So if I do:
> tar xvjf binutils-2.17.tar.bz2
> cd binutils-2.17
> CC=tcc ./configure --disable-nls --disable-shared --disable-multilib \
> --program-prefix=withtcc-
> make
So it dies with:
> tcc -c -DHAVE_CONFIG_H -g -I. -I.././libiberty/../include -Wc++-compat \
> .././libiberty/cp-demangle.c -o cp-demangle.o
> .././libiberty/cp-demangle.c:3825: constant expression expected
And the offending line is:
> cplus_demangle_init_info (mangled, options, len, &di);
>
> {
> #ifdef CP_DYNAMIC_ARRAYS
> __extension__ struct demangle_component comps[di.num_comps];
^^^ that one
> __extension__ struct demangle_component *subs[di.num_subs];
I.E. it's dying due to lack of "dynamic arrays".
We have alloca() now, so in the compiler can implement this as something
vaguely like:
struct demangle_component *__hidden_comps_ptr = \
alloca(sizeof(struct demangle_component)*di.num_comps);
#define comps (*__hidden_comps_ptr);
Except that sizeof(comps) will return sizeof(struct demangle_component *)
instead of the size passed to alloca().
Any opinions on how to tackle this one?
