--- Comment #3 from Jamaika <lukaszcz18 at wp dot pl> --- I'm not referring to the GCC 11.3.1 comment itself. I meant why the .a file automatically adds and compiles c files from the avx2 and sse2 directories that I have not added. I was surprised that ar.exe is not a gcc product. Who is the creator?
