bugs with gollvm #16

Open advancedwebdeveloper opened 3 years ago

advancedwebdeveloper commented 3 years ago

Many packages do not build, using gollvm, if they depend on reflect2 package. So I am opening an issue, to track down bugs.

$ go version && go env go version go1.15rc2 gollvm LLVM 12.0.0git linux/amd64 GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/home/oceanfish81/.cache/go-build" GOENV="/home/oceanfish81/.config/go/env" GOEXE="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOINSECURE="" GOMODCACHE="/home/oceanfish81/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/home/oceanfish81/go" GOPRIVATE="" GOPROXY="https://proxy.golang.org,direct" GOROOT="/usr/local" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/tools" GCCGO="/usr/local/bin/llvm-goc" AR="ar" CC="/usr/bin/clang" CXX="/usr/bin/clang++" CGO_ENABLED="1" GOMOD="" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build330690378=/tmp/go-build -gno-record-gcc-switches -funwind-tables"
