patch

When building on powerpc (powerpc64 is fine) on head (which uses Clang), the following command causes a build crash when compiled with -O2:
LD_LIBRARY_PATH=/wrkdirs/usr/ports/lang/perl5.32/work/perl-5.32.0 ./miniperl -Ilib make_ext.pl lib/auto/DB_File/DB_File.so  MAKE="/usr/bin/make" LIBPERL_A=libperl.so.5.32.0 LINKTYPE=dynamic

Compiling with -O1 is fine. Base GCC on stable/12 is fine, so only Clang needs this workaround.
Comment 1 Mathieu Arnold freebsd_committer freebsd_triage 2020-08-10 07:46:04 UTC 
Please make sure you report the problem upstream.
Comment 2 Piotr Kubaj freebsd_committer freebsd_triage 2020-08-10 12:15:56 UTC 
What upstream do you mean (Perl or LLVM)? LLVM 11 is already at RC1 and it will probably hit head soon. I don't know whether Perl with LLVM 11 and -O2 will build fine, but it's possible, in that case -O1 will be only a temporary workaround.

If LLVM 11 doesn't work as well, I will certainly report it to LLVM bugzilla.

Well, this is a patch for Perl, so the upstream is Perl here :-)
