2011-03-21Provide a means for CrashRecovery clients to determine if code is currently ↵Ted Kremenek
running while crash recovery cleanups are being processed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128008 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-19Tweak CrashRecoveryContextCleanup to provide an easy method for clients to ↵Ted Kremenek
select between 'delete' and 'destructor' cleanups, and allow the destructor of CrashRecoveryContextCleanupRegister to be pseudo re-entrant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127929 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-18Tweak CrashRecoveryContextCleanup::createCleanup() to use the 'delete' ↵Ted Kremenek
cleanup as opposed to the 'destructor' cleanup (reclaims more memory). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127865 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-18Add new CrashRecoveryContextCleanup subclass: ↵Ted Kremenek
CrashRecoveryContextDeleteCleanup. This deletes the object, not just calls its destructor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127855 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-14Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort()John McCall
doesn't return, so just go back to using the old runtime function instead of trying to use abort() when __builtin_unreachable (or an equivalent) isn't supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127629 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-14Okay, some compilers complain if you provide the exception-specificationJohn McCall
where none was before. Just don't declare it and hope it's declared in every translation unit that needs it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127612 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-01Change directory_entry::path() to return a const std::string & instead ofDan Gohman
a StringRef, for the benefit of clients that want the result as a nul-terminated string. Clients that expect a StringRef will get one via the implicit conversion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126784 91177308-0d34-0410-b5e6-96231b3b80d8

need to be pulled out of the pass manager when the user specifies -fno-builtin. It can intelligently determine which libcalls to optimize based on what is enabled in TargetLibraryInfo.

for NSW/NUW binops to follow the pattern of exact binops. This allows someone to use Builder.CreateAdd(x, y, "tmp", MaybeNUW); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125270 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-09Rip out realpath() support. It's expensive, and often a bad idea, andDouglas Gregor
I have another way to achieve the same goal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125239 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-09Add llvm::sys::path::canonical(), which provides the canonicalizedDouglas Gregor
name of a path, after resolving symbolic links and eliminating excess path elements such as "foo/../" and "./". This routine still needs a Windows implementation, but I don't have a Windows machine available. Help? Please? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125228 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-09Rework InstrTypes.h so to reduce the repetition around the NSW/NUW/ExactChris Lattner
versions of creation functions. Eventually, the "insertion point" versions of these should just be removed, we do have IRBuilder afterall. Do a massive rewrite of much of pattern match. It is now shorter and less redundant and has several other widgets I will be using in other patches. Among other changes, m_Div is renamed to m_IDiv (since it only matches integer divides) and m_Shift is gone (it used to match all binops!!) and we now have m_LogicalShift for the one client to use. Enhance IRBuilder to have "isExact" arguments to things like CreateUDiv and reduce redundancy within IRbuilder by having these methods chain to each other more instead of duplicating code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125194 91177308-0d34-0410-b5e6-96231b3b80d8
