- Subject: side effects of the compiler-generated calls
Hi,
gfortran generated code uses calls to routines with the names that begin
with “_gfortran_”, e.g. “_gfortran_set_std”, “_gfortran_st_write” etc.
What are the side effects of these routines? What registers are
used/affected by them? And most importantly, do they affect the value of
the stack pointer ( %esp )?
Thank you,
David
