Hello,
I'm trying to use a crosscompilation version of egcs for powerpc.
This works fine, but it uses sjsl exceptions (which adds runtime
overhead).
Is there a way to use the powerpc as target without sjsl exceptions
(but still with exceptions) ?
It seems that the definition of INCOMING_RETURN_ADDR_RTX is missing.
(in gcc/defaults.h :
/* If we have a definition of INCOMING_RETURN_ADDR_RTX, assume that
the rest of the DWARF 2 frame unwind support is also provided. */
#if !defined (DWARF2_UNWIND_INFO) && defined (INCOMING_RETURN_ADDR_RTX)
#define DWARF2_UNWIND_INFO 1
#endif
)
DWARF2_UNWIND_INFO is not set anywhere in gcc/config/rs6000
as INCOMING_RETURN_ADDR_RTX.
This results in '__throw' and other stuff not being included in
libgcc.a
(oh yes, this is with egcs-980302)
Greetings,
