2013-10-06Windows: Add support for unicode command linesDavid Majnemer1-0/+1
Summary: The MSVCRT deliberately sends main() code-page specific characters. This isn't too useful to LLVM as we end up converting the arguments to UTF-16 and subsequently attempt to use the result as, for example, a file name. Instead, we need to have the ability to access the Unicode command line and transform it to UTF-8. This has the distinct advantage over using the MSVC-specific wmain() function as our entry point because: - It doesn't work on cygwin. - It only work on MinGW with caveats and only then on certain versions. - We get to keep our entry point as main(). :) N.B. This patch includes fixes to other parts of lib/Support/Windows s.t. we would be able to take advantage of getting the Unicode paths. E.G. clang spawning clang -cc1 would want to give it Unicode arguments.

2013-09-13Fix for executing AutoRegen.sh. Revert a part of r187209.Patrik Hagglund1-0/+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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190677 91177308-0d34-0410-b5e6-96231b3b80d8
2013-08-30[conf] Add config variable to disable crash related overrides.Daniel Dunbar1-13/+30
- We do some nasty things w.r.t. installing or overriding signal handlers in order to improve our crash recovery support or interaction with crash reporting software, and those things are not necessarily appropriate when LLVM is being linked into a client application that has its own ideas about how to do things. This gives those clients a way to disable that handling at build time. - Currently, the code this guards is all Apple specific, but other platforms might have the same concerns so I went for a more generic configure name. Someone who is more familiar with library embedding on Windows can handle choosing which of the Windows/Signals.inc behaviors might make sense to go under this flag. - This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code expects it to be undefined when disabled, but the autoconf check was just defining it to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189694 91177308-0d34-0410-b5e6-96231b3b80d8

2013-08-12Remove all checking for the various terminfo headers (term.h andChandler Carruth1-5/+0
curses.h). Finding these headers is next to impossible. For example, on Debian systems libtinfo-dev provides the terminfo reading library we want, but *not* term.h. For the header, you have to use libncurses-dev. And libncursesw-dev provides a *different* term.h in a different location! These headers aren't worth it. We want two functions the signatures of which are clearly spec'ed in sys-v and other documentation. Just declare them ourselves and call them. This should fix some debian builders and provide better support for "minimal" debian systems that do want color autodetection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188165 91177308-0d34-0410-b5e6-96231b3b80d8
2013-08-12Target a minimal terminfo library rather than necessarily a full cursesChandler Carruth1-14/+14
library for color support detection. This still will use a curses library if that is all we have available on the system. This change tries to use a smaller subset of the curses library, specifically the subset that is on some systems split off into a separate library. For example, if you install ncurses configured --with-tinfo, a 'libtinfo' is install that provides just the terminfo querying functionality. That library is now used instead of curses when it is available. This happens to fix a build error on systems with that library because when we tried to link ncurses into the binary, we didn't pull tinfo in as well. =] It should also provide an easy path for supporting the NetBSD libterminfo library, but as I don't have access to a NetBSD system I'm leaving adding that support to those folks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188160 91177308-0d34-0410-b5e6-96231b3b80d8
2013-08-07Add support for linking against a curses library when available andChandler Carruth1-0/+24
using it to detect whether or not a terminal supports colors. This replaces a particularly egregious hack that merely compared the TERM environment variable to "dumb". That doesn't really translate to a reasonable experience for users that have actually ensured their terminal's capabilities are accurately reflected. This makes testing a terminal for color support somewhat more expensive, but it is called very rarely anyways. The important fast path when the output is being piped somewhere is already in place. The global lock may seem excessive, but the spec for calling into curses is *terrible*. The whole library is terrible, and I spent quite a bit of time looking for a better way of doing this before convincing myself that this was the fundamentally correct way to behave. The damage of the curses library is very narrowly confined, and we continue to use raw escape codes for actually manipulating the colors which is a much sane system than directly using curses here (IMO). If this causes trouble for folks, please let me know. I've tested it on Linux and will watch the bots carefully. I've also worked to account for the variances of curses interfaces that I could finde documentation for, but that may not have been sufficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187874 91177308-0d34-0410-b5e6-96231b3b80d8
2013-08-02Link with -rdynamic instead of -Wl,-export-dynamic.Bob Wilson2-6/+7
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187686 91177308-0d34-0410-b5e6-96231b3b80d8

2013-07-26[PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2-1/+4
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187179 91177308-0d34-0410-b5e6-96231b3b80d8

2013-07-01The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.Sylvestre Ledru1-2/+9
This kind of simplification is sometimes useful, but in general it's not correct. As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the build definitions used for FreeBSD, whereas for userland-related issues we want to match the definitions used for other systems with Glibc. The current modification adjusts the build system so that they can be distinguished, and explicitly adds GNU/kFreeBSD to the build checks in which it belongs. Fixes bug #16444.

This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved.
