Subject: [PATCH 0/4] linux-user/i386: Emulate orig_ax
Date: Fri, 2 Aug 2024 11:59:13 +0200 [thread overview]
Message-ID: <20240802095942.34565-1-iii@linux.ibm.com> (raw)
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
