Bug ID: 104342
Summary: ICE with -gnata -fcallgraph-info=su
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: simon at pushface dot org
Target Milestone: ---

Requested source files
I originally found this error compiling for STM32F4, using both
ravenscar-sfp-stm32f4 and my cortex-gnat-rts equivalent. However, it
also shows up in a native compilation.
Neither option on its own caused a problem.
Compiling from the attached source with
gnatmake stm32-spi-dma.adb -c -u -f -gnata -fcallgraph-info=su
gives
gcc -c -gnata -fcallgraph-info=su stm32-spi-dma.adb
