Hi, I am doing some modification to gcc's RTL code. I am trying to split a pseudo (old) into two pseudos (old and new) and rewriting some part of the code to replace the "old" pseudo by the "new" pseudo. I am using the "replace_rtx" function to perform the replacement. However I get "fatal error: internal consistency failure" when I try to execute any program.
The specific call that I make is: replace_rtx (insn, old_rtx, new_rtx); I notice that "replace_rtx" actually performs the replacement when I try to print the "insn" before and after the call. However, later on I get the error "internal consistency failure". I would like to know what are the cases in which this error is thrown. Is there any document which I can refer to? regards, Raj
