title: CbCによるMoarVMの改良 author: Takahiro Shimizu profile: lang: Japanese # 研究内容 - Perl5の後継言語として開発されているPerl6はMoarVMと呼ばれるVMを搭載している． - Perl6はMoarVM,JVM上で動くRakudoと呼ばれる実装と，コンパイラ開発者用のサブセットであるNQPが主な実装となっている． - 現在Perl6及びMoarVMは全体的な速度がPerl5と比較し低下しており，実務として利用できるレベルに達していない． - またPerl6の実装自体巨大なcase-switch文など見通しが悪くなっている． - 本研究では継続を中心に開発されたContinuation based Cを用いてMoarVMの改良を検討する． # 今週の進捗 - dalmoreでCbCgccでMoarVM/NQPが動きました # MoarVMのclone - MoarVMをgithubからcloneする ``` $ git clone https://github.com/MoarVM/MoarVM.git ``` # MoarVMのmake - Perlの`Configure.pl`を叩いてMakefileを生成する - 別のディレクトリからは叩け無い仕様に成っていた ``` ./Configure.pl --cc /usr/local/x86-cbc/bin/gcc --debug --compiler gcc --prefix=/mnt/dalmore-home/one/src/build_perl6/MoarVM` ``` - オプション - cc - コンパイラのパスを設定する - debug - debugオプション - compiler - コンパイラの種類を指定する - gcc, clang, clをサポートしている - toolchain - "posix", "gnu", "bsd" and "msvc"のツールチェインを選択可能 - prefix - make installの先を指定 # llvmでの実行 ``` (dalmore) ./Configure.pl --cc /usr/local/cbclang/bin/clang ``` - セグフォで死ぬ ``` 0.
