(I haven't run build-many-glibcs.py with -Os lately, so it's possible more problems have crept in or appear with current compilers. When I was testing it, it failed for m68k - the m68k libm functions don't build with -Os because bits/mathinline.h doesn't get included then, which needs addressing anyway in some way to eliminate bits/mathinline.h from glibc - but worked for most or all other configurations.) > (d) We currently only support soft float ABI, although I'm working on hard float > and hopefully will have it ready sometime during the review of this series Could you confirm what the ABI entry or entries to go at <https://sourceware.org/glibc/wiki/ABIList> would look like? Note that we generally expect new ports to use different dynamic linker names for each ABI. This means separate names for hard float and soft float. Since it appears you support both big and little endian, it also means separate dynamic linker names for each of those (and corresponding GCC changes will be needed to pass the right dynamic linker names to ld's -dynamic-linker option). Then, each supported ABI should have a build in build-many-glibcs.py, and any unsupported ABI variants need to have a configure-time error (to avoid accidentally building a glibc incompatible with the correct ABI for such a port added in future). -- Joseph S.
