Subject: [PATCH 0/3] semihosting: Fix a few semihosting bugs
Date: Fri, 17 Oct 2025 17:35:26 -0400 [thread overview]
Message-ID: <20251017213529.998267-1-sean.anderson@linux.dev> (raw)
While discussing [1], it came to my attention that QEMU does not
properly truncate/error SYS_FLEN on 32-bit systems. Fix this, and some
other bugs with GDB File I/O that I found while working on this series.
That said, GDB File I/O has been substantially broken for two years now,
so it makes me wonder if anyone actually uses it! It would certainly
simplify the implementation if we didn't have to support it.
