Subject: [PATCH v2 00/21] Hexagon (target/hexagon) update
Date: Wed, 31 Mar 2021 22:53:12 -0500	[thread overview]
Message-ID: <1617249213-22667-1-git-send-email-tsimpson@quicinc.com> (raw)

This patch series is a significant update for the Hexagon target
    The first 10 patches address feedback from Richard Henderson
    <richard.henderson@linaro.org>
    The next 6 patches add the remaining instructions for the Hexagon
    scalar core

The patches are logically independent but are organized as a series to
avoid potential confilcts if they are merged out of order.

Note that the new test cases require an update toolchain/container.


*** Changes in v2 ***
Address feedback from Richard Henderson <richard.henderson@linaro.org>
    Break utility function (arch.c) changes into 2 separate patches
    Change bit-reverse addressing from TCG generation to helper
    Change loadalign[bh] to use shift+deposit
    Remove fGET_TCG_tmp
        Remove unneeded ireg and tmp variables
    Remove unused one variable from gen_log_predicated_reg_write
    Rename gen_exception to gen_exception_raw
    Remove unreachable tcg_gen_exit_tb
    Remove redundant PC assignment
    Remove TARGET_HEXAGON code from parts_silence_nan
    Change roundrom to uint8_t in arch_recip_lookup and arch_invsqrt_lookup
    Rewrite fGEN_TCG_addp_c/fGEN_TCG_subp_c using tcg_gen_add2_i64
    Remove gen_carry_from_add64()
    Break "instructions with multiple definitions" into multiple patches
    Fix fINSERT_RANGE macro

Expand macros inside GET_EA_pci, GET_EA_pcr
Change fGEN_TCG_PCR to fGEN_TCG_LOAD_pcr to be consistent with other macros
Cleanup load and unpack implementation
Cleanup load into shifted register implementation
Cleanup brev.c test case
Change sfinvsqrta/sfrecipa to use a single helper
Cleanup vacsh helpers
