7.10.13 .cfi_offset register, offset Previous value of register is saved at offset offset from CFA. 7.10.14 .cfi_rel_offset register, offset Previous value of register is saved at offset offset from the current CFA register. This is transformed to .cfi_offset using the known displacement of...
即CFA定义为执行call xxx时SP(stack pointer)所指向的地址。 pushl %ebp .cfi_def_cfa_offset 8 .cfi_offset 5, -8 表示执行完pushl %ebp后SP与CFA偏了8字节(4字节return address,4字节ebp) movl %esp, %ebp .cfi_def_cfa_register 5 表示执行完movl %esp, %ebp后cfa_register不再是esp,而是ebp leave ....
.cfi_def_cfa_offset modifies a rule for computing CFA. Register remains the same, but offset is new. Note that it is the absolute offset that will be added to a defined register to compute CFA address. 7.10.12 .cfi_adjust_cfa_offset offset Same as .cfi_def_cfa_offset but offset is ...
CFI由三个部分组成:路径步骤(Path Steps)、偏移量(Offset)和文本位置(Text Location)。路径步骤用于指定导航路径,偏移量用于定位在该路径上的具体位置,文本位置用于定位在该位置上的具体文本。 1.3 CFI的格式 CFI的格式为"epubcfi(/要素路径[起始偏移量]/路径步骤[文本位置])"。其中,"epubcfi("是CFI标识符的开头...

Principle of non-compensation:This principle states that all aspects of an organization’s performance, whether positive or negative, are to be reported. In other words, it should not compensate (offset) a debt with an asset. Principle of prudence: All reporting of financial data is to be fac...
