[Bug tree-optimization/43879] -fipa-pta causes various miscompilations

[rguenth at gcc dot gnu dot org]

------- Comment #12 from rguenth at gcc dot gnu dot org  2010-04-30 09:00 -------
With the last patch we are down to

                === libstdc++ tests ===


Running target unix/-fipa-pta/
FAIL: 23_containers/bitset/operations/1.cc execution test
FAIL: 23_containers/bitset/to_ullong/1.cc execution test

plus some gfortran procedure pointer tests (might be invalid or require
-fwhole-file to work) and 

FAIL: gcc.c-torture/execute/frame-address.c execution,  -O2

which is an invalid testcase with -fipa-pta (it gets optimized too far,
the stack frame is elided).
