I'm wondering if there is any description on how to do this. For example, how do I get the assembly of a function and the -fdump-tree-all files from a gold based linking that goes as: rm -f test.s test2.s test.o test2.o ; gfortran -c -flto test.f90 ; gfortran -c -flto test2.f90 ; gfortran -O3 -march=native -fuse-linker-plugin -fwhopr=2 test.o test2.o just using -S or -fdump-tree-all doesn't work. Is 'objdump -d' the only tool ?
