Hi,
I have several pretty big projects, which compile pretty quickly without "linker time code generation", because most of it is actually exact the same (a big common library). With LTGC the common library needs to be compiled by the linker, so since there is about 70 of these projects, it takes considerably more time. But that's acceptable.
But then there are 2 largest projects (also containing the common library being the biggest portion) and they simply never get linked. No error, the linker is just working, for say an hour... nothing...
Looks like a bug to me...
Also, when testing the optimization settings, I found out, that the global optimizations actually do not increase speed for my applications. But they considerably lower the size of the executables.
