你可能已经听说过PGO（Profile-Guided Optimization）和LTO（Link Time Optimization）。那么，我们究竟应该如何理解这两种优化技术呢？本文将深入探讨PGO和LTO，展示它们的工作原理，如何在项目中实现，以及它们在实际应用中的优缺点。
对从CVS下载的版本默认值是"yes"(=assert,misc, tree,gc,rtlflag,runtime),对于正式发布的版本则是"release"(=assert,runtime)。可以从 "assert,fold,gc,misc,rtlflag,runtime,tree,gcac,rtl"中选择你想要检查的项目(逗号隔开的列表),需要注意的是最后两项检查非常耗时。使用 --disable-checking 完全禁止这种...
在"gcc"子目录下,对从CVS下载的版本默认值是"yes"(=assert,misc,tree,gc,rtlflag,runtime),对于正式发布的版本则是"release"(=assert,runtime),在"libgcc"子目录下,默认值始终是"no"。可以从 "assert,df,fold,gc,gcac,misc,rtlflag,rtl,runtime,tree,valgrind"中选择你想要检查的项目(逗号隔开的列表,"a...
Assert that compilation takes place in a hosted environment. This implies -fbuiltin. A hosted environment is one in which the entire standard library is available, and in which "main" has a return type of "int". Examples are nearly everything except a kernel. This is equivalent to -fno-...
众所周知，你不能把一个大的Assert集合，把它们变成假设（通过__builtin_unreachable），并期望好的结果...
