* Remove autoconf supportChris Bieneman2016-01-2617-526/+0
| | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I felt a great disturbance in the [build system], as if millions of [makefiles] suddenly cried out in terror and were suddenly silenced. I fear something [amazing] has happened." - Obi Wan Kenobi Reviewers: chandlerc, grosbach, bob.wilson, tstellarAMD, echristo, whitequark Subscribers: chfast, simoncook, emaste, jholewinski, tberghammer, jfb, danalbert, srhines, arsenm, dschuff, jyknight, dsanders, joker.eph, llvm-commits Differential Revision: http://reviews.llvm.org/D16471 llvm-svn: 258861

* Add version, arch, system libs, and targets to Makefile.configNAKAMURA Takumi2014-02-091-0/+5
| | | | | | | | | | Teach autoconf/configure.ac to AC_SUBST several additional values in Makefile.config to make them available to Makefile code. These will be useful to generate CMake package modules from the Makefile build. Contributed by Brad King. llvm-svn: 201052
* Fix for executing AutoRegen.sh. Revert a part of r187209.Patrik Hagglund2013-09-131-0/+16
| | | | | | | | | | | | | | | | | Since r187209, which modified ltdl.m4, I was unable to execute AutoRegen.sh, getting: ../configure:10779: error: possibly undefined macro: AC_LTDL_FUNC_ARGZ This commit re-adds AC_LTDL_FUNC_ARGZ to ltdl.m4, as a quick fix. For me, this corresponds to the configure file currently checked in. (However, the ltdl library seems to be unused since r74924 in 2009, except for the use of the LTDL_SHLIB_EXT macro in bugpoint(?). Therefore, the right solution seems to try to get rid of the local ltdl.m4 file, specified by autoconf/README.TXT.) llvm-svn: 190677
* Link with -rdynamic instead of -Wl,-export-dynamic.Bob Wilson2013-08-021-4/+5
| | | | | | | | | | | | | | | Recent versions of the OS X linker support this but follow the existing OS X linker convention of using an underscore in the option name, i.e., -export_dynamic. Rather than changing our configure scripts to check for that alternate spelling, it is simpler to just use the compiler's -rdynamic option and let it deal with translating that to the appropriate linker option. One potential disadvantage of this approach is that the compiler will typically ignore -rdynamic on platforms where it is not supported, so the HAVE_LINK_EXPORT_DYNAMIC in config.h will not necessarily show whether that option has any effect or not. I don't see any in-tree uses of that macro, so I'm assuming it is OK. llvm-svn: 187686
* Remove dead or useless header checks from cmake and autoconfReid Kleckner2013-07-261-25/+3
| | | | | | | | | | On Windows, this improves clean cmake configuration time on my workstation from 1m58s to 1m32s, which is pretty significant. There's probably more that can be done here, but this is the low hanging fruit. Eric volunteered to regenerate ./configure for me. llvm-svn: 187209
* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. llvm-svn: 187179

* configure: when performing a compiler feature test for a -Wno-foo flag, attemptRichard Smith2013-02-081-1/+1
| | | | | | | | | to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of gcc, where it will silently accept an unknown -Wno-foo option, but will generate an error for a compile which uses -Wno-foo if that compile also triggers any warnings. llvm-svn: 174770

This is silently hidden in GCC-hosted builds because the inner main looks like a nested function declaration, which GCC supports. In builds with compilers which do not support nested functions (by default), this was causing an error, which caused these autoconf checks to fail, leaving their options disabled. This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu llvm-gcc selfhost builds, among other things. This also includes a regenerated configure, as the diff is small and telling. llvm-svn: 102288
