Hi,
A question: it seems like this messes with alignment on functions?
So with input program al.c:
__attribute__((aligned(64)))
void alignedfn(void) {
__asm("nop");
}
void alignedfn2(void) {
__asm("nop");
}
int main(void){}
if we compile with -fsanitize=function we get:
-> clang al.c -o al.o -c -fsanitize=function
-> nm al.o
0000000000000008 T alignedfn
0000000000000018 T alignedfn2
0000000000000028 T main
So alignedfn and alignedfn2 doesn't seem to be aligned as we said.
Without -fsanitize=function:
-> clang al.c -o al.o -c
-> nm al.o
0000000000000000 T alignedfn
0000000000000010 T alignedfn2
0000000000000020 T main
I guess the data put before the functions get aligned but not the functions
themselves. Should I write a ticket about this?
