[Mingw-w64-public] Linker plugin problem

Hi, The linker plugin with LTO seems not working. When I link a static library which only contains LTO-enabled slim objects, the flag -fuse-linker-plugin doesn't work. The linker always tell me some symbols are undefined. Is it a bug? What I use is: x86_64-4.9.0-release-win32-sjlj-rt_v3-rev1

Re: [Mingw-w64-public] Do I need -flto when building a static lib?

Are you using GCC 4.9.0? Since GCC 4.9.0, LTO-enabled object file doesn't contain normal object code but GIMPLE bytecode by default. If you want to link to a static library, you have to pass -fuse-linker-plugin to let it extract LTO segments, and AFAIK it's enabled by default when -flto is

Then you must experience the same thing as I did. 2014-04-26 21:24 GMT+08:00 lh_mouse lh_mo...@126.com: Yes gcc 4.9.0. Thread model: win32 gcc version 4.9.0 (i686-win32-sjlj-rev0, Built by MinGW-W64 project) 2014-04-26 -- Best regards, lh_mouse

Hi, Is it possible that only build the runtimes like libstdc++, libgcc_s_sjlj-1 with LTO enabled? Someone static link it with LTO can benefit form it. Thanks! 2013/9/24 xunxun xunxun1...@gmail.com 于 2013/9/24 星期二 22:21, Alexey Pavlov 写道: 2013/9/24 xunxun xunxun1...@gmail.com: 于 2013/9/24

I often get lots of internal compilation error with LTO, too. What make things more weird is that sometimes add LTO related options like -flto-partition=none can remove the problem and sometimes it can not. Thanks! 2013/9/24 Alexey Pavlov alex...@gmail.com 2013/9/24 TOCK Chiu stanley82

Re: [Mingw-w64-public] alias in Windows

You may specify the include folder by pass -I parameter to GCC. I think this is a better solution because it won't mess the environment variables up. For example pass -IC:\Users\Arbol One\Documents\dev\C++\Applications\development\intence\ruch\Donald

[Mingw-w64-public] A problem about LTO in Ruben's builds

Hi, There is a problem in Ruben's builds x86_64-w64-mingw32-gcc-4.8.0-win64_rubenvb.7z and x86_64-w64-mingw32-gcc-4.8.0-linux64_rubenvb.tar.xz. The simple code snippet below with argument -static -O2 -flto can reproduce the problem: #includeiostream int main(){ std::cout Foo = 101 std::endl;
