Fixes compilation on osx and arm64

This proposal introduces a new flag, `--long-range-sync`, that takes effect whenever the most recent state in the database (or genesis, if no database) is older than the weak subjectivity period...

Extremely slow and inefficient hash function for openArray[byte] for 64-bit systems

14

### Description The [murmurhash implemention](https://github.com/nim-lang/Nim/blob/77c04092e01c7f42b5697ec0ec9e71352f628023/lib/pure/hashes.nim#L306) uses 32-bit limbs (on 64-bit systems) and inserts range checking inside the loop causing it to perform extremely poorly due to branching and inability to...

Inefficient codegen when extracting field from temporary object

4

### Description The following snippet, of critical performance importance when working with [sum types](https://github.com/nim-lang/RFCs/issues/548), generates an inefficient copy, even though it can be seen that lifetimes are bounded in such...

Can't create empty openArray with int8

8

### Description ```nim var v: array[1, byte] echo v.toOpenArray(0'i8, -1'i8) ``` at runtime, this crashes with a Defect (!) ### Nim Version 2.0.6 ### Current Output ```text Error: conversion from...

### Summary When passing parameters to templates, subsitution may cause the parameter to be evaluated multiple times - warn when this happens ### Description ```nim proc f(): int = echo...

Inefficient codegen for field return

2

### Description ```nim type X = object v: string proc fff(input: string): X = X(v: input) proc ggg(input: string): X = fff(input) proc hhh(input: string): string = ggg(input).v # inefficient...

ICE "param not init" with templates and callbacks

3

### Example ```nim type Result[T, E] = object DataProc = proc(val: openArray[byte]) GetProc = proc (onData: DataProc): Result[bool, cstring] func get[T, E](self: Result[T, E]): T = discard template `[]`[T, E](self:...

when nimvm doesn't isolate symbols

3

### Description ```nim when nimvm: proc mytest(a: int) = echo a else: template mytest(a: int) = echo a + 42 proc xxx() = mytest(100) ``` the vm symbol shouldn't be...
