------- Comment #6 from pinskia at gcc dot gnu dot org 2005-10-06 16:17 -------
This is a PRE bug as far as I can tell.
The diff between reassoc and PRE:
<bb 1>:
theTempManager_86 = theTemp$m_memoryManager_265(ab);
# VUSE <SFT.15_91>;
D.1851_87 = theTemp.m_memoryManager;
theTemp$m_memoryManager_268(ab) = D.1851_87;
# SFT.15_213 = V_MUST_DEF <SFT.15_91>;
theTemp.m_memoryManager = theTempManager_86;
# SFT.14_214 = V_MUST_DEF <SFT.14_94>;
theTemp.m_size = 0;
- # VUSE <SFT.15_213>;
- D.1852_90 = theTemp.m_memoryManager;
+ D.1852_90 = theTemp$m_memoryManager_265(ab);
# VUSE <SFT.14_214>;
# VUSE <SFT.15_213>;
D.1853_92 = D.1852_90->_vptr$MemoryManager;
# VUSE <SFT.14_214>;
# VUSE <SFT.15_213>;
D.1854_93 = *D.1853_92;
# SFT.14_215(ab) = V_MAY_DEF <SFT.14_214>;
# SFT.15_216(ab) = V_MAY_DEF <SFT.15_213>;
OBJ_TYPE_REF(D.1854_93;D.1852_90->0) (D.1852_90);
goto <bb 3> (<L47>);
Notice how both theTemp$m_memoryManager_265 and theTemp$m_memoryManager_268 are
alive.
