libctf warnings
Seen with every compiler I have if using -fno-inline:
home/alan/src/binutils-gdb/libctf/ctf-create.c: In function ‘ctf_add_encoded’:
/home/alan/src/binutils-gdb/libctf/ctf-create.c:555:3: warning: ‘encoding’ may be used uninitialized [-Wmaybe-uninitialized]
555 | memcpy (dtd->dtd_vlen, &encoding, sizeof (encoding));
Seen with gcc-4.9 and probably others at lower optimisation levels:
home/alan/src/binutils-gdb/libctf/ctf-serialize.c: In function 'symtypetab_density':
/home/alan/src/binutils-gdb/libctf/ctf-serialize.c:211:18: warning: 'sym' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (*max < sym->st_symidx)
Seen with gcc-4.5 and probably others at lower optimisation levels:
/home/alan/src/binutils-gdb/libctf/ctf-types.c:1649:21: warning: 'tp' may be used uninitialized in this function
/home/alan/src/binutils-gdb/libctf/ctf-link.c:765:16: warning: 'parent_i' may be used uninitialized in this function
Also with gcc-4.5:
