Hi!
We have in rs6000-protos.h
extern bool legitimate_indirect_address_p (rtx, int);
and in rs6000.c
inline bool
legitimate_indirect_address_p (rtx x, int strict) { ... }
and in predicates.md call this function. That works fine in C
(both -fgnu89-inline mode and C99), the function is inlined within rs6000.c
but an out of line copy is still emitted and predicates.md can thus
reference it. But in C++, if compiled with optimizations, without
-fkeep-inline-functions and the compiler inlines all calls to that function,
it doesn't have to emit anything. Thus, either we have the option to
move the definition of legitimate_indirect_address_p into a header (but
rs6000-protos.h doesn't look like a correct spot to define inline
functions), or we need to drop inline keyword and force that way
an out of line copy. Ok for trunk?
