* [APFloat] Removed out of date comment from isNormal().Michael Gottesman2013-06-241-3/+0
| | | | | | | I already finished the isIEEENormal => isNormal transition. So isNormal is now IEEE-754R compliant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184687 91177308-0d34-0410-b5e6-96231b3b80d8
* [APFloat] Rename llvm::exponent_t => llvm::APFloat::ExponentType.Michael Gottesman2013-06-241-4/+4
| | | | | | | | | exponent_t is only used internally in APFloat and no exponent_t values are exposed via the APFloat API. In light of such conditions it does not make any sense to gum up the llvm namespace with said type. Plus it makes it clearer that exponent_t is associated with APFloat. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184686 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | The old isNormal is already functionally replaced by the method isFiniteNonZero in r184350 and all references to said method were replaced in LLVM/clang in r184356/134366. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184449 91177308-0d34-0410-b5e6-96231b3b80d8

* [APFloat] Added isFiniteNonZero predicate.Michael Gottesman2013-06-191-0/+1
| | | | | | | | | | | | | | | | | This is the first patch in a series of patches to rename isNormal => isFiniteNonZero and isIEEENormal => isNormal. In order to prevent careless errors on my part the overall plan is: 1. Add the isFiniteNonZero predicate with tests. I can do this in a method independent of isNormal. (This step is this patch). 2. Convert all references to isNormal with isFiniteNonZero. My plan is to comment out isNormal locally and continually convert isNormal references => isFiniteNonZero until llvm/clang compiles. 3. Remove old isNormal and rename isIEEENormal to isNormal. 4. Look through all of said references from patch 2 and see if we can simplify them by using the new isNormal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184350 91177308-0d34-0410-b5e6-96231b3b80d8

* IEEE-754R 5.7.2 General Operations is* operations (except for isCanonical).Michael Gottesman2013-06-041-7/+42
| | | | | | | | | | | | | | | Specifically the following work was done: 1. If the operation was not implemented, I implemented it. 2. If the operation was already implemented, I just moved its location in the APFloat header into the IEEE-754R 5.7.2 section. If the name was incorrect, I put in a comment giving the true IEEE-754R name. Also unittests have been added for all of the functions which did not already have a unittest. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183179 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce needsCleanup() for APFloat and APInt.Manuel Klimek2013-06-032-1/+7

* Use only explicit bool conversion operatorsDavid Blaikie2013-05-153-6/+12
| | | | | | | | | | | | | | | | | | | | | | | BitVector/SmallBitVector::reference::operator bool remain implicit since they model more exactly a bool, rather than something else that can be boolean tested. The most common (non-buggy) case are where such objects are used as return expressions in bool-returning functions or as boolean function arguments. In those cases I've used (& added if necessary) a named function to provide the equivalent (or sometimes negative, depending on convenient wording) test. One behavior change (YAMLParser) was made, though no test case is included as I'm not sure how to reach that code path. Essentially any comparison of llvm::yaml::document_iterators would be invalid if neither iterator was at the end. This helped uncover a couple of bugs in Clang - test cases provided for those in a separate commit along with similar changes to `operator bool` instances in Clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181868 91177308-0d34-0410-b5e6-96231b3b80d8

* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-261-77/+0
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null. Both the old and new versions take about 4.6 seconds (2.5 user) to finish. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180624 91177308-0d34-0410-b5e6-96231b3b80d8

* Cleanup the simplify_type implementation.Rafael Espindola2013-03-273-18/+4
| | | | | | | | | | | | | | | | | | | | As far as simplify_type is concerned, there are 3 kinds of smart pointers: * const correct: A 'const MyPtr<int> &' produces a 'const int*'. A 'MyPtr<int> &' produces a 'int *'. * always const: Even a 'MyPtr<int> &' produces a 'const int*'. * no const: Even a 'const MyPtr<int> &' produces a 'int*'. This patch then does the following: * Removes the unused specializations. Since they are unused, it is hard to know which kind should be implemented. * Make sure we don't drop const. * Fix the default forwarding so that const correct pointer only need one specialization. * Simplifies the existing specializations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178147 91177308-0d34-0410-b5e6-96231b3b80d8
