Add a check to configure that the libstdc++ selected by Clang isn't libstdc++v4.6. This is quite hard to test directly, so we test for it by checking a known missing feature in that version that was added in v4.7.

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD. 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.

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD. This kind of simplification is sometimes useful, but in general it's not correct.

Add support for building with _GLIBCXX_DEBUG. New configure option --enable-expensive-checks allows the developer to enable runtime checking that can greatly increase compile time. Currently it only turns on _GLIBCXX_DEBUG. Other expensive debugging checks added later should be controlled by this configure option. This patch also updates llvm-config with a --cppflags option to inform llvm-gcc how to build itself so that it is compatible with an llvm that was built with _GLIBCXX_DEBUG. llvm-svn: 37777

[ADT][CMake][AutoConf] Fail-fast iterators for DenseMap Summary: This patch is an attempt at making `DenseMapIterator`s "fail-fast". Fail-fast iterators that have been invalidated due to insertion into the host `DenseMap` deterministically trip an assert (in debug mode) on access, instead of non-deterministically hitting memory corruption issues. Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`. `LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with `LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake / autoconf build system.

AArch64/ARM64: move ARM64 into AArch64's place This commit starts with a "git mv ARM64 AArch64" and continues out from there, renaming the C++ classes, intrinsics, and other target-local objects for consistency. "ARM64" test directories are also moved, and tests that began their life in ARM64 use an arm64 triple, those from AArch64 use an aarch64 triple. Both should be equivalent though. This finishes the AArch64 merge, and everyone should feel free to continue committing as normal now. llvm-svn: 209577

If this is used, the Mutex class will be implemented with all functions as no-op. Furthermore, linking against libpthread will not be done. Finally, the ParallelJIT example needs libpthread so its makefile was changed to always add -lpthread to the link line. llvm-svn: 23003

AC_SUBST(ALL_TARGETS,$ALL_TARGETS)
First step in avoiding compilation/usage of non-relevant targets. New options have been added to the configure script that control which targets will be used. The options are: --enable-target-this (default=disabled) This will specify that the target corresponding to the build host is the target that will be compiled/used. You can't use this with any of the other options (they'll be ignored). This is what most people want. --disable-target-x86 (default=enabled) This will prevent the X86 target(s) from being compiled/used. --disable-target-sparc (default=enabled) This will prevent both SparcV8 and SparcV9 from being compiled/used. --disable-target-powerpc (default=enabled) This will prevent the PowerPC target from being compiled/used. --disable-target-alpha (default=enabled) This will prevent the Alpha target from being compiled/used. --disable-target-ia64 (default=enabled) This will prevent the IA64 target from being compiled/used. Note that without any of these options, the default behavior is to build all targets, as is the current practice. All these options do is set up the substititution variable TARGETS_TO_BUILD which contains the targets that should be compiled/used. The variable is intended to be used in the makefiles. Those changes will come later. llvm-svn: 21445

First step in avoiding compilation/usage of non-relevant targets. New options have been added to the configure script that control which targets will be used. The options are: --enable-target-this (default=disabled) This will specify that the target corresponding to the build host is the target that will be compiled/used. You can't use this with any of the other options (they'll be ignored). This is what most people want. --disable-target-x86 (default=enabled) This will prevent the X86 target(s) from being compiled/used. --disable-target-sparc (default=enabled) This will prevent both SparcV8 and SparcV9 from being compiled/used. --disable-target-powerpc (default=enabled) This will prevent the PowerPC target from being compiled/used. --disable-target-alpha (default=enabled) This will prevent the Alpha target from being compiled/used. --disable-target-ia64 (default=enabled) This will prevent the IA64 target from being compiled/used. Note that without any of these options, the default behavior is to build all targets, as is the current practice. All these options do is set up the substititution variable TARGETS_TO_BUILD which contains the targets that should be compiled/used. The variable is intended to be used in the makefiles. Those changes will come later. llvm-svn: 21445

Target a minimal terminfo library rather than necessarily a full curses 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. llvm-svn: 188160

Add support for linking against a curses library when available and 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. llvm-svn: 187874

Introduce line editor library. This library will be used by clang-query. I can imagine LLDB becoming another client of this library, so I think LLVM is a sensible place for it to live. It wraps libedit, and adds tab completion support. The code is loosely based on the line editor bits in LLDB, with a few improvements: - Polymorphism for retrieving the list of tab completions, based on the concept pattern from the new pass manager. - Tab completion doesn't corrupt terminal output if the input covers multiple lines. Unfortunately this can only be done in a truly horrible way, as far as I can tell. But since the alternative is to implement our own line editor (which I don't think LLVM should be in the business of doing, at least for now) I think it may be acceptable. - Includes a fallback for the case where the user doesn't have libedit installed. Note that this uses C stdio, mainly because libedit also uses C stdio. Differential Revision: http://llvm-reviews.chandlerc.com/D2200 llvm-svn: 200595

[OCaml] [autoconf] Migrate to ocamlfind. This commit updates the OCaml bindings and tests to use ocamlfind. The bindings are migrated in order to use ctypes, which are now required for MCJIT-backed Llvm_executionengine. The tests are migrated in order to use OUnit and to verify that the distributed META.llvm allows to build working executables. Every OCaml toolchain invocation is now chained through ocamlfind, which (in theory) allows to cross-compile the OCaml bindings. The configure script now checks for ctypes (>= 0.2.3) and OUnit (>= 2). The code depending on these libraries will be added later. The configure script does not check the package versions in order to keep changes less invasive. Additionally, OCaml bindings will now be automatically enabled if ocamlfind is detected on the system, rather than ocamlc, as it was before. llvm-svn: 220899

