Subject: [PATCH] gdb/arm: Add support for FPU registers in prologue unwinder
Date: Tue, 31 May 2022 15:33:36 +0200	[thread overview]
Message-ID: <20220531133336.GC13232@gnbcxd0114.gnb.st.com> (raw)

Hi,

The prologue unwinder had support for FPU registers, but only to
calculate the correct offset on the stack, the values were not saved.
