    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

    • 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.
