Trying to compile today's parrot on:
SunOS xxx 5.8 Generic_117350-02 sun4u sparc SUNW,Ultra-5_10
with Sun's compiler:
cc: WorkShop Compilers 4.2 30 Oct 1996 C 4.2
it failed with the following errors:
src/pmc/float.c
"/home/doughera/src/parrot/parrot-cc/tools/build/../../lib/Parrot/Pmc2c/PCCMETHOD.pm",
line 465: warning: statement not reached
[ repeated 17 times ]
"./src/pmc/float.c", line 3340: non-constant initializer: op "U*"
"./src/pmc/float.c", line 3341: non-constant initializer: op "U*"
"./src/pmc/float.c", line 3342: non-constant initializer: op "U*"
[ 21 more similar errors ]
"./src/pmc/float.c", line 3454: cannot recover from previous errors
Looking at src/pmc/float.c, the first lines in question are:
const multi_func_list _temp_multi_func_list[] = {
{ CONST_STRING(interp, "is_equal"), /* line 3340 */
CONST_STRING(interp, "IJPP"), /* line 3341 */
CONST_STRING(interp, "Float,Float"), /* line 3342 */
(funcptr_t) Parrot_Float_multi_is_equal_Float },
which ultimately expand to:
const multi_func_list _temp_multi_func_list[] = {
{ ( interp ) -> const_cstring_table [ 515 ],
( interp ) -> const_cstring_table [ 84 ],
( interp ) -> const_cstring_table [ 639 ],
(funcptr_t) Parrot_Float_multi_is_equal_Float },
which indeed are non-constant initializers. GNU cc accepts this, as do
more modern compilers from Sun (such as version 5.9). I'm guessing it's
a C99 thing, but I don't actually know.
What to do about it? I suppose I could go in and rewrite those statements
(and similar ones that crop up in other PMCs) but I certainly won't
have any time to do that any time soon.
Should anyone care? It's certainly an old compiler, but it's the only
Sun compiler I have available on SPARC, and SPARC has often been a very
helpful platform for debugging alignment and endian issues in parrot.
