I was just reading through a Phrack article which had disassembly in HP-UX. I read that there are two classes of functions which are possible under HP-UX and SPARC; lea开发者_JAVA技巧f and non-leaf fu
Is there a way I can read开发者_如何学C if statements being evaluated? I mean, like get the return value of realpath in-
Using GDB we can set breakpoints and step into the test program. Some开发者_Go百科times on continuing step by step we step into some library file like \"malloc.c\", which we might not be really intere
In gdb I can use call to run functions,but what if I want to run s开发者_高级运维ome additional assembly?Prior to GCC 5 (1), I don\'t know of a way to run arbitrary machine code unless you actually en
here is my sample program: #include<stdio.h> int main() { printf(\"hello good morning \\n\"); return 0;
(gdb) p it $2 = (item *) 0x6 (gdb) p *it $3 = {next = 0x0, prev = 0x0, h_next = 0x0, time = 0, exptime = 0, nbytes = 7, refcount = 1, nsuff开发者_JAVA技巧ix = 6 \'\\006\', it_flags = 2 \'\\002\', slab
Step over occationally steps to previous line using gdb with both -g and -O2 flags. Remove the -O2 flags and it works as expected. Can anyone explain why that happens ?
So I have a program that works, but when I add more local variables, it blows up. Added code: double prMaxT, prMinT, poMaxT, poMinT, linT;
