------- Comment #1 from dominiq at lps dot ens dot fr 2008-12-01 13:54 ------- AFAICT this pr is the cause of half of the failures of gfortran.dg/alloc_comp_constructor_1.f90 on i686-apple-darwin9 with -fdefault-integer-8:
FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O0 execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O0 scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O1 execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O1 scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O2 execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O2 scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer -funroll-loops execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer -funroll-loops scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -g execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -O3 -g scan-tree-dump-times original "builtin_free" 21 FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -Os execution test FAIL: gfortran.dg/alloc_comp_constructor_1.f90 -Os scan-tree-dump-times original "builtin_free" 21 The second half is due to 24 "builtin_free" in the "original" dump. This is the cause of some failures of this test on powerpc-apple-darwin9 (-O0/1, I have filled pr38347 against the middle-end for the ICE got with higher optimizations). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38324
