Hi, As I reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78870#c16, the build of GCC for aarch64*-none-elf fails when configuring libstdc++ since r261034 (a week ago).
The root cause is PR66203 which I reported quite some time ago, which points to a newlib problem: on aarch64 there is no default rom monitor, one has to explicitly use a --specs flag for the link to succeed. Maybe I missed a change about this in newlib, and I should upgrade the version I use for GCC automatic validations? If not, and if there is not much interest in these configurations, maybe I should just drop them from my list? Alternatively, I could try to use LDFLAGS_FOR_TARGET=--specs=rdimon.specs in my validation scripts. Or, better, are there plans to fix this? I ask, because I have no immediate plans to look at this. Thanks, Christophe
