[ANNOUNCE] Linaro GCC 6 and 7 2017.10 source snapshots
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2017.10 snapshot of Linaro GCC 6 and 7 source packages. o The GCC 7 series introduced an ABI change for ARM targets by fixing a bug (present since GCC 5, see link below) that affects conformance to the procedure call standard (AAPCS). 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. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected by this ABI change. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 For an explanation of the changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html o Linaro GCC 7 monthly snapshot[1] is based on FSF GCC 7.2+svn253626 and includes performance improvements and bug fixes backported from mainline GCC.

* Include GCC fix for Linaro bugzilla #2575:

__attribute__((target("thumb"))) and inlined assembler, with debug
symbols enabled
https://bugs.linaro.org/show_bug.cgi?id=2575
* Include GCC fix for Linaro bugzilla #2575:
Internal compiler error using -mtune=cortex-a57.cortex-a53.
https://bugs.linaro.org/show_bug.cgi?id=2785
* The soft-float targeted toolchains have now been configured to
generate code using -mfloat-abi=soft.
This makes arm-linux-gnueabi and armeb-linux-gnueabi toolchains use
the “soft” FP ABI instead of “softfp”.
Historically, TCWG’s toolchains provided both “soft” and “softfp”
multilibs, but when switching from crosstool-ng to cbuildv2/abe (which
support a single multilib) “softfp” multilib was choosen. Using
“-mfloat-abi=soft” is a better choice for a gnueabi toolchain, since
it doesn’t require cores to have a floating-point unit.
This change should not break compatibility for toolchain users since
the ABI will stay the same. The compiler and glibc libraries will not
refernce FP instructions.
* Include GCC fix for Linaro bugzilla #2562:
ARM GCC 5.2 call weak function instead of strong when called through
pointer

This was exhibited in Perf Tools build system and has been fixed upstream and backported into Linaro Binutils 2.27 branch.

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

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.

Binary releases no longer include runtest at all, and gdbserver is a target tool; it is now shipped in the sysroot under usr/bin/. LDTS case #2211: gdbserver and runtest in GCC binary release are in the wrong place or have the wrong name * Gdbserver is no longer linked statically, because this is currently unsupported. Linaro bugzilla #3344: gdbserver broken in Linaro 2017.02 https://bugs.linaro.org/show_bug.cgi?id=3344 * Previous MinGW hosted version of Linaro GCC C preprocessor failed to convert character set used for string, character constants, etc. This is fixed in 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 8.1 to 8.2. * 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
[ANNOUNCE] Linaro GCC 7.4 2019.01 source snapshot
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2019.01 snapshot of the Linaro GCC 7 source package. The GCC 7 series introduced an ABI change for ARM targets by fixing a bug (present since GCC 5, see link below) that affects conformance to the procedure call standard (AAPCS). 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. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected by this ABI change. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 For an explanation of the changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html This snapshot1 is based on FSF GCC 7.4+svn267072 and includes performance improvements and bug fixes backported from mainline GCC. The contents of this snapshot will be part of the 2019.01 stable2 periodic release.

[ANNOUNCE] Linaro Binary Toolchain Release GCC 7.4-2019.02
The Linaro Binary Toolchain The Linaro GCC 7.4-2019.02 Release 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.

See the following for the life-time of Ubuntu LTS releases. https://wiki.ubuntu.com/Releases The host system upon which the cross-compiler will run requires a minimum of glibc 2.14, because of API changes to glibc's memcpy API. https://bugs.linaro.org/show_bug.cgi?id=1869 Package Versions = Linaro GCC 7.4-2019.02 http://releases.linaro.org/components/toolchain/gcc-linaro/7.4-2019.02/ FSF glibc 2.25 (release/2.25) https://lists.gnu.org/archive/html/info-gnu/2017-02/msg2.html Newlib 2.5 (newlib-2_5_0 tag) https://sourceware.org/ml/newlib/2016/msg01191.html GNU Binutils 2.28 (users/linaro/binutils-2_28-branch) https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=binutils/NEWS;hb=refs/tags/binutils-2_28 FSF GDB 8.2 (gdb-8.2-branch) https://lists.gnu.org/archive/html/info-gnu/2018-09/msg1.html Linaro toolchain package git branches are hosted at: http://git.linaro.org/toolchain NEWS for GCC 7 (as of Linaro GCC 7.4-2019.02) == * Runtest and gdbserver are no longer installed in the toolchain bin/ directory. Binary releases no longer include runtest at all, and gdbserver is a target tool; it is now shipped in the sysroot under usr/bin/. LDTS case #2211: gdbserver and runtest in GCC binary release are in the wrong place or have the wrong name * Gdbserver is no longer linked statically, because this is currently unsupported. Linaro bugzilla #3344: gdbserver broken in Linaro 2017.02 https://bugs.linaro.org/show_bug.cgi?id=3344 * The Linaro GCC 7.4-2019.01 snapshot added a fix for Linaro bug 4007: "Internal compiler error with -mcpu=thunderx2t99". * The Linaro GCC 7.2-2017.09 snapshot added float and integer moves improvement for AArch64 targets. * The Linaro GCC 7.1-2017.07 snapshot added prefetching configuration improvement for AArch64 targets and laid groundwork to enabling prefetching in more cases. * Previous MinGW hosted version of Linaro GCC C preprocessor failed to convert character set used for string, character constants, etc. This is fixed in this release. Linaro bugzilla #3040 : CC1 and cc1plus cannot convert UTF-8. https://bugs.linaro.org/show_bug.cgi?id=3040 * Performance related backports from the following snapshots have been included: Linaro GCC 7.1-2017.05, Linaro GCC 7.1-2017.06, Linaro GCC 7.1-2017.07, Linaro GCC 7.2-2017.08, Linaro GCC 7.2-2017.09, Linaro GCC 7.2-2017.10, Linaro GCC 7.2-2018.04 and Linaro
