Hotspot7 hsdis PrintAssembly英特尔语法

java

每次-XX:+PrintAssembly与Hotspot一起使用时,都不得不烦恼我,不得不阅读可怕的AT&T语法。

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代码上

对于Intel Asm(我也更喜欢),只需添加以下内容

-XX:PrintAssemblyOptions=intel

如果您需要组合选项,请像这样用逗号分隔

-XX:PrintAssemblyOptions=intel,hsdis-help

任何未被识别为hsdis选项的内容都将被提供给反汇编程序,这些选项与您从中看到的选项相同

objdump --help

The following i386/x86-64 specific disassembler options are supported for use
with the -M switch (multiple options should be separated by commas):
