Successful builds have been made on i686-darwin{9,10), powerpc-darwin9 x86_64-darwin{10,11,12,13,14,15,16,17,18} bootstrapped with GCC (including Ada)
test results are from https://gcc.gnu.org/ml/gcc-testresults/2019-08/msg01662.html to https://gcc.gnu.org/ml/gcc-testresults/2019-08/msg01673.html and x86_64-darwin18 bootstrapped with clang (no Ada test results: https://gcc.gnu.org/ml/gcc-testresults/2019-08/msg01674.html NOTES 1. *-darwin8 is currently not working with any live branch or trunk there’s a hope to address this before 9.3 2. anything earlier than darwin8 is going to require considerable work to build current branches, since the native installed tools do not meet the minimum requirements for GCC build. 3. some of the build/tests were performed on VMs; these are noted, and test timeouts should be regarded as “not significant” there.
