I've now successfully completed a sparcv9-sun-solaris2.11 bootstrap (sparc-sun-solaris2.11 for comparison with last night's bootstrap of an unpatched tree still running), so we're mostly good again. Thanks. However, I see a couple of regressions compared to the last successful bootstrap: +FAIL: gfortran.dg/maxloc_2.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (internal compiler error: Segmentation Fault) +FAIL: gfortran.dg/maxloc_2.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (test for excess errors) +UNRESOLVED: gfortran.dg/maxloc_2.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions compilation failed to produce executable +FAIL: gfortran.dg/minloc_1.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (internal compiler error: Segmentation Fault) +FAIL: gfortran.dg/minloc_1.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (test for excess errors) +UNRESOLVED: gfortran.dg/minloc_1.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions compilation failed to produce executable +FAIL: gfortran.dg/minlocval_3.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (internal compiler error: Segmentation Fault) +FAIL: gfortran.dg/minlocval_3.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions (test for excess errors) +UNRESOLVED: gfortran.dg/minlocval_3.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions compilation failed to produce executable +FAIL: gfortran.dg/minlocval_3.f90 -O3 -g (internal compiler error: Segmentation Fault) +FAIL: gfortran.dg/minlocval_3.f90 -O3 -g (test for excess errors) +UNRESOLVED: gfortran.dg/minlocval_3.f90 -O3 -g compilation failed to produce executable +FAIL: gfortran.dg/g77/19990826-3.f -O (internal compiler error: Segmentation Fault) +FAIL: gfortran.dg/g77/19990826-3.f -O (test for excess errors) +FAIL: ext/special_functions/hyperg/check_nan.cc (test for excess errors) +UNRESOLVED: ext/special_functions/hyperg/check_nan.cc compilation failed to produce executable +FAIL: ext/special_functions/hyperg/check_value.cc (test for excess errors) +UNRESOLVED: ext/special_functions/hyperg/check_value.cc compilation failed to produce executable +FAIL: ext/special_functions/hyperg/compile.cc (test for excess errors) +FAIL: tr1/5_numerical_facilities/special_functions/17_hyperg/check_nan.cc (test for excess errors) +UNRESOLVED: tr1/5_numerical_facilities/special_functions/17_hyperg/check_nan.cc compilation failed to produce executable +FAIL: tr1/5_numerical_facilities/special_functions/17_hyperg/check_value.cc (test for excess errors) +UNRESOLVED: tr1/5_numerical_facilities/special_functions/17_hyperg/check_value.cc compilation failed to produce executable +FAIL: tr1/5_numerical_facilities/special_functions/17_hyperg/compile.cc (test for excess errors) +FAIL: tr1/5_numerical_facilities/special_functions/17_hyperg/compile_2.cc (test for excess errors) for both 32 and 64-bit multilibs.
