Summary: arm: disassembly of pc-relative ldrd instructions not
fully annotated in Thumb
Product: binutils
Version: 2.22 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sources.redhat.com
ReportedBy: dave.mar...@linaro.org
The annotation of ldrd instructions in Thumb during
disassembly appears incomplete: the target label is not
annotated, whereas for ldr, or for ldr or ldrd in ARM, the
instruction is annotated with the target label in the
disassembly.
I believe the generated instruction encoding is right in the case
shown below, but it might be a good idea to double-check.
Cheers
