I want to compile a bunch of C++ files into raw machine code and the run it with a platform-dependent starter written in C. Something like
Can anyone explain to me why every constant in AT&T syntax has a \'$\' in front of it? Why do all registers have a \'%\'?开发者_Python百科
How would you write a function in C which does an atomic compare and swap on an integer value, using embedded machine code (assuming, say, x86 architecture)? 开发者_如何学JAVACan it be any more specif
Hi I am trying to find the memory address of where my data gets stored. This is the assembly code of the function.
I am trying to debug somewhat strange problem in the device driver for the PCIe FPGA device. Both the device driver and the FPGA image are developed in the house.
In .NET/Windows there is the PROCESSOR_ARCHITECTURE environment variable which identifies whether a running process is x32, x64 or IA64.
I have been a high-level coder, and architectures are pretty new to me, so I decided to read the tutorial on Assembly here:
I am following the brokenthorn operating development series to study about bootloader. In this page , these are the three line of code :
We have a measurement data processing application and currently all data is held as C++ float which means 32bit/4byte on our x86/Windows platform. (32bit Windows Application).
