--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I haven't noticed this myself because my ~/.dejagnurc contains:
if { [info exists v3-use-std-list] } {
# v3-dg-runtest supports running tests with multiple -std options.
set v3_std_list { 98 11 14 17 20 23 26 }
set target_list {
"unix{-D_GLIBCXX_ASSERTIONS,-D_GLIBCXX_USE_CXX11_ABI=0,-m32}" }
} else {
set target_list {
"unix{,-D_GLIBCXX_USE_CXX11_ABI=0,-std=gnu++2b,-std=gnu++11}" }
}
So I run all tests 21 times (seven -std options, each repeated for three target
boards).
