Subject: [PATCH v2 0/5] linux-user/i386: Emulate orig_ax
Date: Thu, 12 Sep 2024 11:28:19 +0200	[thread overview]
Message-ID: <20240912093012.402366-1-iii@linux.ibm.com> (raw)

v1: https://lore.kernel.org/qemu-devel/20240802095942.34565-1-iii@linux.ibm.com/
v1 -> v2: Move orig_ax declaration higher, simplify gdb_write_reg()
          for TARGET_LONG_BITS == 32 (Richard).

Hi,

Currently gdbstub is barely usable with i386-linux-user: GDB cannot
even parse a shared library list, so no symbols are available. This
boils down to unavailability of info proc, which is gated behind
org.gnu.gdb.i386.linux. See amd64_linux_init_abi(); info proc is
enabled by amd64_linux_init_abi_common() -> linux_init_abi().

This series adds orig_ax support to the emulator and gdbstub, and
enables the existing test-proc-mappings.py on i386.

Best regards,
Ilya
