According to the syntax defined in C99, each struct/union field must have an
identifier. This patch adds names to the previously unnamed fields for C99
compatibility.
Here is a summary of the names (marked with a pair of *stars*) added.
struct trusty_mem:
union {
struct {
struct key_info key_info;
struct trusty_startup_param startup_param;
} *data*;
uint8_t page[CPU_PAGE_SIZE];
} first_page;
struct ptdev_remapping_info:
union {
struct ptdev_msi_info msi;
struct ptdev_intx_info intx;
} *ptdev_intr_info*;
union code_segment_descriptor:
uint64_t value;
struct {
union {
...
} low32;
union {
...
} high32;
} *fields*;
similar changes are made to the following structures.
* union data_segment_descriptor,
* union system_segment_descriptor,
* union tss_64_descriptor, and
* union idt_64_descriptor
struct trace_entry:
union {
struct {
uint32_t a, b, c, d;
} *fields_32*;
struct {
uint8_t a1, a2, a3, a4;
uint8_t b1, b2, b3, b4;
uint8_t c1, c2, c3, c4;
uint8_t d1, d2, d3, d4;
} *fields_8*;
struct {
uint64_t e;
uint64_t f;
} *fields_64*;
char str[16];
} *payload*;
