Hi All
We are now optimizing some projects with lto enabled, however,
there are some issues.
First, lto_plugin.so needs to be passed to ar/nm/ranlib.
For example, build static library with lto:
gcc -flto -O2

Hi All
We are now optimizing some projects with lto enabled, however,
there are some issues.
First, lto_plugin.so needs to be passed to ar/nm/ranlib.
For example, build static library with lto:
gcc -flto -O2 a.c -c -o a.o
gcc -flto -O2 b.c -c -o b.o
ar rcs --plugin=/path/to/lto_plugin.so libx.
