Correctly treat 64 bit integers specified via the mode attribute as the 'long' type when that type is 64 bits wide, and the 'long long' type when 'long' is only 32 bits wide. This fixes PR6108. Also adds a bunch of test cases to ensure proper conversion between equally sized standard types and mode-specified types on both 32 and 64 bit targets. llvm-svn: 94527

Fix attribute((mode([word|unwind_word]))) for x32 Patch by H.J. Lu ``` typedef unsigned int gcc_word __attribute__((mode(word))); ``` and ``` typedef unsigned int gcc_unwind_word __attribute__((mode(unwind_word))); ``` define the largest unsigned integer types which can be stored in a general purpose register, which may not be the pointer type. For x32, they aren't pointer nor unsigned long. We should 1. Make getUnwindWordWidth and getRegisterWidth virtual, 2. Override them for x32, similar to hasInt128Type. 3. Use getRegisterWidth for __attribute__((mode(word))); This fixes PR 24706. Reviewers: rnk Differential Revision: http://reviews.llvm.org/D16779 llvm-svn: 259383

[Headers][mips] Add `__attribute__((__mode__(__unwind_word__)))` to the _Unwind_Word / _Unwind_SWord definitions The rationale of this change is to fix _Unwind_Word / _Unwind_SWord definitions for MIPS N32 ABI. This ABI uses 32-bit pointers, but _Unwind_Word and _Unwind_SWord types are eight bytes long. # The __attribute__((__mode__(__unwind_word__))) is added to the type definitions. It makes them equal to the corresponding definitions used by GCC and allows to override types using `getUnwindWordWidth` function. # The `getUnwindWordWidth` virtual function override in the `MipsTargetInfo` class and provides correct type size values.

Implementation of gcc mode attribute; this is significant because it fixes PR2204. Not too much to say about the implementation; it works in a similar way to the vector size attribute. At some point, we need to modify the targets to provide information about the appropriate types. llvm-svn: 51577

PR3691: Add support for complex modes. I also tossed in support for XF while I was at it. There are still a lot of diagnostics missing from this code, and it isn't completely correct for anything other than x86, but it should work correctly on x86 for valid cases. llvm-svn: 65935

Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing. This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc). Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute). llvm-svn: 319002

Recommited: Fix for PR16752. Second commit. PR16752: 'mode' attribute for unusual targets doesn't work properly Description: Troubles could be happened due to some assumptions in handleModeAttr function (see SemaDeclAttr.cpp). For example, it assumes that 32 bit integer is 'int', while it could be 16 bit only. Instead of asking target: 'which type do you want to use for int32_t ?' it just hardcodes general opinion. That doesn't looks pretty correct. Please consider the next solution: 1. In Basic/TargetInfo add getIntTypeByWidth and getRealTypeByWidth methods. Methods asks target for proper type for given bit width. 2. Fix handleModeAttr according to new methods in TargetInfo. Fixes: 1st Commit (Done): Add new methods for TargetInfo: getRealTypeByWidth and getIntTypeByWidth for ASTContext names are almost same(invokes new methods from TargetInfo): getIntTypeForBitwidth and getRealTypeForBitwidth 2nd Commit (Current): Fix SemaDeclAttr, handleModeAttr function.

Enable support for __float128 in Clang and enable it on pertinent platforms This patch corresponds to reviews: http://reviews.llvm.org/D15120 http://reviews.llvm.org/D19125 It adds support for the __float128 keyword, literals and target feature to enable it. Based on the latter of the two aforementioned reviews, this feature is enabled on Linux on i386/X86 as well as SystemZ. This is also the second attempt in commiting this feature. The first attempt did not enable it on required platforms which caused failures when compiling type_traits with -std=gnu++11. If you see failures with compiling this header on your platform after this commit, it is likely that your platform needs to have this feature enabled. llvm-svn: 268898
