/* Declare the variable flag_half_pic as 'int' instead of 'extern

|
|
int', so that BSS variables are created (even though this is not
|
|
|
|
strict ANSI). This is because rtl.c now refers to the
|
|
|
|
CONSTANT_ADDRESS_P macro, which in turn refers to flag_half_pic,
|
|
|
|
and wants to call half_pic_address_p, whose address we also store
|
1999-08-26 09:30:50 +00:00
|
|
|
in a BSS variable. This way, the gen* programs won't get
|
1996-09-18 05:35:50 +00:00
|

unknown symbol errors when being linked (flag_half_pic will never

be true in the gen* programs). */
