Use CHAR_BIT instead of NBBY in libctf
On x86-64 Fedora 29, I tried to build a mingw-hosted gdb that targets ppc-linux. You can do this with: ../binutils-gdb/configure --host=i686-w64-mingw32 --target=ppc-linux \ --disable-{binutils,gas,gold,gprof,ld} The build failed with these errors in libctf: In file included from ../../binutils-gdb/libctf/ctf-create.c:20: ../../binutils-gdb/libctf/ctf-create.c: In function 'ctf_add_encoded': ../../binutils-gdb/libctf/ctf-create.c:803:59: error: 'NBBY' undeclared (first use in this function) dtd->dtd_data.ctt_size = clp2 (P2ROUNDUP (ep->cte_bits, NBBY) / NBBY); ^~~~ ../../binutils-gdb/libctf/ctf-impl.h:254:42: note: in definition of macro 'P2ROUNDUP' #define P2ROUNDUP(x, align) (-(-(x) & -(align))) ^~~~~ ../../binutils-gdb/libctf/ctf-create.c:803:59: note: each undeclared identifier is reported only once for each function it appears in dtd->dtd_data.ctt_size = clp2 (P2ROUNDUP (ep->cte_bits, NBBY) / NBBY); ^~~~ ../../binutils-gdb/libctf/ctf-impl.h:254:42: note: in definition of macro 'P2ROUNDUP' #define P2ROUNDUP(x, align) (-(-(x) & -(align))) ^~~~~ ../../binutils-gdb/libctf/ctf-create.c: In function 'ctf_add_slice': ../../binutils-gdb/libctf/ctf-create.c:862:59: error: 'NBBY' undeclared (first use in this function) dtd->dtd_data.ctt_size = clp2 (P2ROUNDUP (ep->cte_bits, NBBY) / NBBY); ^~~~ ../../binutils-gdb/libctf/ctf-impl.h:254:42: note: in definition of macro 'P2ROUNDUP' #define P2ROUNDUP(x, align) (-(-(x) & -(align))) ^~~~~ ../../binutils-gdb/libctf/ctf-create.c: In function 'ctf_add_member_offset': ../../binutils-gdb/libctf/ctf-create.c:1341:21: error: 'NBBY' undeclared (first use in this function) off += lsize * NBBY; ^~~~ ../../binutils-gdb/libctf/ctf-create.c: In function 'ctf_add_type': ../../binutils-gdb/libctf/ctf-create.c:1822:16: warning: unknown conversion type character 'z' in format [-Wformat=] ctf_dprintf ("Conflict for type %s against ID %lx: " ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../../binutils-gdb/libctf/ctf-create.c:1823:35: note: format string is defined here "union size differs, old %zi, new %zi\n", ^ ../../binutils-gdb/libctf/ctf-create.c:1822:16: warning: unknown conversion type character 'z' in format [-Wformat=] ctf_dprintf ("Conflict for type %s against ID %lx: " ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../../binutils-gdb/libctf/ctf-create.c:1823:44: note: format string is defined here "union size differs, old %zi, new %zi\n", ^ ../../binutils-gdb/libctf/ctf-create.c:1822:16: warning: too many arguments for format [-Wformat-extra-args] ctf_dprintf ("Conflict for type %s against ID %lx: " ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This patch fixes the actual errors in here. I did not try to fix the printf warnings, though I think someone ought to.
