Hotspot7 hsdis PrintAssembly 英特尔语法

发布于 2025-01-07 07:52:12 字数 113 浏览 0 评论 0原文

每次我在 Hotspot 中使用 -XX:+PrintAssembly 并且必须阅读可怕的 AT&T 语法时，这都会让我很烦恼。

有没有办法告诉它使用英特尔语法？

您所需要做的就是将一些选项解析到 dis-asm.h 和 binutils 代码中

对于 intel Asm（我也更喜欢），只需添加以下

-XX:PrintAssemblyOptions=intel

如果您需要组合选项像这样使用逗号

-XX:PrintAssemblyOptions=intel,hsdis-help

任何不被识别为 hsdis 选项的内容都将被提供给反汇编程序，这些选项是相同的您看到的列表来自

objdump --help

... <SNIP A lot of --help text %<> ...
The following i386/x86-64 specific disassembler options are supported for use
with the -M switch (multiple options should be separated by commas):
  x86-64      Disassemble in 64bit mode
  i386        Disassemble in 32bit mode
  i8086       Disassemble in 16bit mode
  att         Display instruction in AT&T syntax
  intel       Display instruction in Intel syntax
  att-mnemonic
              Display instruction in AT&T mnemonic
  intel-mnemonic
              Display instruction in Intel mnemonic
  addr64      Assume 64bit address size
  addr32      Assume 32bit address size
  addr16      Assume 16bit address size
  data32      Assume 32bit data size
  data16      Assume 16bit data size
  suffix      Always display instruction suffix in AT&T syntax

All you need is to parse some options onto the dis-asm.h and binutils code

For intel Asm (which I also prefer) just add the following

-XX:PrintAssemblyOptions=intel

If you need to combine options do it with commas like so

-XX:PrintAssemblyOptions=intel,hsdis-help

Anything not recognised as a hsdis option will be fed to the disassembler, these options are the same ones you see listed from

objdump --help
