Before and after tree dumps for uninit-pred-8_a.c on ARM Cortex-M7
Hi Prathamesh,
gcc.dg/uninit-pred-8_a.c bogus warning (test for bogus messages, line 20)
started to fail for arm-none-eabi after your commit r241915 when targeting ARM
Cortex-M7. The test PASS for ARM Cortex-M4 (which share the same ISA with ARM
Cortex-M7).
I'm attaching the tree dump before (good) and after (bad) the commit. Please
let me know if you need anything else to analyse the issue.
Best regards,
Thomas
