* Clang has existing support for debuggers thatSean Callanan2012-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | want to provide "po"-like functionality which treats the result of an expression implicitly as "id" (if it is not otherwise known) and prints it as an Objective-C object. This has in the past been gated by the "DebuggerSupport" language option, but that is too general. Debuggers also provide other commands like "print" that do not make any assumptions about whether the object is an Objective-C object. This patch makes the assumption conditional on a new language option: DebuggerCastResultToId. I have also made corresponding modifications to the testsuite. llvm-svn: 149735

* Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325>Bob Wilson2012-02-031-0/+1
| | | | | | | | | That llvm change removed the -trap-func backend option, so that using -ftrap-function with clang would cause the backend to complain. Fix it by adding the trap function name to the CodeGenOptions and passing it through to the TargetOptions. llvm-svn: 149679

* Back out my heinous hack that tricked the module generation mechanismDouglas Gregor2012-02-022-39/+34
| | | | | | | | | | | | | | | | | | | | into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. llvm-svn: 149611

| | | | | | | | | | | | | And remove HAVE_CLANG_CONFIG_H, now that the header is generated in the autoconf build, too. (clang r149497 / llvm r149498) Also include the config.h header after all other headers, per the LLVM coding standards. It also turns out WindowsToolChain.cpp wasn't using the config header at all, so that include's just deleted now. llvm-svn: 149504
* Split compiler builtin module into "stdlib" builtins and "intrinsic"Douglas Gregor2012-01-311-26/+39

| | | | | | | | | | | | | single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there.

* Extend the ExternalASTSource interface to allow the AST source toDouglas Gregor2012-01-264-3/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | provide the layout of records, rather than letting Clang compute the layout itself. LLDB provides the motivation for this feature: because various layout-altering attributes (packed, aligned, etc.) don't get reliably get placed into DWARF, the record layouts computed by LLDB from the reconstructed records differ from the actual layouts, and badness occurs. This interface lets the DWARF data drive layout, so we don't need the attributes preserved to get the answer write. The testing methodology for this change is fun. I've introduced a variant of -fdump-record-layouts called -fdump-record-layouts-simple that always has the simple C format and provides size/alignment/field offsets. There is also a -cc1 option -foverride-record-layout=<file> to take the output of -fdump-record-layouts-simple and parse it to produce a set of overridden layouts, which is introduced into the AST via a testing-only ExternalASTSource (called LayoutOverrideSource). Each test contains a number of records to lay out, which use various layout-changing attributes, and then dumps the layouts. We then run the test again, using the preprocessor to eliminate the layout-changing attributes entirely (which would give us different layouts for the records), but supplying the previously-computed record layouts. Finally, we diff the layouts produced from the two runs to be sure that they are identical. Note that this code makes the assumption that we don't *have* to provide the offsets of bases or virtual bases to get the layout right, because the alignment attributes don't affect it. I believe this assumption holds, but if it does not, we can extend LayoutOverrideSource to also provide base offset information. Fixes the Clang side of <rdar://problem/10169539>. llvm-svn: 149055

* Some improvements to the handling of C11 atomic types:David Chisnall2012-01-161-0/+8
| | | | | | | | | | | | | | | | | | - Add atomic-to/from-nonatomic cast types - Emit atomic operations for arithmetic on atomic types - Emit non-atomic stores for initialisation of atomic types, but atomic stores and loads for every other store / load - Add a __atomic_init() intrinsic which does a non-atomic store to an _Atomic() type. This is needed for the corresponding C11 stdatomic.h function. - Enables the relevant __has_feature() checks. The feature isn't 100% complete yet, but it's done enough that we want people testing it. Still to do: - Make the arithmetic operations on atomic types (e.g. Atomic(int) foo = 1; foo++;) use the correct LLVM intrinsic if one exists, not a loop with a cmpxchg. - Add a signal fence builtin - Properly set the fenv state in atomic operations on floating point values - Correctly handle things like _Atomic(_Complex double) which are too large for an atomic cmpxchg on some platforms (this requires working out what 'correctly' means in this context) - Fix the many remaining corner cases llvm-svn: 148242

* Fix PR11685 by implementing -ffast-math and its various friends in theChandler Carruth2012-01-021-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Clang driver. This involves a bunch of silly option parsing code to try to carefully emulate GCC's options. Currently, this takes a conservative approach, and unless all of the unsafe optimizations are enabled, none of them are. The fine grained control doesn't seem particularly useful. If it ever becomes useful, we can add that to LLVM first, and then expose it here. This also fixes a few tiny bugs in the flag management around -fhonor-infinities and -fhonor-nans; the flags now form proper sets both for enabling and disabling, with the last flag winning. I've also implemented a moderately terrifying GCC feature where a language change is also provided by the '-ffast-math' flag by defining the __FAST_MATH__ preprocessor macro. This feature is tracked and serialized in the frontend but it isn't used yet. A subsequent patch will add the preprocessor macro and tests for it. I've manually tested that codegen appears to respect this, but I've not dug in enough to see if there is an easy way to test codegen options w/o relying on the particulars of LLVM's optimizations. llvm-svn: 147434
