libgcc: Move bitint support exports to x86/aarch64 specific map files
When adding _BitInt support I was hoping all or most of arches would
implement it already for GCC 14. That didn't happen and with
new hosts adding support for _BitInt for GCC 16 (s390x-linux and as was
posted today loongarch-linux too), we need the _BitInt support functions
exported on those arches at GCC_16.0.0 rather than GCC_14.0.0 which
shouldn't be changed anymore.
The following patch does that. Both arches were already exporting
some of the _BitInt related symbols in their specific map files, this
just moves the remaining ones there as well.
2025-05-20 Jakub Jelinek <ja...@redhat.com>
* libgcc-std.ver.in (GCC_14.0.0): Remove bitint related exports
from here.
* config/i386/libgcc-glibc.ver (GCC_14.0.0): Add them here.
* config/i386/libgcc-darwin.ver (GCC_14.0.0): Likewise.
* config/i386/libgcc-sol2.ver (GCC_14.0.0): Likewise.
* config/aarch64/libgcc-softfp.ver (GCC_14.0.0): Likewise.
