Update compiler-rt to release_39 branch r288513. Since this contains a rather unfortunate upstream workaround for an unwind header problem that does not exist on FreeBSD, but which causes an unnecessary warning for us, add some flags to the compiler-rt Makefile to suppress the warning. 2016-12-02 15:17:41 -05:00			`.if ${COMPILER_TYPE} == "clang"`

libcompiler_rt: move file list to Makefile.inc for reuse elsewhere Also switch to the style used in the clang390-import branch to reduce future conflicts.

Enable libcompiler-rt on MIPS. Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an issue where __clzdi2 and __ctzdi2 would cause endless recursion. This bug has been fixed in r230021 already, but for some reason we only switched to libcompiler-rt on SPARC64 -- not MIPS. This means we can finally use <stdatomic.h> on all our architectures. 2013-04-20 10:44:28 -04:00			`.if ${MK_INSTALLLIB} != "no"`

On amd64 and i386, force assembler to mark objects compiled from the assembler source for libcompiler_rt as not needed executable stack. This is done with a hammer instead of properly marking each assembly file with section .note.GNU-stack to avoid modifying contributed source. Discussed with: ed 2011-01-07 09:35:45 -05:00			`.endif`
