--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
Smaller testcase:
typedef unsigned char cfg_u8;
typedef union {
struct {
cfg_u8 offset;
cfg_u8 value;
};
struct {
cfg_u8 command;
cfg_u8 param;
};
} cfg_reg;
#define FOO { 0x00, 0x00 },
#define FOO1 FOO FOO FOO FOO FOO FOO FOO FOO FOO
#define FOO2 FOO1 FOO1 FOO1 FOO1 FOO1 FOO1 FOO1 FOO1
cfg_reg tas5756m_init_hf3[] = { FOO2 };
now repeat more initializers (the original testcase has plenty).
I'd say the warning should be rate-limited somehow or simply only warn
once per array element type, not for reach element initialized. In this
case the warning is even questionable since the structs are anonymous?
