cmd/compile: set stricter inlining threshold in large functions If we're compiling a large function, be more picky about how big the function we're inlining is. If the function is >5000 nodes, we lower the inlining threshold from a cost of 80 to 20. Turns out reflect.Value's cost is exactly 80. That's the function at issue in #26546. 20 was chosen as a proxy for "inlined body is smaller than the call would be". Simple functions still get inlined, like this one at cost 7: func ifaceIndir(t *rtype) bool { return t.kind&kindDirectIface == 0 } 5000 nodes was chosen as the big function size. Here are all the 5000+ node (~~1000+ lines) functions in the stdlib: 5187 cmd/internal/obj/arm (*ctxt5).asmout 6879 cmd/internal/obj/s390x (*ctxtz).asmout 6567 cmd/internal/obj/ppc64 (*ctxt9).asmout 9643 cmd/internal/obj/arm64 (*ctxt7).asmout 5042 cmd/internal/obj/x86 (*AsmBuf).doasm 8768 cmd/compile/internal/ssa rewriteBlockAMD64 8878 cmd/compile/internal/ssa rewriteBlockARM 8344 cmd/compile/internal/ssa rewriteValueARM64_OpARM64OR_20 7916 cmd/compile/internal/ssa rewriteValueARM64_OpARM64OR_30 5427 cmd/compile/internal/ssa rewriteBlockARM64 5126 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_50 6152 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_60 6412 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_70 6486 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_80 6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_90 6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_100 6534 cmd/compile/internal/ssa rewriteValuePPC64_OpPPC64OR_110 6675 cmd/compile/internal/gc typecheck1 5433 cmd/compile/internal/gc walkexpr 14070 cmd/vendor/golang.org/x/arch/arm64/arm64asm decodeArg There are a lot more smaller (~1000 node) functions in the stdlib.
