for ARM-Android
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: unassignedbugs at nondot.org
Reporter: samsonov at google.com
CC: eugeni.stepanov at gmail.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
I see the following error when compiling fresh compiler-rt test for
ARM-Android:
Sorry for not providing a short reproducer, but maybe someone would get insight
from the error message. Attaching preprocessed source and invocation command as
well.
