Subject: [PATCH 0/1] RISC-V: Minor fix to the 'Ztso' extension support
Date: Wed, 21 Sep 2022 06:40:42 +0000	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

Hi all,

I think Shihua could have missed my review 2:
(see near the end of my e-mail starting with "Other than that,").

Currently, it sets EF_RISCV_TSO ELF flag when initial ISA string contains
the 'Ztso' extension.  However, GAS has a way to update the ISA string:
".option arch".

When the architecture is updated by ".option arch", EF_RISCV_RVC ELF flag
is set when the 'C' extension is detected.  Analogously, this patchset sets
the EF_RISCV_TSO when the 'Ztso' extension is detected.

With this patch, the 'Ztso' extension support will be complete.

  RISC-V: Set EF_RISCV_TSO also on .option arch
