target/riscv/vector_helper.c: Remove the check for extra tail elements Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

target/riscv/vector_helper.c: skip set tail when vta is zero The function is a no-op if 'vta' is zero but we're still doing a lot of stuff in this function regardless. vext_set_elems_1s() will ignore every single time (since vta is zero) and we just wasted time. Skip it altogether in this case. Aside from the code simplification there's a noticeable emulation performance gain by doing it. For a regular C binary that does a vectors operation like this: ======= #define SZ 10000000 int main () { int *a = malloc (SZ * sizeof (int)); int *b = malloc (SZ * sizeof (int)); int *c = malloc (SZ * sizeof (int)); for (int i = 0; i < SZ; i++) c[i] = a[i] + b[i]; return c[SZ - 1]; } ======= Emulating it with qemu-riscv64 and RVV takes ~0.3 sec: $ time ~/work/qemu/build/qemu-riscv64 \ -cpu rv64,debug=false,vext_spec=v1.0,v=true,vlen=128 ./foo.out real 0m0.303s user 0m0.281s sys 0m0.023s With this skip we take ~0.275 sec: $ time ~/work/qemu/build/qemu-riscv64 \ -cpu rv64,debug=false,vext_spec=v1.0,v=true,vlen=128 ./foo.out real 0m0.274s user 0m0.252s sys 0m0.019s This performance gain adds up fast when executing heavy benchmarks like SPEC.

target/riscv/vector_helper.c: create vext_set_tail_elems_1s() Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added code to set the tail elements to 1 in the end of vext_ldst_stride(), vext_ldst_us(), vext_ldst_index() and vext_ldff(). Aside from a env->vl versus an evl value being used in the first loop, the code is being repeated 4 times. Create a helper to avoid code repetition in all those functions. Arguments that are used in the callers (nf, esz and max_elems) are passed as arguments. All other values are being derived inside the helper.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv/vector_helper.c: Remove the check for extra tail elements Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

target/riscv/vector_helper.c: Remove the check for extra tail elements Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

Aside from a env->vl versus an evl value being used in the first loop, the code is being repeated 4 times. Create a helper to avoid code repetition in all those functions.

target/riscv/vector_helper.c: Remove the check for extra tail elements Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

target/riscv/vector_helper.c: create vext_set_tail_elems_1s() Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added code to set the tail elements to 1 in the end of vext_ldst_stride(), vext_ldst_us(), vext_ldst_index() and vext_ldff(). Aside from a env->vl versus an evl value being used in the first loop, the code is being repeated 4 times. Create a helper to avoid code repetition in all those functions. Arguments that are used in the callers (nf, esz and max_elems) are passed as arguments. All other values are being derived inside the helper.

target/riscv/vector_helper.c: Remove the check for extra tail elements Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

target/riscv: rvv: Add tail agnostic for vv instructions According to v-spec, tail agnostic behavior can be either kept as undisturbed or set elements' bits to all 1s. To distinguish the difference of tail policies, QEMU should be able to simulate the tail agnostic behavior as "set tail elements' bits to all 1s". There are multiple possibility for agnostic elements according to v-spec. The main intent of this patch-set tries to add option that can distinguish between tail policies. Setting agnostic elements to all 1s allows QEMU to express this. This is the first commit regarding the optional tail agnostic behavior. Follow-up commits will add this optional behavior for all rvv instructions.

target/riscv: rvv: Add tail agnostic for vv instructions According to v-spec, tail agnostic behavior can be either kept as undisturbed or set elements' bits to all 1s. To distinguish the difference of tail policies, QEMU should be able to simulate the tail agnostic behavior as "set tail elements' bits to all 1s". There are multiple possibility for agnostic elements according to v-spec. The main intent of this patch-set tries to add option that can distinguish between tail policies. Setting agnostic elements to all 1s allows QEMU to express this. This is the first commit regarding the optional tail agnostic behavior. Follow-up commits will add this optional behavior for all rvv instructions.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged.

target/riscv: rvv: Add tail agnostic for vv instructions According to v-spec, tail agnostic behavior can be either kept as undisturbed or set elements' bits to all 1s. To distinguish the difference of tail policies, QEMU should be able to simulate the tail agnostic behavior as "set tail elements' bits to all 1s". There are multiple possibility for agnostic elements according to v-spec. The main intent of this patch-set tries to add option that can distinguish between tail policies. Setting agnostic elements to all 1s allows QEMU to express this. This is the first commit regarding the optional tail agnostic behavior. Follow-up commits will add this optional behavior for all rvv instructions.

According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv: Add tail agnostic for vv instructions According to v-spec, tail agnostic behavior can be either kept as undisturbed or set elements' bits to all 1s. To distinguish the difference of tail policies, QEMU should be able to simulate the tail agnostic behavior as "set tail elements' bits to all 1s". There are multiple possibility for agnostic elements according to v-spec. The main intent of this patch-set tries to add option that can distinguish between tail policies. Setting agnostic elements to all 1s allows QEMU to express this. This is the first commit regarding the optional tail agnostic behavior. Follow-up commits will add this optional behavior for all rvv instructions.

target/riscv: rvv: Add tail agnostic for vv instructions According to v-spec, tail agnostic behavior can be either kept as undisturbed or set elements' bits to all 1s. To distinguish the difference of tail policies, QEMU should be able to simulate the tail agnostic behavior as "set tail elements' bits to all 1s". There are multiple possibility for agnostic elements according to v-spec. The main intent of this patch-set tries to add option that can distinguish between tail policies. Setting agnostic elements to all 1s allows QEMU to express this. This is the first commit regarding the optional tail agnostic behavior. Follow-up commits will add this optional behavior for all rvv instructions.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.

target/riscv: rvv-1.0: add VMA and VTA Introduce vma and vta fields in vtype register. According to RVV 1.0 spec (section 3.3.3): When a set is marked agnostic, the corresponding set of destination elements in any vector or mask destination operand can either retain the value they previously held, or are overwritten with 1s. So, either vta/vma is set to undisturbed or agnostic, it's legal to retain the inactive masked-off elements and tail elements' original values unchanged. Therefore, besides declaring vta/vma fields in vtype register, also remove all the tail elements clean functions in this commit.
