2009-07-30Twines: Don't allow implicit conversion from integers, this is too tricky.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77605 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-30Switch obvious clients to Twine instead of utostr (when they were already usingDaniel Dunbar
a Twine, e.g., for names). - I am a little ambivalent about this; we don't want the string conversion of utostr, but using overload '+' mixed with string and integer arguments is sketchy. On the other hand, this particular usage is something of an idiom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77579 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-03Make SROA produce a vector only when the alloca is actually Chris Lattner
accessed at least once as a vector. This prevents it from compiling the example in not-a-vector into: define double @test(double %A, double %B) { %tmp4 = insertelement <7 x double> undef, double %A, i32 0 %tmp = insertelement <7 x double> %tmp4, double %B, i32 4 %tmp2 = extractelement <7 x double> %tmp, i32 4 ret double %tmp2 } instead, producing the integer code. Producing vectors when they aren't otherwise in the program is dangerous because a lot of other code treats them carefully and doesn't want to break them down. OTOH, many things want to break down tasty i448's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63638 91177308-0d34-0410-b5e6-96231b3b80d8

With the new world order, it can handle cases where the first store into the alloca is an element of the vector, instead of requiring the first analyzed store to have the vector type itself.
