[PATCH v4 0/1] RISC-V: Add support for 'XVentanaCondOps' reusing 'Zicond' support

[Tsukasa OI <research_trasio@irq.a4lg.com>]

PATCH v1:
<https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628786.html>
PATCH v2:
<https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628872.html>
PATCH v3:
<https://gcc.gnu.org/pipermail/gcc-patches/2023-September/629332.html>

Changes: v1 -> v2
*   Removed bogus opt2 pattern as pointed out in:
    <https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628867.html>
    note that this is not in the ChangeLog expecting the patch above
    applies first.

Changes: v2 -> v3
*   Instead of removing opt2 pattern, fix opt2 pattern:
    <https://gcc.gnu.org/pipermail/gcc-patches/2023-September/629137.html>

Changes: v3 -> v4
*   Leave only specific condition on {eq,ne}z_ventana code_attr.
    (eqz_ventana, nez_ventana): "maskcn" -> "n", "maskc" -> ""
    (*czero.<eqz>.<GPR><X>) "vt.<eqz_ventana>" -> "vt.maskc<eqz_ventana>"
    (*czero.<nez>.<GPR><X>) "vt.<nez_ventana>" -> "vt.maskc<nez_ventana>"
*   Testsuite:
    Reuse "zicond-*.c" (#include from "xventanacondops-*.c")
*   Minor Comment: ";; Zicond" -> ";; Zicond / XVentanaCondOps"
*   Rebase against commit e87212ead5e9 ("RISC-V: zicond: Fix opt2 pattern")

Wow, that was right.  It can be sometimes confusing but very useful
in this case.  Thanks for the info!


Sincerely,
