gas: Update fr_literal access in frag for GCC 10
When access fr_literal in
struct frag {
...
/* Data begins here. */
char fr_literal[1];
};
with
char *buf = fragp->fr_fix + fragp->fr_literal;
GCC 10 gave
gas/config/tc-csky.c: In function ‘md_convert_frag’:
gas/config/tc-csky.c:4507:9: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
4507 | buf[1] = BYTE_1 (CSKYV1_INST_SUBI | (7 << 4));
| ^
Change
char *buf = fragp->fr_fix + fragp->fr_literal;
to
char *buf = fragp->fr_fix + &fragp->fr_literal[0];
to silence GCC 10 warning.
* config/tc-csky.c (md_convert_frag): Replace fragp->fr_literal
with &fragp->fr_literal[0].
* config/tc-microblaze.c (md_apply_fix): Likewise.
* config/tc-sh.c (md_convert_frag): Likewise.
