  Features:

  • All GCC 10.3 features.

  Known issues:

  • Doing IPA on CMSE generates a linker error: The linker will error out when resulting object file contains a symbol for the clone function with the __acle_se prefix that has a non-local binding. Issue occurs when compiling binaries for M-profile Secure Extensions where the compiler may decide to clone a function with the cmse_nonsecure_entry attribute. Although cloning nonsecure entry functions is legal, as long as the clone is only used inside the secure application, the clone function itself should not be seen as a secure entry point and so it should not have the __acle_se prefix. A possible workaround for this is to add a 'noclone' attribute to functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning such functions.
  • GCC can hang or crash if the input source code uses MVE Intrinsics polymorphic variants in a nested form. The depth of nesting that triggers this issue might vary depending on the host machine. This behaviour is observed when nesting 7 times or more on a high-end workstation. On less powerful machines, this behaviour might be observed with fewer levels of nesting. This issue is reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91937

    and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99939
    where CMSE support was missing from multilibs.

    where the correct multilibs were not linked when using the
    Custom Datapath Extension (+cdecp[0-7]) with the -march option.

    offsets in Thumb code.

    * Fixed issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99960
    where V2DImode loads and stores for MVE might be miscompiled.

    * Fixed issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99725

    * Fixed issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99271

    Notable changes in 2020-q4-major release:
    * Added support for:
    + M-profile Vector Extension (MVE) assembler and intrinsics
    + Custom Datapath Extension (CDE)
    + Cortex-M55

    * Fixed issue where load or store of __fp16 type together with MVE
    might generate invalid code.

    * Fixed issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91816
    where the compiler was generating a conditional branch in Thumb2,
    which was too far for b{cond} to handle.

    * Fixed internal errors in arm and aarch64 GAS when assembling code
    that attempts a negative .org.

    * Fixed issue https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96191
    where the -fstack-protector option was leaving the canary value
    in a temporary register on return from the function.

    Known issues:
    * Doing IPA on CMSE generates a linker error:
    The linker will error out when resulting object file contains a symbol for
    the clone function with the __acle_se prefix that has a non-local binding.
    Issue occurs when compiling binaries for M-profile Secure Extensions where
    the compiler may decide to clone a function with the cmse_nonsecure_entry
    attribute.
    Although cloning nonsecure entry functions is legal, as long as the clone
    is only used inside the secure application, the clone function itself should
    not be seen as a secure entry point and so it should not have the __acle_se
    prefix.
    A possible workaround for this is to add a 'noclone' attribute to
    functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning
    such functions.
    * GCC can hang or crash if the input source code uses MVE Intrinsics polymorphic variants in a nested form.The depth of nesting that triggers this issue might vary depending on the host machine.This behaviour is observed when nesting 7 times or more on a high-end workstation.On less powerful machines, this behaviour might be observed with fewer levels of nesting.This issue is reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91937

  Features:

  • All GCC 10.1 features.

  Known Changes and Issues:

  • Doing IPA on CMSE generates a linker error:
    The linker will error out when resulting object file contains a symbol for the clone function with the __acle_se prefix that has a non-local binding. Issue occurs when compiling binaries for M-profile Secure Extensions where the compiler may decide to clone a function with the cmse_nonsecure_entry attribute. Although cloning nonsecure entry functions is legal, as long as the clone is only used inside the secure application, the clone function itself should not be seen as a secure entry point and so it should not have the __acle_se prefix. A possible workaround for this is to add a 'noclone' attribute to functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning such functions.
  • Load or Store of __fp16 type together with MVE might generate invalid code:
    If you use __fp16 type together with MVE enabled, then when the compiler needs to generate an instruction to load a Floating-point Extension register (S register) from memory or an instruction to store a Floating-point Extension register (S register) to memory, then the compiler generates the wrong assembly instruction. The wrong assembly instruction is generated by the front-end for any optimization other than -O0. The wrong instruction causes an error during assembly, for example:
    "Error: instruction does not support writeback - `vstr.16 s15,[r0]!'"
    "Error: instruction does not support writeback - `vldr.16 s15,[r0]!'"
    The workaround is to use the -O0 command line option to generate the correct instruction when loading or storing of __fp16 type together with MVE.
  • Uncompressing the Windows zip file requests permission to overwrite file:
    When you decompress the windows zip file, gcc-arm-none-eabi-10-2020-q2-preview-win32.zip, the decompression requests permission to overwrite the file frame-apply.html. This is because the GDB documentation within the folder share/doc/gcc-arm-none-eabi/html/gdb contains files that are named frame-apply.html and Frame-Apply.html, which are treated as identical names on a Windows host.
    You can choose to overwrite the file frame-apply.html with Frame-Apply.html. If you decompress the zip file using a command-line tool, you can use a command-line option to automatically overwrite the file, for example by using the -y command-line option with 7zip.

    The linker will error out when resulting object file contains a symbol for the clone function with the __acle_se prefix that has a non-local binding. Issue occurs when compiling binaries for M-profile Secure Extensions where the compiler may decide to clone a function with the cmse_nonsecure_entry attribute. Although cloning nonsecure entry functions is legal, as long as the clone is only used inside the secure application, the clone function itself should not be seen as a secure entry point and so it should not have the __acle_se prefix. A possible work around for this is to add a 'noclone' attribute to functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning such functions.

    Known issues:
    * Doing IPA on CMSE generates a linker error:
    The linker will error out when resulting object file contains a symbol for
    the clone function with the __acle_se prefix that has a non-local binding.
    Issue occurs when compiling binaries for M-profile Secure Extensions where
    the compiler may decide to clone a function with the cmse_nonsecure_entry
    attribute.
    Although cloning nonsecure entry functions is legal, as long as the clone
    is only used inside the secure application, the clone function itself should
    not be seen as a secure entry point and so it should not have the __acle_se
    prefix.
    A possible work around for this is to add a 'noclone' attribute to
    functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning
    such functions.

    Important bugs fixed in 5 update 2 release:
    * Fixed code-size regression for Cortex-M0 compared to 4.9 when compiling with -Os
    * Fix multilib used for armv8-m.main+dsp
    * Fix use of --gc-sections when building for Armv8-M with Security Extensions
    * Fix memcpy used for newlib-nano for pre Armv6T2 devices

    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59535
    A workaround is to disable it by option -mno-lra.
    * The use of 64-bit atomic operations for Armv8-M Mainline is not supported.
