Hi
I have noticed a potential problem with the use of the HAVE_xxx macros
defined in "insn-config.h" which is generated automatically from the
machine
description files by genconfig.
I have noticed than gcc/jump.c has code conditionally compiled dependent
on the definition of the HAVE_cc0 macro which is defined in insn-config.h
if the machine description supports CC0.
The problem is jump.c does not include insn-config.h either directly or
indirectly and thus will never see any definition of HAVE_cc0 that may
be in "insn-config.h"
The above example is almost definately not the only instanace where a
HAVE_xxx macro is tested, but insn-config.h has not been included.
Does anybody have any comments?
Graham

?!?
Line 60 in the current jump.c sources:
#include "insn-config.h"
