Subject: [PATCH 058/157] [Backport][SME] aarch64: Vector move fixes for
+nosimd
Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=721c0fb3aca31d3bf8ad6e929eab32e29a427e60
This patch fixes various issues around the handling of vectors
and (particularly) vector structures with +nosimd. Previously,
passing and returning structures would trigger an ICE, since:
* we didn't allow the structure modes to be stored in FPRs
* we didn't provide +nosimd move patterns
* splitting the moves into word-sized pieces (the default
strategy without move patterns) doesn't work because the
registers are doubleword sized.
The patch is a bit of a hodge-podge since a lot of the handling of
moves, register costs, and register legitimacy is so interconnected.
It didn't seem feasible to split things further.
Some notes:
* The patch recognises vector and tuple modes based on TARGET_FLOAT
rather than TARGET_SIMD, and instead adds TARGET_SIMD to places
that really do need the vector ISA. This is necessary for the
modes to be handled correctly in register arguments and returns.
* The 64-bit (DREG) STP peephole required TARGET_SIMD but the
LDP peephole didn't. I think the LDP one is right, since
DREG moves could involve GPRs as well as FPRs.
* The patch keeps the existing choices of instructions for
TARGET_SIMD, just in case they happen to be better than FMOV
on some uarches.
* Before the patch, +nosimd Q<->Q moves of 128-bit scalars went via
a GPR, thanks to a secondary reload pattern. This approach might
not be ideal, but there's no reason that 128-bit vectors should
behave differently from 128-bit scalars. The patch therefore
extends the current scalar approach to vectors.
* Multi-vector LD1 and ST1 require TARGET_SIMD, so the TARGET_FLOAT
structure moves need to use LDP/STP and LDR/STR combinations
instead. That's also what we do for big-endian even with
TARGET_SIMD, so most of the code was already there. The patterns
for structures of 64-bit vectors are identical, but the patterns
for structures of 128-bit vectors need to cope with the lack of
128-bit Q<->Q moves.
It isn't feasible to move multi-vector tuples via GPRs, so the
patch moves them via memory instead. This contaminates the port
with its first secondary memory reload.
