Bug 641026 – sys-libs/compiler-rt-5.0.0: files contain writable and executable sections

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description Garri 2017-12-14 18:33:38 UTC]

After last update I got following QA notice:

The following files contain writable and executable sections:

!WX --- --- usr/lib/clang/5.0.0/lib/linux/libclang_rt.builtins-x86_64.a:chkstk.S.o
!WX --- --- usr/lib/clang/5.0.0/lib/linux/libclang_rt.builtins-x86_64.a:chkstk2.S.o
!WX --- --- usr/lib/clang/5.0.0/lib/linux/libclang_rt.builtins-i386.a:chkstk.S.o
!WX --- --- usr/lib/clang/5.0.0/lib/linux/libclang_rt.builtins-i386.a:chkstk2.S.o


Thanks.

See also https://bugs.llvm.org/show_bug.cgi?id=35739, and https://reviews.llvm.org/rL321431, which fixes this issue.

The chkstk and chkstk2 sources should simply not be built for Linux.

Mass-closing bugs reported for removed LLVM versions.  Feel free to reopen if the issue still applies and there is no newer report for it.
