2006-04-18Implement an important entry from README_ALTIVEC:Chris Lattner
If an altivec predicate compare is used immediately by a branch, don't use a (serializing) MFCR instruction to read the CR6 register, which requires a compare to get it back to CR's. Instead, just branch on CR6 directly. :) For example, for: void foo2(vector float *A, vector float *B) { if (!vec_any_eq(*A, *B)) *B = (vector float){0,0,0,0}; } We now generate: _foo2: mfspr r2, 256 oris r5, r2, 12288 mtspr 256, r5 lvx v2, 0, r4 lvx v3, 0, r3 vcmpeqfp. v2, v3, v2 bne cr6, LBB1_2 ; UnifiedReturnBlock LBB1_1: ; cond_true vxor v2, v2, v2 stvx v2, 0, r4 mtspr 256, r2 blr LBB1_2: ; UnifiedReturnBlock mtspr 256, r2 blr instead of: _foo2: mfspr r2, 256 oris r5, r2, 12288 mtspr 256, r5 lvx v2, 0, r4 lvx v3, 0, r3 vcmpeqfp. v2, v3, v2 mfcr r3, 2 rlwinm r3, r3, 27, 31, 31 cmpwi cr0, r3, 0 beq cr0, LBB1_2 ; UnifiedReturnBlock LBB1_1: ; cond_true vxor v2, v2, v2 stvx v2, 0, r4 mtspr 256, r2 blr LBB1_2: ; UnifiedReturnBlock mtspr 256, r2 blr This implements CodeGen/PowerPC/vec_br_cmp.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27804 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-18Have the AutoRegen.sh script prompt the user for the LLVM src and objReid Spencer
directories if it can't find them. Then, replace those values into the configure.ac script and pass them to the LLVM_CONFIG_PROJECT so that the values become the default for llvm_src and llvm_obj variables. In this way the user is required to input this exactly once, and the scripts take it from there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27798 91177308-0d34-0410-b5e6-96231b3b80d8

even/odd halves. Thanks to Nate telling me what's what. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27793 91177308-0d34-0410-b5e6-96231b3b80d8
2006-04-18Implement v16i8 multiply with this code:Chris Lattner
vmuloub v5, v3, v2 vmuleub v2, v3, v2 vperm v2, v2, v5, v4 This implements CodeGen/PowerPC/vec_mul.ll. With this, v16i8 multiplies are 6.79x faster than before. Overall, UnitTests/Vector/multiplies.c is now 2.45x faster with LLVM than with GCC. Remove the 'integer multiplies' todo from the README file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27792 91177308-0d34-0410-b5e6-96231b3b80d8
