From 6090a4a1b32fd7859d0ad5b7e9b240bd5fa04b3f Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 27 Aug 2021 17:47:46 +0000 Subject: Allow #pragma GCC in headers in conformtest No "#pragma GCC" pragma allows macro-expansion of its arguments, so no namespace issues arise from use of such pragmas in installed headers. Ignore them in conformtest tests of header namespace. Tested for x86_64, in conjunction with Paul's patch adding use of such pragmas to installed headers shared with gnulib. --- conform/conformtest.py | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'conform') diff --git a/conform/conformtest.py b/conform/conformtest.py index f0405b7186..b0ec8e7ed1 100644 --- a/conform/conformtest.py +++ b/conform/conformtest.py @@ -624,6 +624,14 @@ class HeaderTests(object): continue if re.match(r'# [1-9]', line): continue + if line.startswith('#pragma GCC '): + # No GCC pragma uses macro expansion, so no + # namespace issues arise from such pragmas.
