OpenJDK 64-Bit Server问题

[dreamflyings]

make verilog/make emu出现如下问题：

Connection:[DISPLAY_LOG_ENABLE] type:[func] source location:[SimTop] sink location:[AXI4RAM_1]
Connection:[logTimestamp] type:[func] source location:[SimTop] sink location:[AXI4RAM_1]

[warn] There were 2 deprecated function(s) used. These may stop compiling in a future release - you are encouraged to fix these issues.
[warn] Line numbers for deprecations reported by Chisel may be inaccurate; enable scalac compiler deprecation warnings via either of the following methods:
[warn]   In the sbt interactive console, enter:
[warn]     set scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation")
[warn]   or, in your build.sbt, add the line:
[warn]     scalacOptions := Seq("-unchecked", "-deprecation")
Done elaborating.

�1 targets Makefile:79: recipe for target 'build/SimTop.v' failed
make: *** [build/SimTop.v] Error 1

如果将

./build.sc:84:  override def forkArgs = Seq("-Xmx64G")
./build.sc:95:    override def forkArgs = Seq("-Xmx64G")
./out/XiangShan/test/forkArgs/meta.json:3:        "-Xmx64G"
./out/XiangShan/forkArgs/meta.json:3:        "-Xmx64G"

这些文件中的 jvm_args: -Xmx64G 改小点则可以通过，希望这个参数用户可配

正确的log文件如下：

[warn] There were 2 deprecated function(s) used. These may stop compiling in a future release - you are encouraged to fix these issues.
[warn] Line numbers for deprecations reported by Chisel may be inaccurate; enable scalac compiler deprecation warnings via either of the following methods:

可以手动改一下 build.sc，每个机器的环境不同，我们不好给一个最小值

gedit /root/riscv_cpu/XiangShan/build.sc #find all -Xmx64G #change to -Xmx16G
