描述

As suggested in https://github.com/dotnet/coreclr/pull/19013#discussion_r204171338 the next step complement to dotnet/coreclr#19013 should be splitting instGen_Set_Reg_To_Imm in src/jit/codegenarm.cpp into two separate functions:

the one that accepts only relocatable immediate (as a BYTE* addr);
another one that accepts non-relocatable immediate (as a target_ssize_t imm).

贡献者指南

研究方向: 检查 `src/jit/codegenarm.cpp` 中 `instGen Set Reg To Imm` 的当前实现。了解可重定位立即数和不可重定位立即数之间的区别。将该函数拆分为两个：一个接受 `BYTE* addr` 用于可重定位立即数，另一个接受 `target ssize t imm` 用于不可重定位立即数。确保所有调用点相应更新。
