Bug ID: 71566
Summary: Attribute [[aligned(16)]] on function is ignored
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: milasudril at gmail dot com
Target Milestone: ---
g++ does not accept [[aligned(16)]] as attribute on a function. However, the
non-standard notation works.
Example:
#include <cstdio>
__attribute__((aligned(16))) int test(int x)
{
printf("Address of test: %p\n",test);
return 0;
}
[[aligned(16)]] int test2(int x)
{
printf("Address of test2: %p\n",test2);
return 0;
}
int main()
{
test(0);
test2(0);
return 0;
}
g++ --version && g++ -std=c++14 -Wall main.cpp && ./a.out
