2018-08-13FreeBSD 11.0 lacks ELFCOMPRESS_ZLIBnaruse
FreeBSD 11.0 unfortunately lacks ELF compression definitions in their elf.h (sys/elf_common.h), and 11.1 introduced them. https://github.com/freebsd/freebsd/commit/b9167d33a12b8a6c279be9cd1005874728e808c9 Though we can add workaround, we simply drop support because FreeBSD 11.0 is already EOL at November 30, 2017. https://www.freebsd.org/security/unsupported.html git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64351 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-07-08addr2line.c: no need to keep fd around after mmapnormal
POSIX mmap(3) manpage stipulates mmap bumps the reference count of the file description. Thus keeping a file descriptor to maintain the reference is not necessary. If this didn't work, every extension .so would require a permanent FD, which is obviously not the case. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63908 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-11-18addr2line.c: fix r60841 for glibc before 2.22normal
SHF_COMPRESSED was not defined until glibc 2.22, and there are older distros (e.g. Debian 8.x jessie) which do not have this defined. Perhaps it is safe to define SHF_COMPRESSED to (1 << 11) ourselves, too, since ELF should be a standardized format. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60843 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
