In x86 assembly, the overflow flag is set when an add or sub operation on a signed integer overflows, and the carry flag is set when an operation on an uns开发者_StackOverflow社区igned integer overflo
i\'m just about to learn inline assembly.the GCC inline assembly cookbook http://www.ethernut.de/en/documents/arm-inline-asm.html
I\'m having difficulty understanding the role constraints play in GCC inline assembly (x86).I\'ve read the manual, which explains exactly what each constraint does.The problem is tha开发者_运维问答t e
In my ongoing experimentation with GCC inline assembly, I\'ve run into a new problem regarding labels and inlined code.
Sometimes, mainly for optimization purposes, very simple operations are implemented as complicated and clumsy code.
I\'m trying to learn GCC inline assembly on Linux (x86), and my first experiment was to try and implement integer overflow detection for multiplication.It seems easy enough, but it is having side effe
I need to understand just 1 single instruction and accordingly I need to generify the things. I need to pass structures (Objects of User Defined Data Types) at runtime using following assembly code.
I have some code that basically needs to use a small expression in an assembly statement, where the expression is fairly trivial like i*4, but GCC doesn\'t seem to realize that at compile time (tried
The code below is just showing a Message Box on the screen. The addresses are hardcoded to facilitate:
This does not look too friendly: __asm(\"command 1\" \"command 2\" \"command 3\"); Do I really have to put a doublequote around 开发者_如何学Goevery line?