Link with -rdynamic instead of -Wl,-export-dynamic. 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

Add time getters to the process interface for requesting the elapsed wall time, user time, and system time since a process started. For walltime, we currently use TimeValue's interface and a global initializer to compute a close approximation of total process runtime. For user time, this adds support for an somewhat more precise timing mechanism -- clock_gettime with the CLOCK_PROCESS_CPUTIME_ID clock selected. For system time, we have to do a full getrusage call to extract the system time from the OS. This is expensive but unavoidable. In passing, clean up the implementation of the old APIs and fix some latent bugs in the Windows code. This might have manifested on Windows ARM systems or other systems with strange 64-bit integer behavior. The old API for this both user time and system time simultaneously from a single getrusage call. While this results in fewer system calls, it also results in a lower precision user time and if only user time is desired, it introduces a higher overhead. It may be worthwhile to switch some of the pass timers to not track system time and directly track user and wall time. The old API also tracked walltime in a confusing way -- it just set it to the current walltime rather than providing any measure of wall time since the process started the way buth user and system time are tracked. The new API is more consistent here. The plan is to eventually implement these methods for a *child* process by using the wait3(2) system call to populate an rusage struct representing the whole subprocess execution. That way, after waiting on a child process its stats will become accurate and cheap to query. llvm-svn: 171551

Add support for linking against a curses library when available and 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.

dnl The curses library is optional; used for querying terminal info
Target a minimal terminfo library rather than necessarily a full curses 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. llvm-svn: 188160

Introduce line editor library. This library will be used by clang-query. I can imagine LLDB becoming another client of this library, so I think LLVM is a sensible place for it to live. It wraps libedit, and adds tab completion support. The code is loosely based on the line editor bits in LLDB, with a few improvements: - Polymorphism for retrieving the list of tab completions, based on the concept pattern from the new pass manager. - Tab completion doesn't corrupt terminal output if the input covers multiple lines. Unfortunately this can only be done in a truly horrible way, as far as I can tell. But since the alternative is to implement our own line editor (which I don't think LLVM should be in the business of doing, at least for now) I think it may be acceptable. - Includes a fallback for the case where the user doesn't have libedit installed. Note that this uses C stdio, mainly because libedit also uses C stdio. Differential Revision: http://llvm-reviews.chandlerc.com/D2200 llvm-svn: 200595

Reapply patch from r62553, with a fix to avoid looking for an ffi.h that isn't there. This changes the interpreter to use libffi. After this patch, the interpreter will barely be able to call any external functions if built on a system without libffi installed (just enough to pass 'make check' really). But with libffi, we can now call any function that isn't variadic or taking a struct or vector parameter (but pointer to struct is fine). Patch by Alexei Svitkine! llvm-svn: 63723

[OCaml] [autoconf] Migrate to ocamlfind. This commit updates the OCaml bindings and tests to use ocamlfind. The bindings are migrated in order to use ctypes, which are now required for MCJIT-backed Llvm_executionengine. The tests are migrated in order to use OUnit and to verify that the distributed META.llvm allows to build working executables. Every OCaml toolchain invocation is now chained through ocamlfind, which (in theory) allows to cross-compile the OCaml bindings. The configure script now checks for ctypes (>= 0.2.3) and OUnit (>= 2). The code depending on these libraries will be added later. The configure script does not check the package versions in order to keep changes less invasive. Additionally, OCaml bindings will now be automatically enabled if ocamlfind is detected on the system, rather than ocamlc, as it was before. llvm-svn: 220899

dnl First, use autoconf provided macros for specific headers that we need
Remove and/or shorten many comments in configure.ac. Remove checks for many common Unix programs. Our build process currently assumes they are there and makes no provisions for any other world-views. (We can add some of these checks back at some later time if it should prove useful, but right now, we do not need to check to see whether "rm" exists.) Remove checks for many common standard C headers and functions. We assume ISO/ANSI C++, and we always use the <cfoo> versions of ANSI C's <foo.h> headers, so these checks will not help anything. Edit configure's warning messages for clarity and content. Change checks for "optional" programs to default to using "true" instead of "false", so that a failure to find, e.g., etags, will be less likely to result in make failing. No longer shall we check for --enable-purify or --with-purify options. No longer shall we propagate these to the Makefiles. configure regenerated using autoconf-2.57.

Fix configure to find arc4random via header files. ISSUE: On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a transitive dependency of libedit. If a system had libedit on it that was implemented in terms of libbsd.so, then the arc4random test, previously implemented as a linker test, would succeed with -ledit. However, on Ubuntu this would also require a #include <bsd/stdlib.h>. This caused a build breakage on configure-based Ubuntu 12.04 with libedit installed. FIX: This fix changes configure to test for arc4random by searching for it in the standard header files. On Ubuntu 12.04, this test now properly fails to find arc4random as it is not defined in the default header locations. It also tweaks the #define names to match the output of the header check command, which is slightly different than the linker function check #defines. I tested the following scenarios: (1) Ubuntu 12.04 without the libedit package [did not find arc4random, as expected] (2) Ubuntu 12.04 with libedit package [properly did not find arc4random, as expected] (3) Ubuntu 12.04 with most recent libedit, custom built, and not dependent on libbsd.so [properly did not find arc4random, as expected].

Fixed the enable/disable options. The AC_ARG_ENABLE macro does not perform the *action-if-not-given* code when the --disable option is used. Rather, the AC_ARG_ENABLE macro sets the $enableval variable, which then needs to be checked to determine if --enable, --disable, or neither was specified. llvm-svn: 7238

Link with -rdynamic instead of -Wl,-export-dynamic. 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
