Constructor Details

EmuLinuxX86SyscallUseropLibrary

public EmuLinuxX86SyscallUseropLibrary(PcodeMachine<T> machine,
 EmuUnixFileSystem<T> fs,
 Program program)

Construct the system call library for Linux-x86

Parameters:

machine - the machine emulating the hardware

fs - the file system to export to the user-space program

program - a program containing syscall definitions and conventions, likely the target program

EmuLinuxX86SyscallUseropLibrary

public EmuLinuxX86SyscallUseropLibrary(PcodeMachine<T> machine,
 EmuUnixFileSystem<T> fs,
 Program program,
 EmuUnixUser user)

Construct the system call library for Linux-x86

Parameters:

machine - the machine emulating the hardware

fs - the file system to export to the user-space program

program - a program containing syscall definitions and conventions, likely the target program

user - the "current user" to simulate

Method Details

getAdditionalArchives

protected Collection<DataTypeManager> getAdditionalArchives()

Overrides:

getAdditionalArchives in class AnnotatedEmuSyscallUseropLibrary<T>

disposeAdditionalArchives

protected void disposeAdditionalArchives()

Overrides:

disposeAdditionalArchives in class AnnotatedEmuSyscallUseropLibrary<T>

swi

public void swi(PcodeExecutor<T> executor,
 PcodeUseropLibrary<T> library,
 Varnode out,
 int intNo)

Implement this to detect and interpret the INT 0x80 instruction as the syscall convention

Parameters:

executor - to receive the executor

library - to receive the userop library, presumably replete with syscalls

out - the output varnode

intNo - the interrupt number
