[PATCH 0/2] RISC-V: Use only real extension names on testsuite

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

Hi,

Most of the RISC-V GAS testsuite uses real extension names but there are a
few counterexamples.  I will talk about following tests:

-   b-ext{,-64} for ("Zb*" except "Zbk*")
-   k-ext{,-64} for ("Zk*" and "Zbk*")

They:
-   provide unnecessary confusion (that major "B" and "K" extensions exist),
    for example shown in:
    <https://sourceware.org/bugzilla/show_bug.cgi?id=29341> and
-   do not test separate extension
    (they are multiple subextensions).

To avoid confusion and test individual extensions separately, this patchset
provides per-extension testcases and removes b-ext{,-64} and k-ext{,-64}.

There's another effect.  Splitting "B" testcases will clarify that "zext.h"
and "zext.w" (seemingly similar) instructions belong to different extension:

-   "zext.h" (RV32/64_Zbb)
-   "zext.w" (RV64_Zba)  <-- not Zbb!

[Changes]

-   Split b-ext and b-ext-64 to:
    -   zba{,-64}
    -   zbb{,-64}
    -   zbc
    -   zbs{,-64}
-   Reuse existing "zk*" and "zbk*" testcases because they are fine as is,
-   Add new testcases for separate extension:
    -   zkr (along with 'Zicsr', to test "seed" CSR accessibility)
    -   zkt (just to test extension support)
-   Remove:
    -   b-ext{,-64}
    -   k-ext{,-64}

For vector-insn*, I'll leave this for now but it might possible to split
(e.g. to three testcases for two instruction classes and INSN_V_EEW64).
Still, I think this is not as important as b-ext{,-64} and k-ext{,-64} and
I don't complain about using vector-insn* names themselves.

Thanks,
Tsukasa
