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: <cover.1663742326.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <CAPpQWtBusmNDhezv2+4XjMGY_2B9Vuv7tNDqSJniKJOYaxi5gw@mail.gmail.com>
Hi all,
I think Shihua could have missed my review 2:
<https://sourceware.org/pipermail/binutils/2022-September/122916.html>
(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.
Thanks,
