Commit a3bc0401d436d8c7d2dd5b54e13b81333d53bdff by walter erquinigo Fix 132e57bc597bd3f50174b7d286c43f76b47f11c1 Compile error found in http://lab.llvm.org:8011/builders/lldb-x86_64-debian/builds/17403/steps/build/logs/stdio Simple fix

Commit 8e69c3cde8eed94be226bdef1ff6cedda3a33bc4 by nikita.ppv [DAGCombiner] Fold fmin/fmax with INF / FLT_MAX Similar to D87415, this folds the various float min/max opcodes with a constant INF or -INF operand, or FLT_MAX / -FLT_MAX operand if the ninf flag is set. Some of the folds are only possible under nnan. The fminnum(X, INF) with nnan and fmaxnum(X, -INF) with nnan cases are needed to improve the VECREDUCE_FMIN/FMAX lowerings on X86, the rest is here for the sake of completeness.

Commit cfff88c03cf9e9b72906a41fd11e06721d54f293 by nikita.ppv [InstCombine] Simplify select operand based on equality condition For selects of the type X == Y ? A : B, check if we can simplify A by using the X == Y equality and replace the operand if that's possible. We already try to do this in InstSimplify, but will only fold if the result of the simplification is the same as B, in which case the select can be dropped entirely. Here the select will be retained, just one operand simplified. As we are performing an actual replacement here, we don't have problems with refinement / poison values.

Commit 7c44ee8e1937c7402a106f3fa6a356caa73a14e8 by epastor [ms] [llvm-ml] Fix struct padding logic MASM structs are end-padded to have size a multiple of the smaller of the requested alignment and the size of their largest field (taken recursively, if they have a field of STRUCT type). This matches the behavior of ml.exe and ml64.exe. Our original implementation followed the MASM 6.0 documentation, which instead specified that MASM structs were padded to a multiple of their requested alignment.

Commit 53f36f06afbc02d1ab96e3789b41ddeafe31f40e by nikita.ppv [Legalize][ARM][X86] Add float legalization for VECREDUCE This adds SoftenFloatRes, PromoteFloatRes and SoftPromoteHalfRes legalizations for VECREDUCE, to fill the remaining hole in the SDAG legalization. These legalizations simply expand the reduction and let it be recursively legalized. For the PromoteFloatRes case at least it is possible to do better than that, but it's pretty tricky (because we need to consider the interaction of three different vector legalizations and the type promotion) and probably not really worthwhile. I haven't added ExpandFloatRes support, as I am not familiar with ppc_fp128. Differential Revision: https://reviews.llvm.org/D87569
