This patch adds support for xstormy16's swap nibbles instruction (swpn).
For the test case:
short foo(short x) {
return (x&0xff00) | ((x<<4)&0xf0) | ((x>>4)&0x0f);
}
GCC with -O2 currently generates the nine instruction sequence:
foo: mov r7,r2
asr r2,#4
and r2,gcc-mirror#15
mov.w r6,#-256
and r6,r7
or r2,r6
shl r7,#4
and r7,#255
or r2,r7
ret
with this patch, we now generate:
foo: swpn r2
ret
To achieve this using combine's four instruction "combinations" requires
a little wizardry. Firstly, define_insn_and_split are introduced to
treat logical shifts followed by bitwise-AND as macro instructions that
are split after reload. This is sufficient to recognize a QImode
nibble swap, which can be implemented by swpn followed by either a
zero-extension or a sign-extension from QImode to HImode. Then finally,
in the correct context, a QImode swap-nibbles pattern can be combined to
preserve the high-byte of a HImode word, matching the xstormy16's swpn
semantics. The naming of the new code iterators is taken from i386.md.
2023-04-29 Roger Sayle <roger@nextmovesoftware.com>
gcc/ChangeLog
* config/stormy16/stormy16.md (any_lshift): New code iterator.
(any_or_plus): Likewise.
(any_rotate): Likewise.
(*<any_lshift>_and_internal): New define_insn_and_split to
recognize a logical shift followed by an AND, and split it
again after reload.
(*swpn): New define_insn matching xstormy16's swpn.
(*swpn_zext): New define_insn recognizing swpn followed by
zero_extendqihi2, i.e. with the high byte set to zero.
(*swpn_sext): Likewise, for swpn followed by cbw.
(*swpn_sext_2): Likewise, for an alternate RTL form.
(*swpn_zext_ior): A pre-reload splitter so that an swpn+zext+ior
sequence is split in the correct place to recognize the *swpn_zext
followed by any_or_plus (ior, xor or plus) instruction.
gcc/testsuite/ChangeLog
* gcc.target/xstormy16/swpn-1.c: New QImode test case.
* gcc.target/xstormy16/swpn-2.c: New zero_extend test case.
* gcc.target/xstormy16/swpn-3.c: New sign_extend test case.
* gcc.target/xstormy16/swpn-4.c: New HImode test case.

This patch contains some minor tweak to xstormy16's machine description
most significantly providing a pattern for HImode rotate left by a single
bit that requires only two instructions.
unsigned short foo(unsigned short x)
{
return (x << 1) | (x >> 15);
}
currently with -O2 generates:
foo: mov r7,r2
shr r7,gcc-mirror#15
shl r2,#1
or r2,r7
ret
with this patch, GCC now generates:
foo: shl r2,#1 | adc r2,#0
ret
Additionally neghi2 is converted to a define_insn (so that the RTL
optimizers see the negation semantics), and HImode rotations by
8-bits can now be recognized and implemented using swpb.

gcc/ChangeLog
* config/stormy16/stormy16.md (neghi2): Convert from a define_expand
to a define_insn.
(*rotatehi_1): New define_insn for efficient 2 insn sequence.
(*rotatehi_8, *rotaterthi_8): New define_insn to emit a swpb.
gcc/testsuite/ChangeLog
* gcc.target/xstormy16/neghi2.c: New test case.

This patch folds svindex with constant arguments into a vector series.
We implemented this in svindex_impl::fold using the function build_vec_series.
For example,
svuint64_t f1 ()
{
return svindex_u642 (10, 3);
}
compiled with -O2 -march=armv8.2-a+sve, is folded to {10, 13, 16, ...}
in the gimple pass lower.
This optimization benefits cases where svindex is used in combination with
other gimple-level optimizations.
For example,
svuint64_t f2 ()
{
return svmul_x (svptrue_b64 (), svindex_u64 (10, 3), 5);
}
has previously been compiled to
f2:
index z0.d, #10, #3
mul z0.d, z0.d, #5
ret
Now, it is compiled to
f2:
mov x0, 50
index z0.d, x0, #15
ret
We added test cases checking
- the application of the transform during gimple for constant arguments,
- the interaction with another gimple-level optimization.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
