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).

貢獻者指南

研究方向: 檢查 `src/jit/codegenarm.cpp` 中 `instGen Set Reg To Imm` 的當前實現。了解可重定位立即數和不可重定位立即數之間的區別。將該函數拆分為兩個：一個接受 `BYTE* addr` 用於可重定位立即數，另一個接受 `target ssize t imm` 用於不可重定位立即數。確保所有調用點相應更新。
