2012-10-09misched: Remove LoopDependencies heuristic.Andrew Trick
This wasn't contributing anything significant to postRA heuristics except compile time (by my measurements) and will be replaced by a more general heuristic for cross-region dependencies within the scheduler itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165563 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-09Initial assembler implementation of Mips load address macroJack Carter
This patch provides initial implementation of load address macro instruction for Mips. We have implemented two kinds of expansions with their variations depending on the size of immediate operand: 1) load address with immediate value directly: * la d,j => addiu d,$zero,j (for -32768 <= j <= 65535) * la d,j => lui d,hi16(j) ori d,d,lo16(j) (for any other 32 bit value of j) 2) load load address with register offset value * la d,j(s) => addiu d,s,j (for -32768 <= j <= 65535) * la d,j(s) => lui d,hi16(j) (for any other 32 bit value of j) ori d,d,lo16(j) addu d,d,s This patch does not cover the case when the address is loaded from the value of the label or function.

DeadArgumentElimination pass can replace one LLVM function with another, invalidating a pointer stored in debug info metadata entry for this function.

2012-10-08Don't crash on extra evil irreducible control flow.Jakob Stoklund Olesen
When the CFG contains a loop with multiple entry blocks, the traces computed by MachineTraceMetrics don't always have the same nice properties. Loop back-edges are normally excluded from traces, but MachineLoopInfo doesn't recognize loops with multiple entry blocks, so those back-edges may be included. Avoid asserting when that happens by adding an isEarlierInSameTrace() function that accurately determines if a dominating block is part of the same trace AND is above the currrent block in the trace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165434 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-08Begin the transition to using the AttributesImpl object for the Attributes ivar.Bill Wendling
Start using the AttributesImpl object to hold the value of the attributes. All queries go through the interfaces now. This has one unfortunate consequence. I needed to move the AttributesImpl.h file into include/llvm. But this is only temporary! Otherwise, the changes needed to support this would be too large. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165433 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-08PR12716: PPC crashes on vector compareAdhemerval Zanella
Vector compare using altivec 'vcmpxxx' instructions have as third argument a vector register instead of CR one, different from integer and float-point compares. This leads to a failure in code generation, where 'SelectSETCC' expects a DAG with a CR register and gets vector register instead. This patch changes the behavior by just returning a DAG with the vector compare instruction based on the type. The patch also adds a testcase for all vector types llvm defines. It also included a fix on signed 5-bits predicates printing, where signed values were not handled correctly as signed (char are unsigned by default for PowerPC). This generates 'vspltisw' (vector splat) instruction with SIM out of range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165419 91177308-0d34-0410-b5e6-96231b3b80d8
