LLVM

昔の正式名称: Low Level Virtual Machine (現在は何の頭文字でもないらしい)

任意のプログラミング言語から任意のプロセッサのマシンコードにコンパイルできる基盤。

中間言語の最適化や様々なアーキテクチャへの対応がしやすく。

インストール

$ brew install llvm

code:txt

To use the bundled libc++ please add the following LDFLAGS:

LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"

llvm is keg-only, which means it was not symlinked into /usr/local,

because macOS already provides this software and installing another version in

parallel can cause all kinds of trouble.

If you need to have llvm first in your PATH, run:

echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> /Users/ishikwx/.bash_profile

For compilers to find llvm you may need to set:

export LDFLAGS="-L/usr/local/opt/llvm/lib"

export CPPFLAGS="-I/usr/local/opt/llvm/include"
