Hello,
I just had the first taste with the latest LTO merge on our port.
Compiler is configured with LTO enabled and built correctly.
I tried the following example:
a.c
extern void foo(int);
int main()
{ foo(20);
return 1;
}
b.c
#include <stdio.h>
void foo(int c)
{
printf("Hello world: %d\n", c);
}
compiled with:
firepath-elf-gcc -flto a.c b.c -save-temps -O2
I expected that foo should be inlined into main, but not. Both functions
of main and foo are present in a.s, while b.s contains the LTO code.
Did I miss something here? Are there new hooks I should specify or tune for
LTO? I checked the up-to-date internal manual and found nothing.
Thanks,
Bingfeng Mei
