Gcc link-time optimization
WebMay 1, 2024 · Whole program optimization includes (practically, at least for C or C++ and similar languages) inlining across translation units, so is sometimes (improperly) called link-time optimization (LTO), but still is done by the compiler also running during the linking step. BTW, LTO existed at least since the 1990s (and probably even in the mainframe … WebAug 21, 2012 · Whether the "link-time optimization" (LTO) feature supported by recent versions of GCC is such an opportunity or not is yet to be proved, but Andi Kleen is determined to find out. The idea behind LTO is to examine the entire program after the individual files have been compiled and exploit any additional optimization opportunities …

WebJan 18, 2024 · January 18, 2024. This is the second article of a series discussing various methods of reducing the size of the Linux kernel to make it suitable for small environments. The first article provided a short rationale for this topic, and covered the link-time garbage collection, also called the ld --gc-sections method. WebMay 27, 2024 · Link time optimizations (abbr. LTO) are just that, optimizations done during linking. Linker is aware of all the compilation units and can optimize more compared to what conventional compiler can do. The most important optimizations that linker does are inlining and code locality improvements.
WebJun 18, 2024 · GCC 8.1 was released and Linux distros are starting to pick it up. This week hit the openSUSE Thumbleweed update with full rebuild (thanks to Martin Liška). Thus it is good time to look back into what changed in my favourite areas of the compiler. Here I will focus on the Inter-procedural optimization and link-time optimization (LTO). Websys-devel/gcc. Build using Link Time Optimizations (LTO). Note that GCC is always built with support for building other programs with LTO. This USE flag is for whether GCC itself is built and optimized with LTO. dev-lang/R. Use link-time optimization for R and its recommended packages. www-client/firefox.

WebFeb 20, 2024 · This change makes link-time optimization a more transparent replacement of per-file optimizations. It is now possible to build projects that require different optimization settings for different translation units (such as -ffast-math, -mavx, or -finline). Contrary to earlier GCC releases, the optimization and target options passed on the link ...
WebJan 26, 2014 · Another thing to take into account is optimizations that gcc does with the -O switch. You can specify various levels of optimization. The higher the optimization, the longer the compile and link times. A project I work with runs takes 2 minutes to link with -O3, and half a minute with -O1. You should make sure you're not optimizing more than ...
