2012-01-05Replace the uint64_t -> double convertion algorithm with one that's more ↵Bill Wendling
efficient. This small bit of ASM code is sufficient to do what the old algorithm did: movq %rax, %xmm0 punpckldq (c0), %xmm0 // c0: (uint4){ 0x43300000U, 0x45300000U, 0U, 0U } subpd (c1), %xmm0 // c1: (double2){ 0x1.0p52, 0x1.0p52 * 0x1.0p32 } #ifdef __SSE3__ haddpd %xmm0, %xmm0 #else pshufd $0x4e, %xmm0, %xmm1 addpd %xmm1, %xmm0 #endif It's arguably faster. One caveat, the 'haddpd' instruction isn't very fast on all processors. <rdar://problem/7719814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147593 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-05Reapply r146997, "Heed spill slot alignment on ARM."Jakob Stoklund Olesen
Now that canRealignStack() understands frozen reserved registers, it is safe to use it for aligned spill instructions. It will only return true if the registers reserved at the beginning of register allocation allow for dynamic stack realignment. <rdar://problem/10625436> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147579 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-05Avoid reserving an ARM base pointer during register allocation.Jakob Stoklund Olesen
Once register allocation has started the reserved registers are frozen. Fix the ARM canRealignStack() hook to respect the frozen register state. Now the hook returns false if register allocation was started with frame pointer elimination enabled. It also returns false if register allocation started without a reserved base pointer, and stack realignment would require a base pointer. This bug was breaking oggenc on armv6. No test case, an upcoming patch will use this functionality to realign the stack for spill slots when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147578 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-05Freeze reserved registers before starting register allocation.Jakob Stoklund Olesen
The register allocators don't currently support adding reserved registers while they are running. Extend the MRI API to keep track of the set of reserved registers when register allocation started. Target hooks like hasFP() and needsStackRealignment() can look at this set to avoid reserving more registers during register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147577 91177308-0d34-0410-b5e6-96231b3b80d8

Using DenseMap iterators isn't free as they have to check for empty buckets. Dominator queries are common so this gives a minor speedup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147544 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-04use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJITSebastian Pop
Get back getHostTriple.
