Trying to call `patsopt_version` in the following simple program:
#include "share/atspre_define.hats"
#include "share/atspre_staload.hats"
implement main0 () = (
println!(patsopt_version());
exit_errmsg_void (0, "foo\n")
)
generates the compiler error:
/tmp/cc8XdQB8.o: In function `mainats_void_0':
patsver_dats.c:(.text+0x181): undefined reference to `atspre_patsopt_version
'
collect2: error: ld returned 1 exit status
and a couple warnings:
patsver_dats.c: In function ‘mainats_void_0’:
patsver_dats.c:343:1: warning: implicit declaration of function ‘
atspre_patsopt_version’ [-Wimplicit-function-declaration]
ATSINSmove(tmp2, atspre_patsopt_version()) ;
^
In file included from patsver_dats.c:15:0:
/home/spearman/ats/remote/ATS2-Postiats/ccomp/runtime/pats_ccomp_instrset.h:
270:35: warning: assignment makes pointer from integer without a cast [enabled
by default]
#define ATSINSmove(tmp, val) (tmp = val)
^
patsver_dats.c:343:1: note: in expansion of macro ‘ATSINSmove’
ATSINSmove(tmp2, atspre_patsopt_version()) ;
^
Commenting out the line to call `patsopt_version` compiles and runs
successfully emitting the exit message.
