[lldb][AArch64/Linux] Show memory tagged memory regions This extends the "memory region" command to show tagged regions on AArch64 Linux when the MTE extension is enabled. (lldb) memory region the_page [0x0000fffff7ff8000-0x0000fffff7ff9000) rw- memory tagging: enabled This is done by adding an optional "flags" field to the qMemoryRegion packet. The only supported flag is "mt" but this can be extended. This "mt" flag is read from /proc/{pid}/smaps on Linux, other platforms will leave out the "flags" field. Where this "mt" flag is received "memory region" will show that it is enabled. If it is not or the target doesn't support memory tagging, the line is not shown. (since majority of the time tagging will not be enabled) Testing is added for the existing /proc/{pid}/maps parsing and the new smaps parsing. Minidump parsing has been updated where needed, though it only uses maps not smaps. Target specific tests can be run with QEMU and I have added MTE flags to the existing helper scripts.

[LLDB] Add QEMU testing environment setup guide for SVE testing This patch adds a HowTo document to lldb docs which gives instruction for setting up a virtual environment based on QEMU emulator for LLDB testing. Instruction in this document are tested on Arm and AArch64 targets but can easily be duplicated for other targets supported by QEMU. This helps test LLDB in absence for modern AArch64 features not released in publicly available hardware till date. Reviewed By: labath Differential Revision: https://reviews.llvm.org/D82064 | 5 年前 |
