- Subject: Stack-based pseudos
I was thinking about stack-based pseudos in stack-reorg.c last night, and
realized they might be useful for solving other problems as well.
The previous problem I reported with function prologue/epilogue
scheduling:
http://gcc.gnu.org/ml/gcc-bugs/2003-02/msg01290.html
http://gcc.gnu.org/ml/gcc-bugs/2003-02/msg01322.html
...might be solvable by having a new barrier type which prevents movement
of stack-based pseudos across the barrier.
In addition, it seems applicable to;
http://gcc.gnu.org/ml/gcc-bugs/2003-03/msg00004.html
...to improve alias analysis on stack-based arrays.
Am I expecting too much, or are these solvable with stack-based pseudos?
