Hi,
I want to rebuild the newest GCC 11.2 toolchain for my project as I want to introduce some space optimization flags.
On the GCC 10.3 release the process was pretty straightforward as the source code included the build-toolchain.sh script.
On the 11.2 release I didn't find such script anymore. There is a linaro abe manifest on https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/manifest/gcc-arm-arm-none-eabi-abe-manifest.txt, which also differs from the incomplete 11.2-2022.02-x86_64-arm-none-eabi-manifest.txt file included in the toolchain tar from https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi.tar.xz
Could you give me some pointers on how to reproduce the release build so I can add the appropriate flags?
Thanks in advance!
The instructions for building the toolchain from source is given in the Release Note, which is linked from:
https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/downloads
In the Release Note, there is a section on "How to build the toolchain from sources".
Do you know how to build newlib nano with Linaro ABE build system ?
With the example gcc-arm-arm-none-eabi-abe-manifest.tx it only builds newlib.
I added:
# Component data for newlib-nano newlib_nano_url=https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/src newlib_nano_filespec=newlib-cygwin.tar.xz newlib_nano_mingw_only="no" newlib_nano_linuxhost_only="no" newlib_nano_staticlink="yes" newlib_nano_configure="--disable-newlib-supplied-syscalls --enable-newlib-nano-malloc --disable-newlib-unbuf-stream-opt --enable-newlib-reent-small --disable-newlib-fseek-optimization --enable-newlib-nano-formatted-io --disable-newlib-fvwrite-in-streamio --disable-newlib-wide-orient --enable-lite-exit --enable-newlib-global-atexit --enable-newlib-reent-check-verify"
but I think it overwrites the results from newlib built. I checked how Arch Linux package is build and they rename it:

Any Idea or pointer where it is described ?
