Running 'make check' with: 'RUNTESTFLAGS=--target_board=unix/-fno-exceptions',
'error: exception handling disabled' is triggered for C++ 'throw' etc. usage,
and per 'gcc/testsuite/lib/gcc-dg.exp:gcc-dg-prune':
# If exceptions are disabled, mark tests expecting exceptions to be enabled
# as unsupported.
if { ![check_effective_target_exceptions_enabled] } {
if [regexp "(^|\n)\[^\n\]*: error: exception handling disabled" $text] {
return "::unsupported::exception handling disabled"
}
..., which generally means:
-PASS: [...] (test for excess errors)
+UNSUPPORTED: [...]: exception handling disabled
However, this doesn't work for 'g++.dg/tree-prof/' test cases. For example:
[-PASS:-]{+UNSUPPORTED:+} g++.dg/tree-prof/indir-call-prof-2.C [-compilation, -fprofile-generate -D_PROFILE_GENERATE-]{+compilation: exception handling disabled+}
[-PASS:-]{+UNRESOLVED:+} g++.dg/tree-prof/indir-call-prof-2.C execution, -fprofile-generate -D_PROFILE_GENERATE
[-PASS:-]{+UNRESOLVED:+} g++.dg/tree-prof/indir-call-prof-2.C compilation, -fprofile-use -D_PROFILE_USE
[-PASS:-]{+UNRESOLVED:+} g++.dg/tree-prof/indir-call-prof-2.C execution, -fprofile-use -D_PROFILE_USE
Dependent tests turn UNRESOLVED if the first "compilation" runs into the
expected 'UNSUPPORTED: [...] compile: exception handling disabled'.
Specify 'dg-require-effective-target exceptions_enabled' for those test cases.
