Even when this has been worked around by the binutils change, polyml
still fails to build.
echo "use \"/home/amodra/src/polyml/modules/IntInfAsInt/ROOT.sml\";" |
../../poly -q -error-exit
Segmentation fault
Some debugging shows this is due to a NULL function pointer, traceable
back to this relocation in polyexport.o
0134 1301 R_PARISC_DIR32 PolyProcessEnvGeneral + 0
That's also an ABI violation. Function pointers on hppa32 require
plabel relocations.
$ cat funcp.c
extern void foo(void);
void (*fp)(void) = foo;
