youbest 的文章已是三年前有多,你却拿今天的手册对比,不大恰当吧
CLFS SVN 手册的注解比较多一点点:
http://cross-lfs.org/view/svn/x86_64/final-system/ppl.html
The Parma Polyhedra Library (PPL) provides numerical abstractions especially targeted at applications in the field of analysis and verification of complex systems. CLooG-PPL requires this library.
http://cross-lfs.org/view/svn/x86_64/final-system/cloog-ppl.html
CLooG-PPL is a library to generate code for scanning Z-polyhedra. In other words, it finds code that reaches each integral point of one or more parameterized polyhedra. GCC links with this library in order to enable the new loop generation code known as Graphite.
这是新版 Toolchain (gcc-4.4.x 後追加的),跟 youbest 的文章里所用的 Toolchain 不同
但这个玩意的真正用途我也不大清楚 :( |
