...this issue: include <assert.h> int main() { struct V { char buf1[10]; int b; char buf2[10]; } var; char *p = &var.buf1[1], *q = &var.b; assert (__builtin_object_size (p, 0) == sizeof (var) - 1); return 0; } Thanks, Strahinja

I made a mistake here, I get zero same as you. I want to fix it to get correct value. On 16.03.2016. 19:28, Duncan P. N.

Optimizer doesn't know how to calculate the object size when it finds condition that cannot be eliminated. There is example: ----------------------------------------------- #include<stdlib.h> #define STATIC_BUF_SIZE 10 #define LARGER_BUF_SIZE 30 size_t foo(int flag) { char *cptr; char chararray[LARGER_BUF_SIZE]; char chararray2[STATIC_BUF_SIZE]; if(flag) cptr =

Hi everyone, I have a question about ARM 32 big endian calling convention. It's about sending small structures as function argument. For example if passing 3 chars in a structure should alignment in register (argument register for passing those chars in function) be right-adjusted ? LLVM (trunk version) is passing those chars left-adjusted in register, and trying to read them like they
