Subject: [PATCH v2 00/57] target/arm: First slice of MVE implementation
Date: Mon, 14 Jun 2021 16:09:10 +0100	[thread overview]
Message-ID: <20210614151007.4545-1-peter.maydell@linaro.org> (raw)

This patchseries provides an initial slice of the MVE
implementation. (MVE is "vector instructions for M-profile", also
known as Helium).

The series covers:
 * framework for MVE decode, including infrastructure for
   handling predication, PSR.ECI, etc
 * tail-predication forms of low-overhead-loop insns (LCTP, WLSTP, LETP)
 * basic (non-gather) loads and stores
 * pretty much all the integer 2-operand vector and scalar insns
 * most of the integer 1-operand insns
 * a handful of other insns
but is not (by a long way) complete MVE support, and this code
will remain 'dead' until the enable-MVE patch eventually lands.

Changes v1->v2:
 * Addressed code review comments
 * Where some style changes were suggested and made for patches at
   the beginning of the series I have retained the r-by tags for
   later patches which had minor changes to follow that style:
    - adding 'static const' for function pointer arrays
    - using mve_check_qreg_bank()
    - compressing the early-return-false and early-return-true
      checks in trans functions down to fewer lines
    - pass only ESIZE, not H, to macros in mve_helper.c
    - adjustments to handling of QC

Patches still in need of review are:
   04 "target/arm: Add handling for PSR.ECI/ICI"
   07 "target/arm: Implement MVE WLSTP insn"
   11 "target/arm: Implement MVE VLDR/VSTR (non-widening forms)"
   13 "target/arm: Move expand_pred_b() data to translate.c" (new patch)
   14 "target/arm: Implement MVE VCLZ"
   17 "target/arm: Implement MVE VREV16, VREV32, VREV64"
   19 "target/arm: Implement MVE VABS"
   21 "tcg: Make gen_dup_i32() public" (new patch)
   22 "target/arm: Implement MVE VDUP"
   34 "target/arm: Implement MVE VRMLALDAVH, VRMLSLDAVH"
   35 "target/arm: Implement MVE VADD (scalar)"
   45 "target/arm: Implement MVE VQSHL (vector)"
   53 "target/arm: Implement MVE VADC, VSBC"
   55 "target/arm: Implement MVE VHCADD"

Nobody seemed to object when I posted v1, so I propose to land
these via target-arm.next once they pass code review.

thanks
