* Remove the mblaze backend from clang.Rafael Espindola2013-07-251-113/+0
| | | | | | Approval in here http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-July/064169.html llvm-svn: 187143
* Partial revert of r185568.Eli Bendersky2013-07-241-4/+0
| | | | | | | | r186899 and r187061 added a preferred way for some architectures not to get intrinsic generation for math builtins. So the code changes in r185568 can now be undone (the test remains). llvm-svn: 187079
* [PowerPC64] Fix passing of single-vector-member structs to match ABI.Bill Schmidt2013-07-231-2/+2
| | | | | | | | | | | | | | | | | The 64-bit PowerPC ELF ABI requires a struct that contains a single vector member to be passed in a vector register as though the wrapping struct were not present. Instead we were passing this as a byval struct. The same logic was already present for floating-point arguments, so this patch just extends the logic to handle vector types. The new test case verifies that clang coerces the parameter and annotates it as inreg. Thanks, Bill llvm-svn: 186993
* Simplify code. No functional change.Craig Topper2013-07-081-3/+1

* Add target hook CodeGen queries when generating builtin pow*.Eli Bendersky2013-07-031-0/+4
| | | | | | | | | | | Without fmath-errno, Clang currently generates calls to @llvm.pow.* intrinsics when it sees pow*(). This may not be suitable for all targets (for example le32/PNaCl), so the attached patch adds a target hook that CodeGen queries. The target can state its preference for having or not having the intrinsic generated. Non-PNaCl behavior remains unchanged; PNaCl-specific test added. llvm-svn: 185568
* Teach ARM va_arg to ignore empty structs.Tim Northover2013-06-211-0/+6
| | | | | | | | Empty structs are ignored for parameter passing purposes, but va_arg was incrementing the pointer anyway which could lead to va_list getting out of sync. llvm-svn: 184605
* Check for trivial constructibility before emptiness in ARM ABI.Tim Northover2013-06-211-3/+3
| | | | | | | | | | | | According to the Itanium ABI (3.1.1), types with non-trivial copy constructors passed by value should be passed indirectly, with the caller creating a temporary. We got this mostly correct, but forgot that empty structs can have non-trivial constructors too and passed them incorrectly. This simply reverses the order of the check. llvm-svn: 184603

* Diagnose malformed x86 inline asm using 'y' constraint.Tim Northover2013-06-071-1/+9
| | | | | | | | X86's 'y' inline assembly constraint represents an MMX register, this change prevents Clang from hitting an assertion when passed an incompatible type to deal with. llvm-svn: 183467
* Implement SparcV9ABIInfo::EmitVAArg.Jakob Stoklund Olesen2013-06-051-2/+46
| | | | | | | | | | | | This could actually be implemented with the LLVM IR va_arg instruction, but it doesn't seem to offer any advantages over accessing the va_list pointer directly. Using the va_list pointer directly makes it possible to perform type coercion directly from the argument array, and the va_list updates are exposed to the optimizers. llvm-svn: 183292

* Build correct coercion types in SparcV9ABIInfo.Jakob Stoklund Olesen2013-05-281-3/+127
| | | | | | | | | | | | | | | | The coercion type serves two purposes: 1. Pad structs to a multiple of 64 bits, so they are passed 'left-aligned' in registers. 2. Expose aligned floating point elements as first-level elements, so the code generator knows to pass them in floating point registers. We also compute the InReg flag which indicates that the struct contains aligned 32-bit floats. This flag is used by the code generator to pick the right registers. llvm-svn: 182753
* Add a SparcV9ABIInfo class for handling the standard SPARC v9 ABI.Jakob Stoklund Olesen2013-05-271-0/+93
| | | | | | | | | | | | | | | | - All integer arguments smaller than 64 bits are extended. - Large structs are passed indirectly, not using 'byval'. - Structs up to 32 bytes in size are returned in registers. Some things are not implemented yet: - EmitVAArg can be implemented in terms of the va_arg instruction. - When structs are passed in registers, float members require special handling because they are passed in the floating point registers. - Structs are left-aligned when passed in registers. This may require padding. llvm-svn: 182745
* Suffixing #pragma comment(lib) library names with .lib if necessary. This ↵Aaron Ballman2013-05-241-2/+13

