General notes: * GCC on Darwin depends on the installed “binutils”, typically provided by a version of “Xcode" or “Xcode command line tools”. Unless noted otherwise, the bootstrap sequences here make use of the last available xcode command line tools and SDK for the platform version.
* Two bootstrap and test sequences; 1) Using a version of GCC+Ada as the bootstrap compiler, allowing a build and test for Ada. 2) Using the Apple GCC or clang that relates to the installed command line tools. * In some cases, particularly with the earlier versions, the installed ‘atos’ is not really compatible with the versions of libsanitizer that are built with GCC8. In that case, it’s usually better to install a version of llvm-symbolizer and set the ASAN_SYMBOLIZER_PATH=/path/to/llvm-symbolizer. * I don’t have enough physical hardware to cover all of the versions directly, so some are (macOS hosted) VMs using VirtualBox. In these cases, timeouts are not necessarily significant (noted in the relevant results). cheers Iain --- Darwin19, (macOS 10.15) xcode 11.4b3 command line tools and SDK was current https://gcc.gnu.org/pipermail/gcc-testresults/2020-March/556866.html https://gcc.gnu.org/pipermail/gcc-testresults/2020-March/556867.html Darwin18 (10.14) https://gcc.gnu.org/pipermail/gcc-testresults/2020-March/556864.html https://gcc.gnu.org/pipermail/gcc-testresults/2020-March/556865.html Darwin17 (10.13) here I have used XC 9.4, to avoid the errors caused by the deprecation of m32 flagged by later tools.

It is possible to make the bootstrap with an updated ld64 with that limit fixed, and using -Os for the stage1 compiler options.
