The 'g++.dg/lto/' parts of this pushed to master branch in
commit 94782ed70796427e6f4b15b1c2df91cd7bef28e8
"Skip a number of 'g++.dg/lto/' test cases for '-fno-exceptions' testing",
see attached.

Subject: [PATCH] Skip a number of 'g++.dg/lto/' test cases for
'-fno-exceptions' testing
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 "split files" test cases. For example:
[-PASS:-]{+UNSUPPORTED:+} g++.dg/lto/20081109-1 cp_lto_20081109-1_0.o [-assemble, -fPIC -flto -flto-partition=1to1-]{+assemble: exception handling disabled+}
[-PASS:-]{+UNRESOLVED:+} g++.dg/lto/20081109-1 cp_lto_20081109-1_0.o-cp_lto_20081109-1_0.o [-link,-]{+link+} -fPIC -flto -flto-partition=1to1
{+UNRESOLVED: g++.dg/lto/20081109-1 cp_lto_20081109-1_0.o-cp_lto_20081109-1_0.o execute -fPIC -flto -flto-partition=1to1+}
The "compile"/"assemble" tests (either continue to work, or) result in the
expected 'UNSUPPORTED: [...] compile: exception handling disabled', but
dependent "link" and "execute" tests then turn UNRESOLVED.
Specify 'dg-require-effective-target exceptions_enabled' for those test cases.
gcc/testsuite/
* g++.dg/lto/20081109-1_0.C: Specify
'dg-require-effective-target exceptions_enabled'.
* g++.dg/lto/20081109_0.C: Likewise.
* g++.dg/lto/20091026-1_0.C: Likewise.
* g++.dg/lto/pr87906_0.C: Likewise.
* g++.dg/lto/pr88046_0.C: Likewise.
