Bug ID: 23725
Summary: Unable to record ARM Thumb2 PLI and PLD instuctions
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: record
Assignee: unassigned at sourceware dot org
Reporter: tpiepho at gmail dot com
Target Milestone: ---

Attempting to record a program built using the Linaro 2018.05 ARMv7 toolchain

Process record does not support instruction 0xf890f000 at address 0x76d95fc0.

This was caused by a PLD instruction used in the C library strlen() function.

=> 0x76d95fc0 <+0>: pld [r0]

GDB not recognize the PLD and PLI instructions in thumb2 encoding. It does
recognize them in ARM encoding, but this library is using thumb2.
