The Linaro Binary Toolchain
============================
The Linaro GCC 6.4-2018.05 Release is now available.
The GCC 6 Release series has significant changes from the GCC 5
release series. For an explanation of the changes please see the
following website:
https://gcc.gnu.org/gcc-6/changes.html
For help in porting to GCC 6 please see the following explanation:

Host Requirements
==================
Linaro officially supports the current and previous Ubuntu LTS
releases (as of the time of this release). This does not mean that
the toolchain will not work on other/older Linux distributions. 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.

NEWS for GCC 6 (as of Linaro GCC 6.4-2018.05)
==============================================
* 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
* 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 8.0 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 <***@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.
