Hi gmp maintainers,
- update symbols for loongarch64.
gmp would fail to build from source on mips64r6el if we had bootstrapped
this port due to symbol issues. Methods for updating symbol files:
sed -i -e 's/!hppa/& !loongarch64/' libgmp10.symbols
- definition for mixed size 64 bit arithmetic.
I have added patch for loongarch64. The patch:
gmp-6.2.1-add-loongarch64-definition.patch
Please update the symbol file and consider applying the attached patch.
thanks,
Dandan Zhang
