backends: allocate enough stace for null terminator
|
|
|
|
`gcc-15` added a new warning in https://gcc.gnu.org/PR115185:
|
|
|
|
i386_regs.c:88:11: error: initializer-string for array of 'char' is too long [-Werror=unterminated-string-initialization]
|
|
88 | "ax", "cx", "dx", "bx", "sp", "bp", "si", "di", "ip"
|
|
| ^~~~
|
|
|
|
`elfutils` does not need to store '\0'. We could either initialize the
|
|
arrays with individual bytes or allocate extra byte for null.
|
|
|
|
This change initializes the array bytewise.
|
|
|
|
* backends/i386_regs.c (i386_register_info): Initialize the
|
|
array bytewise to fix gcc-15 warning.
|
|
* backends/x86_64_regs.c (x86_64_register_info): Ditto.
