Hello! This is a second version for the patch for 32-bit, against MASTER branch.
@Martin, I tested all the new tunes with your script, and I got no errors. About 64-bit tunes, I need some guidance about the approach for adding specific tunes for aarch64. I tried to inherit the ones from 32-bit and to add the aarch64 feature, but I got those errors when building libgcc-initial: | aarch64_be-oe-linux-gcc: error: unrecognized command line option '-mfpu=crypto-neon-fp-armv8' | aarch64_be-oe-linux-gcc: error: unrecognized command line option '-marm' | aarch64_be-oe-linux-gcc: error: unrecognized command line option '-mfpu=neon' | aarch64_be-oe-linux-gcc: error: unrecognized command line option '-mfloat-abi=hard' I searched and I found that aarch64 didn't support thumb or neon options: https://gcc.gnu.org/onlinedocs/gcc/AArch64-Options.html It seems that AArch64 and ARM backends are completely separate in gcc. For aarch64 I found just those options: ‘crc’ Enable CRC extension. This is on by default for -march=armv8.1-a. ‘crypto’ Enable Crypto extension. This also enables Advanced SIMD and floating-point instructions. ‘fp’ Enable floating-point instructions. This is on by default for all possible values for options -march and -mcpu. ‘simd’ Enable Advanced SIMD instructions. This also enables floating-point instructions. This is on by default for all possible values for options -march and -mcpu. ‘lse’ Enable Large System Extension instructions. This is on by default for -march=armv8.1-a. Any help will be highly appreciated!
