diffbench

Analysis of different versions of go compilers, pgo debug information and inline and escape analysis information display inline optimization differences

Use

flag information:

  -new string
        new benchmark output file
  -old string
        old benchmark output file

use example:

a command like this gets pgo debug information and inline and escape analysis information:

go build -gcflags=all="-d=pgodebug=1 -m" 2> old.txt

diffbench -new /new.txt -old /old.txt

output structare is:

// old inline , but new not inline
......(if have difference)
----------------
// new inline , but old not inline
......(if have difference)
