gcc, inline assembly - pushad/popad missing?
(1 answer)
Closed 6 years ago.
I'm trying to execute
asm("pushad"); yet it's throwing an error saying "invalid instruction mnemonic "pushad" and then shows the line. I couldn't find anything on google and it SHOULD work. I've also tried __pushad, _pushad and PUSHAD.
G++ uses the 16bit version, pusha

I got this error when debugging in VC++: _Scary->_Myhead was 0xDDDDDDDD. I would like to know what this error means, possible sources, and possible solutions. I think it may have something to do with std::map usage, but I'm not sure. For reference, the debugger leads me to a file called "xtree". Unfortunately, I have no idea how to reproduce this because it is a big project and I do not know why this error is occuring.

Why does Code blocks show me the error
error: in C++98 'pro' must be initialized by constructor, not by '{...}'|
When I use std::string pro{'A','B','C','D','E','F'};?
How can I fix this?
You are using C++ 98 standards and it doesn't support { } initialization.
You have two options...
use -std=c++0x flag while compiling to use newer C++ standards.
Do initialization in the constructor or somewhere else.

How will i know whether inline function is actually replaced at the place where it is called or not?
(10 answers)
Closed 8 years ago.
I am trying to diagnose a weird performance problem that I think is related to a failure of GCC to inline some function calls in C++, though I am not sure which function calls. Is there a flag to GCC to list all line numbers where inlining was performed?
The answer to your question is here:
C++: How will i know whether inline function is actually replaced?.
The question was slightly different from yours, but the responses are spot-on - and definitely enlightening. I encourage you to read them.
In answer to your question, however:-Winline will generate a warning if the compiler chooses not to inline:

Does there exist a static_warning?
Is there a way to implement non fatal messages at compile time just like static_assert do when its condition fail? Having a message that shows up always when the compiler encounters it is not enough, I want it to show up when, for example, a template is instantiated.
Would BOOST_STATIC_WARNING work for you?

Does someone know how to open an MFC application to get the source-code?
(I want to know how it works)
MFC is compiled from C++ source, so it can't be recovered. You can use a decompiler on it, but the source you get back won't be particularly instructive.
There's a good related question on debugging, disassembling and decompiling you can check for more links.
