../../gcc/gcc/config/i386/i386.c: In function ‘tree_node*
ix86_vectorize_builtin_vec_perm(tree, tree_node**)’:
../../gcc/gcc/config/i386/i386.c:30005:30: error: ‘fcode’ is used uninitialized
in this function [-Werror=uninitialized]
The offending code in gcc/config/i386/i386.c appears to be...
static tree
ix86_vectorize_builtin_vec_perm (tree vec_type, tree *mask_type)
{
tree itype = TREE_TYPE (vec_type);
bool u = TYPE_UNSIGNED (itype);
enum machine_mode vmode = TYPE_MODE (vec_type);
enum ix86_builtins fcode = fcode; /* Silence bogus warning. */
bool ok = TARGET_SSE2;
Also, I don't seem able to suppress this build failure with...
../gcc/configure --prefix=/Users/howarth/dist --enable-languages=c,c++
--enable-build-with-cxx --with-gmp=/sw --with-libiconv-prefix=/sw
--with-ppl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib
--x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
--enable-checking=release --disable-werror
Is that expected behavior in current gcc trunk?
