Subject: backends: allocate enough stace for null terminator
X-Git-Tag: elfutils-0.192~64
X-Git-Url: https://sourceware.org/git/?p=elfutils.git;a=commitdiff_plain;h=7508696d107ca01b65ce8273c881462a8658f90f
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.
