一、gollvm可以构建成功的commits：
gollvm commit: 0e34e09fc15cde73f1b9974f2a657360abb94b4f libbacktrace commit: 2446c66076480ce07a6bd868badcbceb3eeecc2e libffi commit: ab1677106605aba1c27665964ff90bea59612ce3 gofrontend commit 7f33baa09a8172bb2c5f1ca0435d9efe3e194c9b llvm-project commit 09629215c272f09e3ebde6cc7eac9625d28910ff
参考链接：https://groups.google.com/g/golang-nuts/c/sTh5tpz7ork/m/yQWQTX1zAAAJ
需要执行以下命令获取对应的commit快照代码
git checkout commit-ID
二、针对MacOS，需要确保SHELL环境变量指向 /usr/bin/bash
参考：golang/go#36554
否则会有类似错误
/Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:162: no such file or directory: callee.go imports.go map.go methodsetcache.go ui.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:172: no such file or directory: callee.go imports.go map.go methodsetcache.go ui.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:162: no such file or directory: analysis.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:172: no such file or directory: analysis.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:162: no such file or directory: input.go matcher.go symbol.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:172: no such file or directory: input.go matcher.go symbol.go /Users/daniel/llvmProjects/llvm-project/llvm/tools/gollvm/gofrontend/libgo/match.sh:162: no such file or directory: common.go enabled_go117.go enabled_go118.go normalize.go termlist.go typeparams_go117.go typeparams_go118.go typeterm.go
三、MACOS的目标系统市x86，不是x86_64
cmake中增加-DLLVM_TARGETS_TO_BUILD=X86
四、macos上编译LLVM mkdir build-llvm cd build-llvm cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_ENABLE_CXX1Y=ON -DLLVM_ENABLE_ASSERTIONS=ON -DSPHINX_OUTPUT_HTML=OFF -DSPHINX_OUTPUT_MAN=OFF ../llvm-project/llvm cmake --build
