These are the bitcode at different stages of the LTO portion of the compile. LTO merges the IR for all files being linked and optimizes them as a single monolithic module. The preopt.bc is the merged IR just after merging and before performing any LTO optimizations. internalize.bc is after performing whole program internalization. opt.bc is after the optimization pipeline, and .precodegen.bc is

Hi I use the LDFLAGS=" -flto -fuse-ld=gold -Wl,-plugin-opt=save-temps " to generate the makefile and to make the whole program. However, found four different kinds of bitcode for each target. For example, I am compiling coreutils. For the program "nohup", I can get nohup.0.0.preopt.bc nohup.0.2.internalize.bc nohup.0.4.opt.bc nohup.0.5.precodegen.bc If I am right, I
