Gold uses the libLTO interface. I think there is a small bug (strange design?) in libLTO: lto_codegen_write_merged_modules will write the bitcode files after they are merged and internalized, but before other optimizations are run. We should probably change that or add a new function to libLTO that gives us access to the optimized code. Can someone more familiar with libLTO comment why write_merged_modules writes the...

Hi, I am using gold plugin with the option "-use-gold-plugin -Wl,-plugin-opt=also-emit-llvm" to compile apache. I objdumped the final executable httpd to httpd.S. I also compiled those per file bytecode into native code using the following: llc filename.o llvm-gcc -c filename.o.s -o filename.o.o Then I objdumped filename.o.o to filename.o.S and compared some functions between
