These could be inlined, though slightly harder.
C.f. target/arm/sve_helper.c, do_match2 (your n == 0).
Do you mean an inline like trans_vseteqz_v or just an inline
helper function?
I meant inline tcg code generation, instead of a call to a helper.
But even if we keep this in a helper, see do_match2 for avoiding
the loop over bytes.
Ok,
e.g
#define SETANYEQZ(NAME, MO) \
void HELPER(NAME)(CPULoongArchState *env, uint32_t cd, uint32_t vj) \
{ \
int i; \
bool ret = false; \
VReg *Vj = &(env->fpr[vj].vreg); \
\
ret = do_match2(0, (uint64_t)Vj->D(0), (uint64_t)Vj->D(1),
MO); \
env->cf[cd & 0x7] = ret; \
}
SETANYEQZ(vsetanyeqz_b, MO_8)
SETANYEQZ(vsetanyeqz_h, MO_16)
SETANYEQZ(vsetanyeqz_w, MO_32)
SETANYEQZ(vsetanyeqz_d, MO_64)
and
vsetanyeqz.b $fcc5 $vr11
v11 : {edc0004d576eef5b, ec03ec0fec03ea47}
------------------
do_match2
bits is 8
m1 is ec03ec0fec03ea47
m0 is edc0004d576eef5b
ones is 1010101
sings is 80808080
cmp1 is 0
cmp0 is edc0004d576eef5b
cmp1 is ec03ec0fec03ea47
cmp0 is 10000
cmp1 is 3000100
ret is 0
but, the results is not correct for vsetanyeqz.b. :-)
Well, 'ones' as printed above is only 4 bytes instead of 8, similarly
'sings'. That would certainly explain why it did not detect a zero
in byte 5 of 'm0'.
Some problem with your conversion of that function?
I copied do_match2 from arm. and my host is x86 machine.
...
uint64_t ones = dup_const(esz, 1); // esz = MO_8
uint64_t signs = ones << ( bits -1 ); // bits = 8
...
the dup_const() return 0x101010101010101.
but set the 'ones' is 0x1010101.
Oh, I didn't include the 'tcg/tcg.h' header file.
Thanks.
