Info

Diagnostic Compiler Flags (XL Compilers) Diagnostic messages are given on the terminal and/or in a separate file -qreport: compilers generate a file name.lst for each source file -qlist: compiler listing including an object listing -qlistopt: options in effect during compilation included in listing Listen to the compiler! – -qflag=: – i: informal messages, w: warning messages, s: severe errors – Use -qflag=i:i to get all information – -qlistfmt=(xml|html)= 52
Example: Compilers Diagnostics subroutine mult(c,a,ndim) implicit none integer :: ndim,i,j double precision :: a(ndim),c(ndim,ndim) ! Loop do i=1,1000 do j=1,1000 enddo enddo c(i,j) = a(i) >>>>> LOOP TRANSFORMATION SECTION
