2013-01-31Add support for AArch64 target.Tim Northover
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174055 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-12Check that the input size is correct for the given constraint.Bill Wendling
The 'a', 'c', and 'd' constraints on i386 mean a 32-bit register. We cannot place a 64-bit value into the 32-bit register.

2012-10-25Recommit Eric's code to validate ASM string's constraints and modifiers.Bill Wendling
This code checks the ASM string to see if the output size is able to fit within the variable specified as the output. For instance, scalar-to-vector conversions may not really work. It's on by default, but can be turned off with a flag if you think you know what you're doing. This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm'). <rdar://problem/12284092> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166737 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-13Add a per target max vector alignment field (e.g., 32-byte alignment for x86 ↵Chad Rosier
due to AVX). Currently, if no aligned attribute is specified the alignment of a vector is inferred from its size. Thus, very large vectors will be over-aligned with no benefit. Target owners should set this target max. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160209 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-30Introduce TargetInfo::hasFeature() to query various feature names inDouglas Gregor
each of the targets. Use this for module requirements, so that we can pin the availability of certain modules to certain target features, e.g., provide a module for xmmintrin.h only when SSE support is available. Use these feature names to provide a nearly-complete module map for Clang's built-in headers. Only mm_alloc.h and unwind.h are missing, and those two are fairly specialized at the moment.

2012-01-26Make clz/ctz builtins defined for zero on ARM targets. rdar://10732455Bob Wilson
ARM supports clz and ctz directly and both operations have well-defined results for zero. There is no disadvantage in performance to using the defined-at-zero versions of llvm.ctlz/cttz intrinsics. We're running into ARM-specific code written with the assumption that __builtin_clz(0) == 32, even though that value is technically undefined. The code is failing now because of llvm optimizations that are taking advantage of the undef behavior (specifically svn r147255). There's nothing wrong with that optimization on x86 where any incorrect assumptions about __builtin_clz(0) will quickly be exposed. For ARM, though, optimizations based on that undef behavior are likely to cause subtle bugs. Other targets with defined-at-zero clz/ctz support may want to override the default behavior as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149086 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-28Clean up a bit of the uses of CPU in the TargetInfo classes. This makesChandler Carruth
it an error if a CPU is provided for a target that doesn't implement logic handling CPU settings, to match the ABI settings. It also removes the CPU parameter from the getDefaultFeatures method. This parameter was always filled in with the same value as setCPU was called with, and at this point every single target implementation that referenced the CPU within this function has needed to store the CPU via setCPU anyways in order to implement other interface points. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140683 91177308-0d34-0410-b5e6-96231b3b80d8
