      cmd/compile: rewrite f(g()) for multi-value g() during typecheck · d96b7fbf
      Matthew Dempsky authored
      This CL moves order.go's copyRet logic for rewriting f(g()) into t1,
      t2, ... = g(); f(t1, t2, ...) earlier into typecheck. This allows the
      rest of the compiler to stop worrying about multi-value functions
      appearing outside of OAS2FUNC nodes.
      
      This changes compiler behavior in a few observable ways:
      
      1. Typechecking error messages for builtin functions now use general
      case error messages rather than unnecessarily differing ones.
      
      2. Because f(g()) is rewritten before inlining, saved inline bodies
      now see the rewritten form too. This could be addressed, but doesn't
      seem worthwhile.
      
      3. Most notably, this simplifies escape analysis and fixes a memory
      corruption issue in esc.go. See #29197 for details.
      
      Fixes #15992.
      Fixes #29197.

      fmtsort: sort interfaces deterministically · 9d40fadb
      lukechampine authored
      Previously, the result of sorting a map[interface{}] containing
      multiple concrete types was non-deterministic. To ensure consistent
      results, sort first by type name, then by concrete value.
      
      Fixes #30398

      cmd/compile: fix false positives in isGoConst · 7fa195c1
      Matthew Dempsky authored
      isGoConst could spuriously return true for variables that shadow a
      constant declaration with the same name.
      
      Because even named constants are always represented by OLITERAL nodes,
      the easy fix is to just ignore ONAME nodes in isGoConst. We can
      similarly ignore ONONAME nodes.
      
      Confirmed that k8s.io/kubernetes/test/e2e/storage builds again with
      this fix.
      
      Fixes #30430.
