------- Comment #23 from hjl dot tools at gmail dot com  2008-09-03 19:44 -------
On ira-merge branch at revision 139942, there are no regression
on Linux/ia32.  Linux/x86-64 has regressions:

+FAIL: gcc.target/i386/pr34256.c scan-assembler-times mov 2

Linux/ia64 has regressions:

+FAIL: gfortran.dg/list_read_8.f90  -O0  execution test
+FAIL: gfortran.dg/list_read_8.f90  -O1  execution test
+FAIL: gfortran.dg/list_read_8.f90  -O2  execution test
+FAIL: gfortran.dg/list_read_8.f90  -O3 -fomit-frame-pointer  execution test
+FAIL: gfortran.dg/list_read_8.f90  -O3 -fomit-frame-pointer -funroll-all-loops
-finline-functions  execution test
+FAIL: gfortran.dg/list_read_8.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test
+FAIL: gfortran.dg/list_read_8.f90  -O3 -g  execution test
+FAIL: gfortran.dg/list_read_8.f90  -Os  execution test

ligfortran is miscompiled since the executable runs correctly with
ligfortran from revision 139589.
