<pre>Hi,
when compiling this 2-liner:
$ cat > test.c
static int x;
static int y __attribute__((alias("x")));
$ clang-8 -c -o test.o test.c
$ objdump -t test.o
test.o: file format elf64-x86-64
SYMBOL TABLE:
0000000000000000 l df *ABS* 0000000000000000 test.c
0000000000000000 l O .bss 0000000000000004 x
0000000000000000 g O .bss 0000000000000004 y
The "y" symbol ends up global (g) instead of the expected static (l).
ELF visibility attributes don't seem to work either.
Behaviour is the same on
* clang version 8.0.0 (tags/RELEASE_800/final)
* clang version 7.0.1-8 (tags/RELEASE_701/final)
Cheers,
David</pre>