* Forward #pragma comment(lib/linker) through as flags metadataReid Kleckner2013-05-081-2/+30
| | | | | | | | | | | | | | | | | | | | | | Summary: Most of this change is wiring the pragma all the way through from the lexer, parser, and sema to codegen. I considered adding a Decl AST node for this, but it seemed too heavyweight. Mach-O already uses a metadata flag called "Linker Options" to do this kind of auto-linking. This change follows that pattern. LLVM knows how to forward the "Linker Options" metadata into the COFF .drectve section where these flags belong. ELF support is not implemented, but possible. This is related to auto-linking, which is http://llvm.org/PR13016. CC: cfe-commits Differential Revision: http://llvm-reviews.chandlerc.com/D723 llvm-svn: 181426
* Add SystemZ supportUlrich Weigand2013-05-061-0/+290
| | | | | | | | | | | | | | This patch then adds all the usual platform-specific pieces for SystemZ: driver support, basic target info, register names and constraints, ABI info and vararg support. It also adds new tests to verify pre-defined macros and inline asm, and updates a test for the minimum alignment change. This version of the patch incorporates feedback from reviews by Eric Christopher and John McCall. Thanks to all reviewers! Patch by Richard Sandiford. llvm-svn: 181211

* This code works around what appears to be a bug in another part of clang.Reed Kotler2013-03-181-1/+2
| | | | | | | | | | | | I have filed http://llvm.org/bugs/show_bug.cgi?id=15538 against clang. This code is safer anyway because "cast" assumes you really know that it's okay to make the cast. In this case isa should not be false and dyn_cast should not return null as far as I understand. But everything else is valid so I did not want to revert my previous patch for attributes mips16/nomips16 or use an llvm_unreachable here which would make a number of our tests fail for mips. llvm-svn: 177329

* Change hasAggregateLLVMType, which conflates complex andJohn McCall2013-03-071-1/+1
| | | | | | | | | | | | | | | aggregate types in a profoundly wrong way that has to be worked around in every call site, to getEvaluationKind, which classifies and distinguishes between all of these cases. Also, normalize the API for loading and storing complexes. I'm working on a larger patch and wanted to pull these changes out, but it would have be annoying to detangle them from each other. llvm-svn: 176656
* Use the actual ABI-determined C calling convention for runtimeJohn McCall2013-02-281-28/+46
| | | | | | | | | | | | | | | | | | | | | | calls and declarations. LLVM has a default CC determined by the target triple. This is not always the actual default CC for the ABI we've been asked to target, and so we sometimes find ourselves annotating all user functions with an explicit calling convention. Since these calling conventions usually agree for the simple set of argument types passed to most runtime functions, using the LLVM-default CC in principle has no effect. However, the LLVM optimizer goes into histrionics if it sees this kind of formal CC mismatch, since it has no concept of CC compatibility. Therefore, if this module happens to define the "runtime" function, or got LTO'ed with such a definition, we can miscompile; so it's quite important to get this right. Defining runtime functions locally is quite common in embedded applications. llvm-svn: 176286
* Add support for AArch64 target.Tim Northover2013-01-311-0/+418
| | | | | | | | | | | | | In cooperation with the LLVM patch, this should implement all scalar front-end parts of the C and C++ ABIs for AArch64. 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. Further reviews would be gratefully received. llvm-svn: 174055

* This patch addresses varargs processing for small complex types underBill Schmidt2013-01-141-1/+39
| | | | | | | | | | | | | | | | | | | the 64-bit PowerPC ELF ABI. The ABI requires that the real and imaginary parts of a complex argument each occupy their own doubleword. Arguments smaller than 8 bytes are right-adjusted within the doubleword. Clang expects EmitVAARG() to return a pointer to a structure in which the real and imaginary parts are packed adjacently in memory. To accomplish this, we generate code to load the code appropriately from the varargs location and pack the values into a temporary variable in the form Clang expects, returning a pointer to that structure. The test case demonstrates correct code generation for all "small" complex types on PPC64: int, short, char, and float. llvm-svn: 172438
