1、删除gcId.hpp #274

axiangyushanhaijing commented 1 year ago

针对 #96 中关于hotspot/agent/src/os/linux/LinuxDebuggerLocal.c 重新review发现问题，修改后提交 #283

axiangyushanhaijing commented 1 year ago

284 ,参考aarch64修改javaFrameAnchor_riscv64.hpp

axiangyushanhaijing commented 1 year ago

285 删除USE_LIBRARY_BASED_TLS_ONLY ，review代码发现此处defined是多余的。

286 Add support for riscv64 in LinuxCDebugger.java

287 删除 JfrTime::time_function中关于rv的支持。

288 增加libproc.h中关于rv的支持。

关于riscv中引入lea实现的地方需要重新review image 已提#289 并删除其他调用lea的地方，以及注释掉lea实现代码。

290 参考aarch64，添加can_be_compiled的实现代码。

291 参考aarch64, 将generate_method_handle_interpreter_entry中的lhu修改为lbu

292

Fix gen_i2c_adapter & generate_deopt_entry_for gen_i2c_adapter-->static Add dispatch_next in generate_deopt_entry_for

301 新增了is_dtrace_trap

302

1.delete #include "adfiles/ad_riscv64.hpp" in hotspot/src/cpu/riscv64/vm/sharedRuntime_riscv64.cpp

2.replace MethodData with MethodCounters in hotspot/src/cpu/riscv64/vm/templateInterpreterGenerator_riscv64.cpp

3.initializa offset in templateInterpreterGenerator_riscv64.cpp about la_patchable

303

Add EnableInvokeDynamic

axiangyushanhaijing commented 1 year ago

在本地新建一个release-temp的分支

axiangyushanhaijing commented 1 year ago

添加了 rv64关于内核相关的支持：#315 数值来源于 https://github.com/torvalds/linux/blob/master/arch/riscv/kernel/syscall_table.c

axiangyushanhaijing commented 1 year ago

316 修改了generate_method_handle_dispatch下vmIntrinsics::_linkToVirtual:的实现，其中重复ld操作。

axiangyushanhaijing commented 1 year ago

318 解决了当前的javac问题。
