IPO: Specifying the amount of IPO/LTO jobs
Are there any plans to implement a way to decide the number of LTO/IPO servers/jobs?
The lack of this features makes the CMAKE_INTERPROCEDURAL_OPTIMIZATION useless for performance critical applications and requires writing custom flags for each compiler.
Adding a variable similar to CMAKE_INTERPROCEDURAL_OPTIMIZATION_JOBS which would accept a number and at zero defaults to auto(thin in clang) seems like one of the better previously proposed solutions.
This issue was mentioned previously but nothing was reached from what I am able to see.
