bc1fbaed1 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 19:01:10 2016 -0300 Remove __ASSUME_SET_ROBUST_LIST * Backported removal of __ASSUME_FUTEX_LOCK_PI from Linaro glibc 2.23 branch. commit e48b4e7fed0de06dd7832ead48bea8ebc813a204 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 10:35:25 2016 -0300 Remove __ASSUME_FUTEX_LOCK_PI * Merged latest FSF binutils-2_27-branch into linaro_binutils-2_27-branch. * The libwinpthread DLL is now copied into the host bin directory to satisfy mingw package dependencies. * Backported GNU Linker fix. commit fbc6c6763e70cb2376e2de990c7fc54c0ee44a59 Author: Nick Clifton <nickc(a)redhat.com> Date: Tue Aug 23 09:45:11 2016 +0100 Fix seg-fault in ARM linker when trying to parse a binary file. * Backported GNU Assembler fix for PR 20364 commit 5fe7ebe5ab43750abf8f490b785d99a1e598e7fd Author: Nick Clifton <nickc(a)redhat.com> Date: Fri Aug 5 10:37:57 2016 +0100 Fix the generation of alignment frags in code sections for AArch64. https://sourceware.org/bugzilla/show_bug.cgi?id=20364 * Performance related backports from the following snapshots have been included: Linaro GCC 6.1-2016.06, Linaro GCC 6.1-2016.07, Linaro GCC 6.1-2016.08, Linaro GCC 6.2-2016.09, Linaro GCC 6.2-2016.10, Linaro GCC 6.2-2016.11, Linaro GCC 6.2-2016.12, Linaro GCC 6.3-2017.01, Linaro GCC 6.3-2017.02, Linaro GCC 6.3-2017.03, Linaro GCC 6.3-2017.04, Linaro GCC 6.3-2017.05, Linaro GCC 6.3-2017.06, Linaro GCC 6.4-2017.07, Linaro GCC 6.4-2017.08, Linaro GCC 6.4-2017.09, Linaro GCC 6.4-2017.10 and Linaro GCC 6.4-2018.04.
