Author: psmith Date: Thu Oct 26 05:02:03 2017 New Revision: 316657 URL: http://llvm.org/viewvc/llvm-project?rev=316657&view=rev Log: [libunwind] Always use unwind tables in tests For many targets setting -fno-exceptions will prevent unwinding tables from being generated for the test programs. As libunwind depends on the tables to unwind the stack several tests will fail.
This change always adds -funwind-tables so that even when -fno-exceptions is set unwind tables are generated. fixes PR33858 Differential Revision: https://reviews.llvm.org/D37484 Modified: libunwind/trunk/test/libunwind/test/config.py Modified: libunwind/trunk/test/libunwind/test/config.py URL: http://llvm.org/viewvc/llvm-project/libunwind/trunk/test/libunwind/test/config.py?rev=316657&r1=316656&r2=316657&view=diff ============================================================================== --- libunwind/trunk/test/libunwind/test/config.py (original) +++ libunwind/trunk/test/libunwind/test/config.py Thu Oct 26 05:02:03 2017 @@ -43,10 +43,11 @@ class Configuration(LibcxxConfiguration) def configure_compile_flags(self): self.cxx.compile_flags += ['-DLIBUNWIND_NO_TIMER'] - if self.get_lit_bool('enable_exceptions', True): - self.cxx.compile_flags += ['-funwind-tables'] - else: + if not self.get_lit_bool('enable_exceptions', True): self.cxx.compile_flags += ['-fno-exceptions', '-DLIBUNWIND_HAS_NO_EXCEPTIONS'] + # Stack unwinding tests need unwinding tables and these are not + # generated by default on all Targets. + self.cxx.compile_flags += ['-funwind-tables'] if not self.get_lit_bool('enable_threads', True): self.cxx.compile_flags += ['-D_LIBUNWIND_HAS_NO_THREADS'] self.config.available_features.add('libunwind-no-threads') _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
