So, normally we'd punt approval to a language maintainer or some other maintainer up the food chain. :-) The style of test is a hand cuff from which escape would be annoying, if people didn't want them all to end with a period. Does someone else want to weigh in on good idea/bad idea here? I'd tend to think this is a fine patch and would like to just approve it, but am happy to listen to a counter argument if people don't like it, also happy to let someone else approve/reject it if they want. If no one feels strongly one way or other, I'll approve it. > [driver] Ensure --help=params lines end with period > > 2018-11-20 Tom de Vries <tdevr...@suse.de> > > PR c/79855 > * params.def (HOT_BB_COUNT_FRACTION): Terminate help message with > period. > > * lib/options.exp (check_for_options_with_filter): New proc. > * gcc.misc-tests/help.exp: Check that --help=params lines end with > period. > > --- > gcc/params.def | 2 +- > gcc/testsuite/gcc.misc-tests/help.exp | 2 ++ > gcc/testsuite/lib/options.exp | 34 ++++++++++++++++++++++++++++++---- > 3 files changed, 33 insertions(+), 5 deletions(-) > > diff --git a/gcc/params.def b/gcc/params.def > index 2ae5a007530..11396a7f3af 100644 > --- a/gcc/params.def > +++ b/gcc/params.def > @@ -397,7 +397,7 @@ DEFPARAM(PARAM_SMS_LOOP_AVERAGE_COUNT_THRESHOLD, > DEFPARAM(HOT_BB_COUNT_FRACTION, > "hot-bb-count-fraction", > "Select fraction of the maximal count of repetitions of basic block in > program given basic " > - "block needs to have to be considered hot (used in non-LTO mode)", > + "block needs to have to be considered hot (used in non-LTO mode).", > 10000, 0, 0) > DEFPARAM(HOT_BB_COUNT_WS_PERMILLE, > "hot-bb-count-ws-permille", > diff --git a/gcc/testsuite/gcc.misc-tests/help.exp > b/gcc/testsuite/gcc.misc-tests/help.exp > index f40cfabb41e..34ff9406e25 100644 > --- a/gcc/testsuite/gcc.misc-tests/help.exp > +++ b/gcc/testsuite/gcc.misc-tests/help.exp > @@ -63,6 +63,8 @@ check_for_options c "-v --help" "" {are likely to\n -std} > "" > # Try various --help= classes and qualifiers. > check_for_options c "--help=optimizers" "-O" " -g " "" > check_for_options c "--help=params" "maximum number of" > "-Wunsafe-loop-optimizations" "" > +check_for_options_with_filter c "--help=params" \ > + "^The --param option recognizes the following as parameters:$" "" > {[^.]$} "" > check_for_options c "--help=C" "-ansi" "-gnatO" "" > check_for_options c {--help=C++} {-std=c\+\+} "-gnatO" "" > check_for_options c "--help=common" "-dumpbase" "-gnatO" "" > diff --git a/gcc/testsuite/lib/options.exp b/gcc/testsuite/lib/options.exp > index 824d91276e4..60d85eea9d4 100644 > --- a/gcc/testsuite/lib/options.exp > +++ b/gcc/testsuite/lib/options.exp > @@ -26,11 +26,14 @@ if { [ishost "*-*-cygwin*"] } { > } > > # Run the LANGUAGE compiler with GCC_OPTIONS and inspect the compiler > -# output to make sure that they match the newline-separated patterns > -# in COMPILER_PATTERNS but not the patterns in COMPILER_NON_PATTERNS. > -# In case of failure, xfail if XFAIL is nonempty. > +# output excluding EXCLUDE lines to make sure that they match the > +# newline-separated patterns in COMPILER_PATTERNS but not the patterns in > +# COMPILER_NON_PATTERNS.
