The RegisterCoalescer understands overlapping live ranges where one register is defined as a copy of the other. With this change, register allocators using LiveRegMatrix can do the same, at least for copies between physical and virtual registers. When a physreg is defined by a copy from a virtreg, allow those live ranges to overlap: %CL<def> = COPY %vreg11:sub_8bit; GR32_ABCD:%vreg11 %vreg13<def,tied1> = SAR32rCL %vreg13<tied0>, %CL<imp-use,kill> We can assign %vreg11 to %ECX, overlapping the live range of %CL. llvm-svn: 163336

We will soon allow virtual register live ranges to overlap regunit live ranges when the physreg is defined as a copy of the virtreg: %EAX = COPY %vreg5 FOO %vreg5 BAR %EAX<kill> There is no real interference since %vreg5 and %EAX have the same value where they overlap. This patch prevents addKillFlags from adding virtreg kill flags to FOO where the assigned physreg is overlapping the virtual register live range. llvm-svn: 163335

Kill flags are difficult to maintain, and liveness queries are better handled by live intervals. Kill flags are reinserted after register allocation by addKillFlags(). llvm-svn: 163334

This patch uses a new ABIInfo implementation specific to the le32 target, rather than falling back to DefaultABIInfo. Its behavior is basically the same, but it also allows the regparm argument attribute. It also includes basic tests for argument codegen and attributes. llvm-svn: 163333

Enhances basic alias analysis to recognize phis whose first incoming values are NoAlias and whose other incoming values are just the phi node itself through some amount of recursion. Example: With this change basicaa reports that ptr_phi and ptr_phi2 do not alias each other. bb: ptr = ptr2 + 1 loop: ptr_phi = phi [bb, ptr], [loop, ptr_plus_one] ptr2_phi = phi [bb, ptr2], [loop, ptr2_plus_one] ... ptr_plus_one = gep ptr_phi, 1 ptr2_plus_one = gep ptr2_phi, 1 This enables the elimination of one load in code like the following: extern int foo; int test_noalias(int *ptr, int num, int* coeff) { int *ptr2 = ptr; int result = (*ptr++) * (*coeff--); while (num--) { *ptr2++ = *ptr; result += (*coeff--) * (*ptr++); } *ptr = foo; return result; } Part 2/2 of fix for PR13564. llvm-svn: 163319

If we can show that the base pointers of two GEPs don't alias each other using precise analysis and the indices and base offset are equal then the two GEPs also don't alias each other. This is primarily needed for the follow up patch that analyses NoAlias'ing PHI nodes. Part 1/2 of fix for PR13564. llvm-svn: 163317

This adds a transformation to SimplifyCFG that attemps to turn switch instructions into loads from lookup tables. It works on switches that are only used to initialize one or more phi nodes in a common successor basic block, for example: int f(int x) { switch (x) { case 0: return 5; case 1: return 4; case 2: return -2; case 5: return 7; case 6: return 9; default: return 42; } This speeds up the code by removing the hard-to-predict jump, and reduces code size by removing the code for the jump targets. llvm-svn: 163302
