| | | | | | | | 'make VG=1', as in clang beware of the 42000 leaks reported by valgrind in the Constant.cpp + Type.cpp files. it needs fixing IMHO git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57245 91177308-0d34-0410-b5e6-96231b3b80d8

* Be more precise about which conversions of NaNsDale Johannesen2008-10-062-0/+31
| | | | | | | | | | are Inexact. (These are not Inexact as defined by IEEE754, but that seems like a reasonable way to abstract what happens: information is lost.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57218 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow scalarrepl to treat an all-zero GEP just as bitcast.Matthijs Kooijman2008-10-061-0/+24
| | | | | | | | This includes not marking a GEP involving a vector as unsafe, but only when it has all zero indices. This allows scalarrepl to work in a few more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57177 91177308-0d34-0410-b5e6-96231b3b80d8
* Actually run Obj-C++ tests if llvm-gcc supports.Duncan Sands2008-10-062-2/+2
| | | | | | | | | | | | Before there were two problems: (1) configure turned "obj-c++" into "obj" in the langs line; (2) the dejagnu library called it objc++ not obj-c++. Now the problem is that some of these tests don't pass! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57167 91177308-0d34-0410-b5e6-96231b3b80d8
* rewrite bswap matching to be more general, allowing arbitraryChris Lattner2008-10-051-1/+16
| | | | | | | | | | shifting and masking inside a bswap expr. This allows it to handle the cases from PR2842, which involve the intermediate 'or' expressions being shifted, not just the input value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57095 91177308-0d34-0410-b5e6-96231b3b80d8
* Ignore loads from and stores to local memory (i.e. allocas)Duncan Sands2008-10-041-0/+10
| | | | | | | | | when deciding whether to mark a function readnone/readonly. Since the pass is currently run before SROA, this may be quite helpful. Requested by Chris on IRC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57050 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in the local allocator's liveness computation where itDan Gohman2008-10-041-0/+31
| | | | | | | | | was setting kill flags on tied uses in two-address instructions. The kill flags were causing the allocator to think it could allocate the use and its tied def in different registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57039 91177308-0d34-0410-b5e6-96231b3b80d8
