* Request init/fini array on FreeBSD 12 and laterDimitry Andric2018-06-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Summary: It seems a bad idea to change the default in the middle of a release branch due to possible changes in global ctor / dtor ordering between .ctors and .init_array. With FreeBSD 11.0's release imminent lets change the default now for FreeBSD 12 (the current development stream) and later. FreeBSD rtld has supported .init_array / .fini_array for many years. As of Jan 1 2017 all supported FreeBSD releases and branches will have support.

* Use -fuse-init-array if no gcc installation is found.Nico Weber2017-10-261-1/+2
| | | | | | | | | | | | | | | | clang currently uses .init_array instead of .ctors on Linux if it detects gcc 4.7+. Make it so that it also uses .init_array if no gcc installation is found at all – if there's no old gcc, there's nothing we need to be compatible with. icecc for example runs clang in a very small chroot, so before this change clang would use .ctors if run under icecc. And lld currently silently mislinks inputs with .ctors sections, so before this clang + icecc + lld would produce broken binaries.

| | | | | | | | | | | | | | | | | | | | | | | Restore the `-gz` option to the driver with some minor tweaks to handle the additional case for `-Wa,--compress-debug-sections`. This intends to make the compression of the debug information controllable from the driver. The following is the behaviour: -gz enable compression (ambiguous for format, will default to zlib-gnu) -gz=none disable compression -gz=zlib-gnu enable compression (deprecated GNU style zlib compression) -gz=zlib enable compression (zlib based compression) Although -Wa,-compress-debug-sections works, it should be discouraged when using the driver to invoke the assembler. However, we permit the assembler to accept the GNU as style argument --compress-debug-sections to maintain compatibility. Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally specific -g for debug information to be generated. llvm-svn: 306115

* Driver: add support for `-gz` and `-gz=`Saleem Abdulrasool2017-06-111-0/+19
| | | | | | | | | | | | | | | | | These options control the behaviour of the compression of debug info sections on ELF targets. Our behaviour slightly diverges from the behaviour of GCC. `-gz` maps to the `-compress-debug-sections` rather than `-compress-debug-sections=zlib` or `-compress-debug-sections=zlib-gnu`. This small divergence allows us to be compatible across versions of binutils (=zlib support was introduced in 2.26, while earlier versions only support =zlib-gnu). This also allows users to not have to worry about the version of the assembler they may be using if they are not using the IAS. Previously, users would have had to go through the internal option `-compress-debug-sectionss` and pass that through to the assembler, which is no longer needed. llvm-svn: 305165
