Avoid using common symbols in v850 libgloss I've had this lying around for probably a year or two at this point. It just changes all the instance of "errno" from a common symbol to an extern. I can't offhand recall where the actual definition is, but it certainly exists in the generic code. 2022-03-20 08:01:33 +08:00			`extern int errno;`

Fix various v850 problems These fixes fall into a few different buckets. First c99 doesn't allow a parameter without a type. So in cases where the type had previously been an implicit int, make it an explicit int. Second, for return values, don't allow them to be implicit ints either, make them explicit. In a few cases change c89 function definitions to c99 function definitions. Lastly include <stdlib.h> in sbrk.c to get the prototype for abort () which we call when we detect a heap/stack collision. 2023-12-20 11:54:37 +08:00			`int`
