Reference: qiling/arch/register.py

Read

• Reading from string "exa"

ql.reg.read("EAX")

• Reading from Unicorn Engine const

ql.reg.read(UC_X86_REG_EAX)

• Reading eax

eax = ql.reg.eax

Write

• Writing 0xFF to "eax"

ql.reg.write("EAX", 0xFF)

• Writing 0xFF to eax, via Unicorn Engine const

ql.reg.write(UC_X86_REG_EAX, 0xFF)

• Writing 0xFF to eax

ql.reg.eax =  0xFF

Cross architecture registers

• This is for pc and sp only.

ql.reg.arch_pc
ql.reg.arch_sp

• Reading from PC/SP on current arch, defined by ql.archtype

ql.reg.arch_pc = 0xFF
ql.reg.arch_sp = 0xFF

Get register table

• Getting the list of current arch register table

ql.reg.register_mapping()

Get register bit

• This is for architecture that comes with 64bit and 32bit register

• In 64bit environment this will return 64

ql.reg.bit("rax")

• In 64bit environment this will return 32

ql.reg.bit("eax")
