* Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort()John McCall2011-03-14
| | | | | | | | | | 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
* Okay, some compilers complain if you provide the exception-specificationJohn McCall2011-03-14

* Remove deprecated macro names. Hopefully this will unbreak theDuncan Sands2010-10-25
| | | | | | | | | smooshlab build. The breakage seems to be due to a collision between LLVM's ATTRIBUTE_UNUSED and gcc's which was previously hidden due to header files being included in a lucky order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117260 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly.Duncan Sands2010-09-15
| | | | | | | | | | | | | | The problem was that the test for whether a compiler supports it or not was inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization and not needed for correctness, so wrongly thinking a compiler doesn't support it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not an optimization: getting it wrong is fatal: it needs to be set based on a configure test not testing the gcc version. Since dragonegg has moved to a different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just remove this macro. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113959 91177308-0d34-0410-b5e6-96231b3b80d8

* I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename itDuncan Sands2010-05-11
| | | | | | | | to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is the opposite, for future use by dragonegg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103495 91177308-0d34-0410-b5e6-96231b3b80d8
* don't use always_inline with gcc 3.4, it has some unimplemented featuresChris Lattner2010-03-03
| | | | | | | | and is too old to really care about the performance of the generated compiler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97662 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which areBill Wendling2009-12-28
| | | | | | | | mainly used in debugging and/or assert situations. It should make the compiler and the static analyzer stop nagging us about them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92181 91177308-0d34-0410-b5e6-96231b3b80d8

* Make sure that if anyone passes a name by accident for the isSignedDuncan Sands2009-11-16
| | | | | | | | | | | parameter of CreateIntCast then they get an error from the compiler (or from the linker with a non-gcc compiler). Another possibility is to flip the order of the DestTy and isSigned parameters, since you should then get a compiler warning if you try to use a char* for a Type*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88913 91177308-0d34-0410-b5e6-96231b3b80d8
