Thanks for the review, Lucas. I added the proper "LP: #" snippet to the d/changelog entry, and uploaded the package now:

Upstream has fixed this by removing support for Cyclades from libsanitizer: https://github.com/llvm/llvm- project/commit/884040db086936107ec81656aa5b4c607235fb9a As for the GCC 11 failure, the problem is: [ 19%] Building CXX object tools/clang/utils/TableGen/CMakeFiles/obj.clang-tblgen.dir/ClangDiagnosticsEmitter.cpp.o cd /<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/utils/TableGen && /<<PKGBUILDDIR>>/build-llvm/./bin/clang++ -DCLANG_VENDOR="\"Ubuntu \"" -D_GNU_SOURCE -D__STDC_CONSTANT_M ACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -I/<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/utils/TableGen -I/<<PKGBUILDDIR>>/clang/utils/TableGen -I/<<PKGBUILDDIR> >/clang/include -I/<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/tools/clang/include -I/<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/include -I/<<PKGBUILDDIR>>/llvm/include -fuse -ld=gold -fPIC -Wno-unused-command-line-argument -Wno-unknown-warning-option -fPIC -fvisibility-inlines-hidden -Werror=date-time -Werror=unguarded-availability-new -Wall -Wextra -Wno-unused -parameter -Wwrite-strings -Wcast-qual -Wmissing-field-initializers -pedantic -Wno-long-long -Wimplicit-fallthrough -Wcovered-switch-default -Wno-class-memaccess -Wno-noexcept-type -Wnon-vi rtual-dtor -Wdelete-non-virtual-dtor -Wstring-conversion -ffunction-sections -fdata-sections -fno-common -Woverloaded-virtual -Wno-nested-anon-types -O2 -DNDEBUG -g1 -fno-exceptions -std=c ++14 -o CMakeFiles/obj.clang-tblgen.dir/ClangDiagnosticsEmitter.cpp.o -c /<<PKGBUILDDIR>>/clang/utils/TableGen/ClangDiagnosticsEmitter.cpp In file included from /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.cc:15: /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:30: error: no member named 'numeric_limits' in namespace 'std' static const T kmax = std::numeric_limits<T>::max(); ~~~~~^ /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:45: error: 'T' does not refer to a value static const T kmax = std::numeric_limits<T>::max(); ^ /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:8:20: note: declared here template <typename T> ^ /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:47: error: no member named 'max' in the global namespace; did you mean 'kmax'? static const T kmax = std::numeric_limits<T>::max(); ^~~~~ kmax /<<PKGBUILDDIR>>/llvm/utils/benchmark/src/benchmark_register.h:17:18: note: 'kmax' declared here static const T kmax = std::numeric_limits<T>::max(); This comes from the fact that GCC 11 requires the inclusion of the <limits> header in order to access std::numeric_limits<T>. This has also been fixed upstream: https://github.com/llvm/llvm- project/commit/b498303066a63a203d24f739b2d2e0e56dca70d1 I'm preparing and testing a patch, and will attach it to this bug soon.
