Bug ID: 118564
Summary: DSP instruction support missing for ARM Cortex M4
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: anstein99 at googlemail dot com
Target Milestone: ---
ARM Cortex M4 does support DSP instructions. An example chip with a Cortex M4
and DSP instructions is STM32F411CEU6. The Cortex M4 DSP instructions are
listed at:
https://developer.arm.com/documentation/100166/0001/Programmers-Model/Instruction-set-summary/Table-of-processor-DSP-instructions
As of arm-none-eabi-gcc version 14.2.0 gcc does not support "+dsp" for
"-mcpu=cortex-m4" which it should as these instructions are available.
