We're deferring fixing some of these that are obviously wrong to follow-up patches. Hopefully, the bugs are visible in the new test file (added at rL317220). As the description in Builtins.def says: "e = const, but only when -fmath-errno=0". This is step 2 of N to fix builtins and math calls as discussed in D39204.

* Basic: make the nan family pureSaleem Abdulrasool2017-10-171-3/+3
| | | | | | | | | | The nan family of math routines do not rely on global state. They do however depend on their parameter. This fits the description of pure: Functions which have no effects except the return value and their return value depends only on the parameters and/or global variables. Mark the family as `readonly`. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@315968 91177308-0d34-0410-b5e6-96231b3b80d8
* Basic: adjust attributes on `nan` LIBBUILTINsSaleem Abdulrasool2017-10-131-3/+3
| | | | | | | | | | | | The `nan` family of functions will inspect the contents of the parameter that they are passed. As a result, the function cannot be annotated as `const`. The documentation of the `const` attribute explicitly states this: Note that a function that has pointer arguments and examines the data pointed to must not be declared const. Adjust the annotations on this family of functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@315741 91177308-0d34-0410-b5e6-96231b3b80d8

* Add OpenCL 2.0 atomic builtin functions as Clang builtinYaxun Liu2017-08-041-0/+15
| | | | | | | | | | | | | | | | | | | | | | OpenCL 2.0 atomic builtin functions have a scope argument which is ideally represented as synchronization scope argument in LLVM atomic instructions. Clang supports translating Clang atomic builtin functions to LLVM atomic instructions. However it currently does not support synchronization scope of LLVM atomic instructions. Without this, users have to use LLVM assembly code to implement OpenCL atomic builtin functions. This patch adds OpenCL 2.0 atomic builtin functions as Clang builtin functions, which supports generating LLVM atomic instructions with synchronization scope operand. Currently only constant memory scope argument is supported. Support of non-constant memory scope argument will be added later.

| | | | | | | | | | | | | | | This allows for -fms-extensions to work the same on LP64. For example, _BitScanReverse is expected to be 32-bit, matching Windows/LLP64, even though long is 64-bit on x86_64 Darwin or Linux (LP64). Implement this by adding a new character code 'N', which is 'int' if the target is LP64 and the same 'L' otherwise Differential Revision: https://reviews.llvm.org/D34377 rdar://problem/32599746 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@305875 91177308-0d34-0410-b5e6-96231b3b80d8
* [XRay] Add __xray_customeevent(...) as a clang-supported builtinDean Michael Berris2017-05-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We define the `__xray_customeevent` builtin that gets translated to IR calls to the correct intrinsic. The default implementation of this is a no-op function. The codegen side of this follows the following logic: - When `-fxray-instrument` is not provided in the driver, we elide all calls to `__xray_customevent`. - When `-fxray-instrument` is enabled and a function is marked as "never instrumented", we elide all calls to `__xray_customevent` in that function; if either marked as "always instrumented" or subject to threshold-based instrumentation, we emit a call to the `llvm.xray.customevent` intrinsic from LLVM for each `__xray_customevent` occurrence in the function. This change depends on D27503 (to land in LLVM first).

| | | | | | | | | | | | | | | | | attributes. These patches don't work because we can't currently access the parameter information in a reliable way when building attributes. I thought this would be relatively straightforward to fix, but it seems not to be the case. Fixing this will requrie a substantial re-plumbing of machinery to allow attributes to be handled in this location, and several other fixes to the attribute machinery should probably be made at the same time. All of this will make the patch .... substantially more complicated.

* [X86] Implement __readgsqword (and the rest) as builtins (PR32373)Hans Wennborg2017-03-221-1/+0
| | | | | | | | | | | | | | It seems MS headers have started using __readgsqword, and since it's used in a header that doesn't include intrin.h, we can't implement it as an inline function anymore. That was already the case for __readfsdword, which Saleem added support for in r220859. This patch reuses that codegen to implement all of __read[fg]s{byte,word,dword,qword}.

* [nonnull] Teach Clang to attach the nonnull LLVM attribute toChandler Carruth2017-03-221-27/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | declarations and calls instead of just definitions, and then teach it to *not* attach such attributes even if the source code contains them. This follows the design direction discussed on cfe-dev here: http://lists.llvm.org/pipermail/cfe-dev/2017-January/052066.html The idea is that for C standard library builtins, even if the library vendor chooses to annotate their routines with __attribute__((nonnull)), we will ignore those attributes which pertain to pointer arguments that have an associated size. This allows the widespread (and seemingly reasonable) pattern of calling these routines with a null pointer and a zero size. I have only done this for the library builtins currently recognized by Clang, but we can now trivially add to this set. This will be controllable with -fno-builtin if anyone should care to do so. Note that this does *not* change the AST. As a consequence, warnings, static analysis, and source code rewriting are not impacted. This isn't even a regression on any platform as neither Clang nor LLVM have ever put 'nonnull' onto these arguments for declarations. All this patch does is enable it on other declarations while preventing us from ever accidentally enabling it on these libc functions due to a library vendor. It will also allow any other libraries using this annotation to gain optimizations based on the annotation even when only a declaration is visible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@298491 91177308-0d34-0410-b5e6-96231b3b80d8

This matches GCC. * Fix type of vfprintf to match its actual type. We gave it a wrong type due to PR4290 (apparently autoconf generates invalid code and expects compilers to choke it down or it miscompiles the program; the relevant error in clang was downgraded to a warning in r122744 to fix other occurrences of this autoconf brokenness, so we don't need this workaround any more). * Turn off vararg argument checking for __noop, since it's not *really* a varargs function.

* [OpenCL] Add to_{global|local|private} builtin functions.Yaxun Liu2016-05-201-0/+5
| | | | | | | | | | | | | | | | | | OpenCL builtin functions to_{global|local|private} accepts argument of pointer type to arbitrary pointee type, and return a pointer to the same pointee type in different addr space, i.e. global gentype *to_global(gentype *p); It is not desirable to declare it as global void *to_global(void *); in opencl header file since it misses diagnostics. This patch implements these builtin functions as Clang builtin functions. In the builtin def file they are defined to have signature void*(void*). When handling call expressions, their declarations are re-written to have correct parameter type and return type corresponding to the call argument. In codegen call to addr void *to_addr(void*) is generated with addrcasts or bitcasts to facilitate implementation in builtin library.

* Recommit: R258773 [OpenCL] Pipe builtin functionsXiuli Pan2016-01-261-0/+26
| | | | | | | | | | | | | | | | | | Fix arc patch fuzz error. Summary: Support for the pipe built-in functions for OpenCL 2.0. The pipe builtin functions may have infinite kinds of element types, one approach would be to just generate calls that would always use generic types such as void*. This patch is based on bader's opencl support patch on SPIR-V branch.
