* Change the post-RA scheduler to iterate through theDan Gohman2009-02-031-9/+11
| | | | | | | | | basic-block segments bottom-up instead of top down. This is the first step in a general restructuring of the way register liveness is tracked in the post-RA scheduler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63643 91177308-0d34-0410-b5e6-96231b3b80d8
* Tevert part of the x86 subtarget logic changes: when -march=x86-64Dan Gohman2009-02-031-4/+5
| | | | | | | | | | | | | | | | is given, override the subtarget settings and enable 64-bit support. This restores the earlier behavior, and fixes regressions on Non-64-bit-capable x86-32 hosts. This isn't necessarily the best approach, but the most obvious alternative is to require -mcpu=x86-64 or -mattr=+64bit to be used with -march=x86-64 when the host doesn't have 64-bit support. This makes things little more consistent, but it's less convenient, and it has the practical drawback of requiring lots of test changes, so I opted for the above approach for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63642 91177308-0d34-0410-b5e6-96231b3b80d8

* Make SROA produce a vector only when the alloca is actually Chris Lattner2009-02-032-7/+39
| | | | | | | | | | | | | | | | | | | | | 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
