OpenJDK模板解释器中的模板表实现分为两部分:一部分是架构无关的公共代码,主要位于src/hotspot/share/interpreter/templateTable.hpp和src/hotspot/share/interpreter/templateTable.cpp中;一部分是架构相关的代码,主要位于src/hotspot/cpu/riscv/templateTable_riscv.hpp和src/hotspot/cpu/riscv/templateTable_riscv.cpp...
在TemplateInterpreterGenerator::set_short_entry_points()函数后，__pop(ltos)操作触发generate_and_dispatch()函数，调用模板表中的生成函数，即TemplateTable::lastore()函数。至此，解决模板表中opcode参数弹出问题，实现完整指令执行流程。
I want to check my understanding of how the imm[20|10:1|11|19:12] specifies the bit arrangements in the JAL (jump and link) instruction in RISC-V architecture? I know the opcode takes up the lower 7-bits, the destination register then uses the next 5-bits, totaling 12 bits. The ...
